Horrified: World of Monsters

How do you play Horrified: World of Monsters?

Horrified: World of Monsters is a cooperative game. Your group wins only when every chosen monster is defeated. Each monster has its own challenge, and usually you cannot attempt the final Defeat action before completing that challenge. Between Hero turns, the Monsters attack, putting pressure on the team’s shared supply of time and Terror.

Every turn has two consecutive parts: the active player’s Hero Phase, then the Monster Phase. The Hero uses their printed allowance of actions to move, collect items, rescue Citizens, trade resources or advance challenges. At the end, reveal a Monster card to spawn more items, perform an Event and resolve attacks. The game proceeds clockwise to the next Hero.

You lose if the Terror marker reaches its maximum or if you must draw a Monster card and the deck is already empty. You do not lose merely because a single Hero is defeated: that Hero returns on their next turn at the Reviving Throne, but Terror still rises.

The recommended first-game combination is Yeti and Sphinx. Two monsters make a novice scenario; three monsters make the standard difficulty; any four create a challenging game. Even in a two-monster setup, no player wins individually or collects a separate competitive score.

Setup: four lairs, four monsters and five Hero options

Place the main gameboard and shuffle the four Lair tokens face down at the marked spaces: Door of the World, Garden of the Risen, Spindlewood Institute and Thornville Woods. A facedown lair has an unknown identity. Do not automatically reveal the Yeti’s Cave or the Moon Shrine just because a corresponding monster was chosen.

Put the Terror marker on zero for a normal multiplayer game. Shuffle the 30 Monster cards and place the 10 Citizen standees nearby with three attack dice. Select the monsters your group will face; arrange their Monster mats from lowest to highest Frenzy Order, place figures at the printed numbered starting locations, and carry out the special setup instructions on the mats.

Give each player a Hero tile, standee and reference card. There are five different Hero options in this box. Place each Hero on the starting location named on their own tile, then give each player one starting Perk card. The rest of the 20 Perk cards form a face-down deck.

Put the 60 item tokens in the bag, draw 12 and place them at the locations printed on those tokens. Keep the remaining tokens and monster-specific components in the box or supply until their instructions call for them. Cthulhu uses a separate second Monster mat and extra pieces only when the battle shifts to R’lyeh.

First-game setup: use Yeti and Sphinx. The Yeti needs three children tokens, while the Sphinx begins with a drawn item on its puzzle grid. You do not need the Jiangshi’s coin-sword pieces or Cthulhu’s runic puzzle in that introductory game.

Hero Phase: all available actions and what they cost

The active Hero may perform up to the number of actions printed on their tile. Choices can be repeated and used in any order, and the team can stop before spending its entire allowance. Each of the following normally costs one action unless a printed special ability says otherwise:

1. Move: move to an adjacent connected location, taking any number of Citizens at your location along with you.
2. Guide: move a Citizen from your location to a neighboring space or bring one from a neighboring space into yours.
3. Pick Up: collect any number of items from your current location with one action.
4. Share: permit Heroes at your location to exchange any number of items. You do not have to be personally involved in the exchange.
5. Advance: spend or use items under an individual monster’s task instructions.
6. Defeat: complete a monster’s final requirement after its earlier challenge has been cleared.
7. Special Action: use the ability printed on the Hero tile; check whether its text makes it action-free or limits frequency.
8. Reveal a Lair: at an unrevealed lair token, spend items of any color totaling at least three strength to uncover it.

Sharing is not an automatic free transfer whenever Heroes pass each other; it is a deliberate action unless a Perk or power overrides normal timing. Perk cards are action-free and any player may play them during another player’s Hero Phase. Discussing Perks before committing scarce actions can change a difficult turn.

Items: why shape, color, count and strength are different

World of Monsters uses three item types, indicated by the outline around each item’s strength value. A purple hexagon is a Weapon, a green circle is an Arcane item, and a blue square is a Mundane item. Each piece also has its own printed strength, name and board location.

When a task shows an item shape, its rules generally allow one item of that shape per action. When a task shows an item color and a numerical threshold, you may normally spend enough items of the named color to meet that combined strength. When the item requirement is shown in black, the task allows any item type as specified by its text.

This distinction is crucial. Defeating Jiangshi needs Weapon items totaling at least nine strength, whereas soothing the Yeti needs one of each of the three types. Having three high-strength Weapons does not satisfy the Yeti’s one-of-each requirement.

