Eternal Decks
Keep a shared cycle alive while each stage changes the puzzle.
Eternal Decks is a cooperative card puzzle in which every player must keep their own deck alive. You place numbered cards into constrained Field rows, revive Eternals to refill a deck, and deal with the curses those revivals create. Each stage asks the group to reach a different goal before someone can no longer take a legal turn.
This guide starts with Stage A, then explains why the later stages and official solo rules matter when choosing a copy. Its tactical suggestions come from the designer’s published rules and are editorial inferences, not a report of personal play.
Why It Stands Out
Reviving an Eternal gives one player an eight-card deck and creates a curse for everyone. The group has to decide who needs the refill most, whether it can survive the new restriction, and how to communicate an intended play with limited clues.
About Eternal Decks
Hiroken designed Eternal Decks for Tricktakers Games, with artwork by MUJUNSHA. The 2025 game is listed for 1–4 players, age 10 and up, and roughly 30–40 minutes per stage. The six main stages A–F introduce different targets and constraints. The designer has posted updated English fourth-edition rulebooks, so check the booklet and file version when a detail differs.
Game at a Glance
1–4 players
Cooperate around the board, or use the included solo framework.
Three Field rows
Adjacent cards cannot share a number or color; each row adds rules.
Revive and curse
New cards extend a deck, but an Eternal changes the puzzle.
Six stages
Stage A seeks stars; later stages use their own key objectives.
How to Play Eternal Decks
Use Hiroken’s updated English rulebooks for setup diagrams, icons, stage sheets and exact exceptions. Stage A’s beginner mode is the best place to learn the shared system.
Set up Stage A
Arrange the Eternal decks, Field cards, stars, jewels and other stage components as shown in the rulebook. Each player begins with a five-card starting deck and two Communication Discs, then draws a starting hand. The Field has three rows; the River and other board spaces handle jewels, discards and stage progress.
Take one of three actions
On your turn, play a card, generate a Jewel, or give a card to a teammate, following the precise restrictions for that action. You must use at least one card on a turn; if you cannot, the whole group loses. Refill your hand and check end conditions as the rulebook directs.
Place cards legally
When placing a number card in a Field row, it cannot share a color or number with an adjacent card. The Stage A Mountain row also rises in number, Cave falls, and Camp uses the common adjacency restriction. Later Field cards replace those extra row rules. Rare and two-color cards have special handling; read the rulebook before treating one as a universal escape.
Revive an Eternal and handle its curse
Fill a row to its Eternal to revive one from that row. The player who completes it places that Eternal’s eight-card deck beneath their own deck. Clear the row as directed, then apply the revealed curse, which can block certain numbers or colors. Generate Jewels through the River to break curses. This means a refill can create the next team-wide problem.
Complete the stage
Stage A requires four stars. Stages B–F use four keys, with distinct ways to earn them. They are separate scenarios rather than six rounds of one game. If a player cannot use a card on a required turn, everyone loses before the objective is complete.
Eternal Decks Strategy & Practical Tips
The following principles are derived from the published placement and refill rules. Stage cards, curses, modes and player count change the best move.
- Count each player’s remaining turns. The player closest to an empty deck may need to complete a Field row and receive the Eternal’s eight cards. Do not automatically give the refill to the player who happens to have the easiest last card.
- Plan a row’s future numbers. Mountain’s ascending and Cave’s descending order can strand a row if an extreme number arrives too early. Check the next player’s likely legal range before placing.
- Use Camp as breathing room. Its lack of an extra ordering rule can absorb hands that are awkward for Mountain and Cave. It still follows the common color and number adjacency rule.
- Price in the curse. Before reviving, ask whether the group can keep playing under that Eternal’s restriction and whether a Jewel route is open to remove it. Eight new cards for one person may cost the table several good Field placements.
- Spend communication deliberately. The discs let you signal intended card locations without revealing every hand detail. State the group’s next objective in legal terms, then use the discs to coordinate the near-term sequence.
- Protect flexible cards. Rare or two-color cards can repair a narrow placement window, but their exceptions are specific. Saving one for a later bottleneck can be worth more than an easy early row advance.
- Change priorities with the stage. A star route in A is not the key route in B–F. Read the stage target first and decide which row completions, Jewels and abilities move it forward.
When should you try a harder mode?
Use Practice or Stage A beginner setup to learn turn structure and curses. Once the group can predict how a revival affects the next few turns, choose another stage or difficulty setup from the rulebook. A harder setup changes the resource puzzle; it is not just a score target.
Solo, Stages & Edition Notes
Is solo official?
Yes. The rulebook includes Solo Play — 3 Golems, with Basic rules and a Story Mode called “The Alchemist and the Cat.” Use those setup and communication-icon changes rather than simply playing one normal player seat. The exact solo objectives follow the selected stage.
Are the later stages expansions?
No. Stages A–F are part of the game’s scenario system. Stage A teaches stars; B–F ask for keys through different challenges. Practice, difficulty settings and several advanced stage variants also appear in the rulebooks. Pick a stage for one session rather than assuming a campaign is required.
Which rulebook version applies?
Hiroken’s English rulebook upload was updated in June 2026 with fourth-edition files. Printed copies and localized versions can differ. Match your edition’s components and stage sheets to the correct file, and use the designer’s update for clarified rules.
Do I need another game to play?
No. Eternal Decks is a standalone cooperative game. Other titles with “Eternal” in their names are separate products. Verify a listing’s language and rulebook edition before purchasing a copy.
Eternal Decks FAQ
Can one person play?
Yes. Follow the official three-Golem solo rules and their Basic or Story Mode setup.
Is it a conventional deck builder?
New eight-card Eternal decks enter a player’s deck when revived, but this is a cooperative placement and survival puzzle rather than a market-driven race for victory points.
How do you lose?
If a player cannot use at least one card on a required turn, the group loses. Stage-specific losses may also apply; read the chosen stage sheet.
What is the first stage’s goal?
Earn four stars in Stage A. The other main stages use four keys with distinct conditions.
How long is a session?
Listings estimate roughly 30–40 minutes per stage. A first read through the rulebooks and setup will add time.
