In The White Castle: Duel, you take 12 turns across an outgoing and a return round. Your turn uses a lantern token to pick a castle location, gives you a color-based lantern reward, then offers the two actions next to that location. The same physical location can change in value as activation tiles are swapped, cards are bought and tokens are stacked. This explanation follows Devir’s English rulebook and covers the base game for two players.
Set up the castle
Put the main board between the players. Shuffle the 36 influence cards together, split them randomly into three face-down decks of 12 with their cost sides up, and place them in the castle. Select and place the basic and elite training-yard tiles; reveal three lantern cards. Randomize six activation tiles and six location tiles into their assigned spaces. Set up the social-climbing paths, three stone and three plant garden tiles, and the common and luxury merchandise stacks as the rulebook specifies. For a first game, its illustrated fixed setup can replace the marked random setup steps.
Each player takes a domain board, three resource markers at zero, eight clan seals, a courtier at the castle gate, and six lantern tokens—two of each color. Give the starting marker to one player. The player who goes second chooses from the starting resource cards before the first player, as shown in the rulebook; both take their starting resources and lantern card. Coins and Daimyo seals share a storage limit of ten; food, iron and mother-of-pearl each have a track from zero to seven.
Four steps on every turn
- Optional swap: discard one Change Activation tile to exchange the positions of two activation tiles. This can be done once, at this point, before choosing the location.
- Place or retrieve one lantern token: the outgoing round places a token from your domain onto a location; the return round takes the top token from a stack and puts it in the matching color area of your domain.
- Take the lantern reward: activate the color you have just covered. Collect the printed reward and all visible rewards on lantern cards in that color’s area.
- Resolve the two neighboring actions: perform the two actions beside that location in either order, fully finishing one before the other. A neighbor may be an activation tile or an influence card you may purchase. For each action you cannot or choose not to take, choose one Well benefit instead.
Outgoing round: placement restrictions
On each of your six turns in round one, move one of your remaining lantern tokens onto a location. An empty location rejects a token whose color matches its printed lantern. An occupied location rejects any color already present in its stack. Thus, a stack can hold at most three tokens, one of each color. The new token covers the printed color if it is the first placed there, or the previous top token if it goes on a stack. The color covered, rather than the color you just played, grants the lantern reward. The location itself determines the two actions.
Example: suppose the printed lantern on a location is black. You place a white token there, so you trigger your black lantern area and may then resolve both adjacent actions. If a coral token is later stacked on that white token, its owner triggers their white lantern area. A black token could then go on top if the other color conditions permit; another white token could not.
Return round: the token can be your opponent’s
After both players have placed all six tokens, pass the starting player marker to the other player. That player acts first in the return round, so they take two consecutive turns around the round boundary. On each return turn, take the top token from any stack, even if your opponent originally placed it. Put it in the corresponding color area of your own domain. This time the color of the removed token is the color you cover and activate. You still gain the two actions next to the location from which it came. There is no stacking limit on your personal domain, so the distribution of colors you finish with may differ from the six you began with.
What do the six activation tiles do?
| Action | Core choice |
|---|---|
| Garden | Pay 2 or 5 food to place a clan seal in an empty garden space. Gain that column’s immediate reward; its icon also counts at the end. |
| Training | Pay 2 or 5 iron to place a seal in an empty training-yard space. Choose one displayed immediate reward; basic and elite placements are different end-game multipliers. |
| Courtier | Pay 2 or 5 mother-of-pearl to climb one or two spaces. Claim only the reward where you land. The first player to start climbing chooses a path; the other takes the other path. |
| Trade | Pay any one resource to buy a top influence card at its normal additional cost and perform its scroll, or pay any two resources for common merchandise, or any five for luxury merchandise. |
| Lantern | Activate any one of your three lantern colors, taking all its visible rewards. |
| Improve | Flip up to two influence cards you own so their printed reverse-side icons can count in final scoring. |
To buy a neighboring influence card, pay its displayed coins, Daimyo seals or mix of both, add it to your domain and resolve its scroll action if you wish. Its icons do not count at final scoring until you improve it. Declining a scroll action does not itself earn a Well benefit. If you skip an adjacent castle action or card purchase, the Well offers one resource, one Daimyo seal, one coin, one Change Activation tile or one clan point per skipped action. You may have at most two Change Activation tiles.
End the game and avoid common mistakes
After the twelfth turn for each player, the board’s last lantern has been retrieved. Add the icon multipliers and leftover resource points to the red fan points already recorded. See the complete scoring reference. The higher total wins; ties go to more clan seals placed, then to the higher courtier, then a shared victory.
- Covered color: in the outgoing round it may be the location tile or a prior token, while in the return round it is the token you picked up.
- Card timing: purchase grants the scroll effect now; improve grants end-game icons later. A purchased but unimproved card’s icons do not score.
- Two actions: you may do them in either order, but do not interleave one action with the other.
- Resource exchange: at any time you can discard two Daimyo seals for a resource of your choice, subject to its track limit.