Illustrative payment: one Arcane item with strength 4 and one Arcane item with strength 2 together provide six strength for the Sphinx’s finishing condition. In contrast, a task instructing you to discard precisely one item allows only that single piece in that action, even if your hand contains more.

When items are spent or discarded, put them in the item discard area. If the bag must supply an item while empty, refill it from the item discard pile. This recycling rule does not apply to the 30-card Monster deck: the Monster deck is the game’s nonrenewable turn clock.

Reveal a Lair: the two monster lairs and two decoys

The four hidden lairs in World of Monsters are shuffled at Door of the World, Garden of the Risen, Spindlewood Institute and Thornville Woods. To uncover one, a Hero must be standing on its facedown token. They use one action and discard items totaling three or more strength in any colors.

The token then becomes face up and stays revealed for the rest of the game, whether or not its particular monster is being used. The four tokens consist of Moon Shrine (for Jiangshi), Yeti’s Cave (for Yeti), and two blank decoy lairs. The decoys are part of the base game and can cost the team a reveal action without providing a monster objective. Greek Monsters’ Statue Garden and Labyrinth are not included as native World of Monsters lairs; importing them requires the separate official combining rules.

Do not confuse the lair icon with the printed location’s name. A Hero arriving at Spindlewood Institute knows there is a token there, but does not know which lair it is until paying the reveal cost. Finding the wrong lair still exposes information and narrows the other possibilities, but costs resources that might be needed for a monster’s task or self-defense.

Some monsters—Sphinx and Cthulhu—do not need you to uncover a lair to start their objectives. Cthulhu uses the Void, a named board location, followed by a separate R’lyeh mat. That is different from a facedown Lair token.

The Monster Phase: draw, Event, strikes and Frenzy

At the end of a normal Hero turn, draw one Monster card and resolve its three sections in order. First, draw item tokens from the bag and place them at their printed locations. Second, resolve the Event. An Event naming an inactive or already defeated monster is ignored where the instruction specifies. Third, resolve the Monster Attack strip from left to right.

Each colored symbol activates the matching monster or monsters. A Frenzy symbol activates the monster holding the Frenzy marker; it can act even if it was activated by its own color elsewhere on the same card. Resolve each activation individually, including movement, attack dice and powers.

Normally a monster moves on the shortest paths toward the nearest Hero or Citizen and stops upon reaching someone. When distances tie, Heroes are preferred. If multiple Heroes are tied, the active player chooses the target. If there are no characters in the monster’s location after movement, it generally does not attack.

If an attack is made, roll the number of dice printed on the card. Resolve Power results before Hits, as the Power might move a figure or produce damage of its own. Then an ordinary Hero can block one Hit by discarding one item of any kind, unless the current monster power imposes a stricter defense. If an unblocked Hit defeats the Hero, advance Terror one space and remove that Hero temporarily. On their next turn the Hero returns to the Reviving Throne, keeping items and Perks.

A Citizen defeated by a hit is removed permanently and also increases Terror. You cannot normally discard a Hero’s items to defend a Citizen who is attacked. This makes rescue actions worthwhile when the board is crowded with monsters.

All four World of Monsters challenges at a glance

Unlike previous Horrified boxes with six or seven monsters, this standalone game includes four figures and five Monster mats. Cthulhu has two mats because its challenge changes setting partway through.

Choosing only two of these four still produces a full game. Yeti and Sphinx are the publisher’s recommended first pairing because their tasks teach item categories, routes and puzzles without the more elaborate coin-sword and multi-stage Cthulhu encounter.

Yeti: find its Cave and reunite the children

The Yeti has Frenzy Order 1 and is listed as a low-complexity monster. Its setup places three Yeti children at marked starting locations. These tokens are not ordinary Citizens: monster attacks and Perk cards do not treat them as Citizens, and they are not removed as ordinary rescue rewards.

First, the team needs to reveal Yeti’s Cave using the standard lair-discovery action. Then use Guide and allowed movement to escort all three children to that revealed Cave. Each arriving child is moved from the board onto the Yeti mat, recording the rescue. A child reaching the Cave is an Advance milestone, not an immediate monster defeat.

After all three have returned, a Hero at the Yeti’s current location can finish the challenge by spending one item of each type: Weapon, Arcane and Mundane. The three items do not need a particular combined strength. The presence of one of each shape is what matters.

The Yeti’s Power, Snow Blast, inflicts a Hit on the closest Hero or Citizen outside its own current location. It can therefore harm a supposedly safe distant character. A Hero in that target position may need to discard an item to absorb the Hit even when another Hero is standing with the Yeti.

Beginner planning: assign the Cave search and children rescue early while other players collect a complete finishing trio. Use nearby items to protect against Snow Blast without sacrificing the only example of a needed item type.

Sphinx: solve the item-strength grid

The Sphinx has Frenzy Order 2, low complexity and no lair. In setup, draw one item from the bag and put it on the specified starting square of its grid. That first item is fixed: it cannot be moved or removed, even when you revise later choices.

The task is to complete a number-sum puzzle. Each row and column of the mat has a printed target total. In the Sphinx’s location, a Hero spends an Advance action to put an item onto the grid, or uses an item for the allowed move-or-remove adjustment of an item already placed. Read the item-value numbers rather than trying to make matching colors.

When every row and column contains item strength totaling exactly its target, the riddle is solved. A Hero sharing the Sphinx’s location may then perform the Defeat action by spending Arcane items totaling six or more strength. Items committed to the puzzle are not necessarily the same items the group has available for this final payment.

The Sphinx’s Power, Lethal Conundrum, gives the group a choice: discard two items of equal strength or advance Terror one step. It does not require two identical item names or colors. If two Heroes between them hold one item each of strength 3 and can legally discard them for the effect, they satisfy the numerical condition.

Because the initial grid item is immovable, plan the remaining rows and columns around it before filling the board with random numbers. A useful move often depends on which strengths are currently in the item bag and which have already been collected by the group.

Jiangshi: the Moon Shrine and Coin Sword puzzle

Jiangshi has Frenzy Order 3 and medium complexity. Its task uses a special Coin Sword arrangement made from 11 pieces. First, discover the Moon Shrine beneath one of the four facedown lairs. Then a Hero standing at that Shrine can perform an Advance action by discarding an item to place a Coin Sword token matching the discarded item’s strength number.

The rules allow an Advance action to move or remove a Coin Sword piece already arranged, helping repair a flawed layout. The goal is to complete the prescribed sword pattern, not merely collect an arbitrary quantity of pieces. If you do not have items with helpful printed values, another member of the team may be better suited to supply them through Share.

After constructing the sword, a Hero sharing Jiangshi’s location completes its Defeat action with Weapon items totaling nine or more strength. A stack of Arcane or Mundane items with higher strength does not substitute for the Weapon-type requirement.

Jiangshi’s Power, Drain Vital Energy, makes it teleport to the location of the player whose turn is next, after damage from the current attack has been resolved. This changes the monster’s position before the next Hero acts, creating a threat but also potentially bringing the monster closer to someone already carrying its finishing Weapons.

Practical advice: organize the Coin Sword construction before spending the team’s most useful Weapon pieces on routine defense. Use inexpensive items when their strength matches a necessary coin token, and reserve enough Weapons for the final confrontation.

Cthulhu, phase one: align runes and open the Void

Cthulhu has Frenzy Order 4 and high complexity. It is the special multi-phase challenge that distinguishes World of Monsters from earlier entries in the line. Start by shuffling seven Runic tokens and revealing three onto Cthulhu’s first Monster mat, one beneath each numbered dial.

At the Void location, perform Advance actions to turn each dial until its displayed symbol matches the corresponding Rune. An item is discarded to rotate the matching-color dial a number of spaces equal to the item’s strength. The resulting dial position matters, so calculate how the rotation will land rather than assuming a high-value item is always better.

When all three dials match their runes, the portal is open. The next objective is to make Cthulhu enter the Void. It might reach that location by its normal movement, or a Hero standing with Cthulhu can spend an Arcane item to move the monster up to that item’s strength along the available paths.

Once Cthulhu is brought to the Void with the portal open, remove its figure from the ordinary map and set up the Corpse-City R’lyeh second-stage mat. Crucially, Cthulhu has not yet been defeated in the full version of the game.

Optional shorter scenario: the official rulebook permits treating Cthulhu as defeated after the successful portal step. That is an explicitly optional reduction in complexity and game length, not the standard complete multi-phase victory requirement.

Cthulhu, phase two: manacle the tentacles in R’lyeh

The second phase moves play into the Corpse-City R’lyeh. Assemble the special Cthulhu model on its second Monster mat and set aside four Manacle tokens. Draw one item from the bag and place it in front of the Cthulhu model as the item currently controlling its power.

The challenge is to bind all four tentacles. The mat gives spaces and item requirements for making progress. Heroes use Advance actions, paying eligible items as instructed, and can place a Manacle after meeting the printed condition. The rule distinguishes the color of the item from its type. Follow the mat’s exact item count and action timing: it restricts the number of items discarded per action and can change a Hero’s position based on item type.

Cthulhu’s R’lyeh Power, Tentacles of Insanity, can deal a special Hit to every Hero in the area matching the color of Cthulhu’s controlling item. These Hits can only be blocked by discarding an item of that same color. Each Power result changes the item controlling the attack, potentially changing which area is dangerous next.

With all four Manacles placed, every Hero must be present in R’lyeh for the final Defeat action. Use Share to assemble the required item contributions from the other Heroes, then discard the assembled items according to the second mat to imprison Cthulhu.

Unlike the Sphinx’s quick ending, this final confrontation benefits from planning the whole group’s position. Completing the last Manacle when teammates are stranded elsewhere may prolong the game enough for the Terror or Monster deck clock to end it first.

Since the complete R’lyeh procedure has detailed icon-specific positioning on its board, use the official rulebook text and Monster mat at the table rather than treating this prose guide as a replacement for the component diagrams.

The Monster deck clock: Terror, Power and losing conditions

Your two main ways to lose are maximum Terror and running out of Monster cards at a required draw. Terror rises when a Hero or Citizen is defeated, and certain Monster powers can increase it without a conventional attack. Cthulhu’s first-phase Touch of Madness can make the team choose between one extra Terror and discarding the top Monster card; both choices have costs.

The rule on an empty deck is precise. If the group draws and resolves the last Monster card, it still gets another Hero Phase. The loss occurs when a new Monster Phase actually calls for a card and none is left. This may grant exactly the final action window needed for the last Defeat action.

During Monster strikes, calculate targets and movement one monster activation at a time. A monster can be Frenzied and also activated by its own matching icon, causing two actions from a single card. The Frenzy marker progresses through the surviving monsters by Frenzy number as Events direct.

After a monster is defeated, remove it from the board and ignore later Events and attacks that name it. If that monster held Frenzy, transfer the marker to the next appropriate remaining monster. Successfully removing a monster therefore reduces future risk even before the team finishes the final challenge.

Solo rules: what changes for one Hero?

Horrified: World of Monsters supports one to five players. The published solo change is that the Terror marker starts at level three rather than level zero. This reflects how much harder it is for one investigator to protect the town and its Citizens.

Use the normal game structure with one Hero, the same chosen monster mat instructions, the regular item bag and a single Monster card after each Hero Phase. The box does not require a separate automated second Hero or a competitive opponent, and its solo rules do not introduce a distinct score to beat.

As with multiplayer play, the recommended beginner monsters are Yeti and Sphinx. In solo, consider the cost of backtracking for lairs and item exchanges: you cannot depend on another player’s turn to recover a helpful item from across town.

Do not copy solo restrictions from other Horrified editions without checking this rulebook. The original Universal Monsters and American Monsters boxes have edition-specific Hero/Perk restrictions, whereas this edition’s printed solo rule centers on the higher initial Terror.

Combining Horrified games: updated Ravensburger compatibility

The first World of Monsters instructions explicitly describe combining this game with Horrified: Greek Monsters. Ravensburger’s newer official combination guide expands this to include Horrified: Dungeons & Dragons. The three lines’ monsters and heroes can be used together, but you must follow the publisher’s mixing document rather than assume any component combination works automatically.

Choose the gameboard first. That game’s board determines the Monster deck, Perk deck, Lair tokens, item bag and the Citizens or Legends used for the session. Then choose visiting Heroes and Monsters from the supported boxes. Their starting locations need translating to unused Hero spaces or Frenzy-numbered monster starts on the chosen board.

Items also need translating when an imported monster expects a different type from another edition. The official guide shows examples using corresponding items across all three boxes. Under the revised guide, colored monster-attack icons take priority over shapes when determining which monsters a card activates.

If a visiting monster needs a lair, use the mixing guide’s blank Lair tokens and replacement rules, rather than simply declaring its lair is already found. Some monsters have unique destination adjustments: the guide supplies rules for Greek Basilisk and Medusa in World of Monsters and for Cthulhu or Yeti visiting Greek Monsters.

For exact exceptions, consult Ravensburger’s official combining Horrified games PDF. The older Universal Monsters and American Monsters editions are not part of this particular published cross-compatibility procedure.

World of Monsters versus the other Horrified editions

Universal Monsters (2019) is built around classic film monsters and their unique objectives. American Monsters (2021) substitutes cryptids with new color sets and puzzles. Greek Monsters (2023) introduced hidden lairs for Greek legends. World of Monsters (2024) has just four monster figures but broadens the supernatural theme and gives Cthulhu an unusual extended finale.

These are standalone boxes rather than four expansions for one original game. You can play World of Monsters independently without purchasing any earlier release. The officially documented mixing options with Greek Monsters and D&D are optional rather than required for normal play.

For the 2023 lair mechanic, see our Greek Monsters guide. If you want Dracula, the Wolf Man or the Creature, read Universal Monsters. For Bigfoot, Mothman and Chupacabra, explore American Monsters. The D&D adaptation has its own Ravenloft guide.

Keeping these pages edition-specific reduces confusion about Item colors, Hero starting locations, cards and monster challenges. A player arriving from a search for ‘Cthulhu R’lyeh Horrified rules’ should not be given Dracula coffin rules as though they were interchangeable.

Beginner strategy: choose routes, protect items and manage time

1. Start with Yeti and Sphinx. The publisher recommends these challenges for the first game. They teach hidden lairs and item puzzles before you handle Jiangshi or Cthulhu.
2. Search lairs with a budget. Revealing one needs three total strength. Pick a Hero who can visit multiple token sites efficiently rather than forcing an unnecessary long trip.
3. Use the correct item requirement. Jiangshi needs Weapon strength, Sphinx needs Arcane strength, and Yeti needs one of each type. Strength alone is not sufficient for every task.
4. Plan the grid before playing items. The Sphinx’s first item cannot move, so the remaining placements should fit its fixed row-and-column totals.
5. Rescue Citizens when routes overlap. A saved Citizen provides a free Perk and removes a target who otherwise might increase Terror.
6. Watch Cthulhu’s dual clock pressure. Its Power can burn Monster cards as well as Terror. An extended R’lyeh fight is only viable if the group has preserved enough turns.
7. Keep defensive items in reserve. A discarded item can prevent an ordinary Hit, but Cthulhu’s second phase demands matching colors for some special attacks.
8. Do not delay a ready defeat. Removing a monster usually also removes future Events and strikes targeting it, improving the group’s situation for the remaining tasks.

These are independent tactical suggestions based on the documented rules, not official rankings of monsters or claims of personal playtesting.

Horrified: World of Monsters FAQ

How many players can play World of Monsters?

One to five players. All players cooperate; the solo game begins with Terror at level three.

What are the four monsters?

Yeti, Sphinx, Jiangshi and Cthulhu. Cthulhu’s extra Monster mat accounts for the box having five mats but four monster figures.

Which monsters should beginners use?

The official first-game suggestion is Yeti and Sphinx. Three monsters are standard difficulty and four are challenging.

Is Cthulhu defeated after entering the Void?

Not in the full game. Moving Cthulhu through the opened Void begins the second R’lyeh phase. The rulebook offers treating it as defeated there as a shorter optional variant.

How does the Yeti task work?

Reveal Yeti’s Cave, escort all three children there, then meet Yeti and spend one each of Weapon, Arcane and Mundane items.

How do you solve Sphinx?

Fill its number grid so row and column strengths match printed targets. The starting item cannot be moved. Finish with Arcane items worth at least six strength.

What is the Coin Sword used for?

At the Moon Shrine, use item strengths to construct Jiangshi’s required Coin Sword pattern. Afterward defeat it with Weapon items totaling at least nine strength.

How do you reveal a lair?

Spend items of any color totaling three or more strength while standing on a facedown Lair token, using one action.

Do you reroll or recycle the Monster deck?

No. The finite Monster deck is the clock. The item bag recycles discarded items when empty, but Monster cards do not.

Where do defeated Heroes return?

At the Reviving Throne at the start of their next turn, keeping their items and Perks.

Can World of Monsters be played with Greek Monsters?

Yes. The included rules support mixing those two boxes; Ravensburger’s updated PDF also includes the D&D Horrified box using defined conversion rules.

Can I mix it with Universal Monsters or American Monsters?

Those editions are not included in Ravensburger’s specific published compatibility guide for Greek, World and D&D, so do not treat their cards, lairs or item types as automatically compatible.

Is the game suitable for solo play?

Yes. The published solo rule starts Terror at three, with the usual one-Hero turn procedure.

How long does a game take?

Ravensburger gives 45–60 minutes. The full Cthulhu challenge can be more involved, especially for an unfamiliar group.
