Core Loop

Hanamikoji is a two-player card game about courting seven geisha. The deck contains 21 cards (3 cards each for the two 2-point geisha, 4 cards for the two 3-point geisha, and proportional counts for the 4- and 5-point geisha). Each round both players draw one card secretly, then on their turn draw one card and perform one action from four available — each action may only be used once per round (tracked by markers).

The four actions are: Secret (discard 2 cards face down, scoring nothing), Tradeoff (place 2 cards face up; opponent chooses one set to keep, you take the other), Gift (play 3 cards face up; opponent picks 1 to keep, you keep the remaining 2), and Competition (lay out two pairs of cards; opponent picks which pair they want, you keep the other). After all eight actions are resolved (4 per player), whoever has more cards of a geisha's color wins that geisha's favor. The player who wins 4 of 7 geisha by count, OR earns 11 of the 24 total points (geisha values sum), wins the round and the game.

Turn Structure and State

• BGA tutorial is present; useful for exact turn flow and implementation gotchas.
• BGG description anchor: Welcome to the most famed Geisha street in the old capital, Hanamikoji. Geishas are elegant and graceful women who are skilled in art, music, dance, and a variety of performances and ceremonies. Greatly respected and adored, Geishas are masters of entertainment. In Hanamikoji, two players compete to earn the favor of seven illustrious Geishas by collecting each Geisha’s preferred performance item. With [...]

Win Condition and Arc

Win the round by controlling 4+ geisha or 11+ points worth of geisha. First player to win a set number of rounds (typically best of 3) wins the game. Each round is played with the full 21-card deck reshuffled; geisha favor resets each round. The arc within a round is a tight 8-action puzzle in which each player is simultaneously trying to force unfavorable offers onto the opponent while protecting their own core geisha targets.

Decision Primitives

BGG mechanisms: Area Majority / Influence, Force Commitment, Hand Management, I Cut, You Choose, Open Drafting, Race

Memory-derived primitives:

• Hand management under perfect information (all played cards visible after actions)
• Forced selection mechanics (opponent chooses from your offers — all four actions are offer-based)
• Simultaneous hidden-action sequencing (action order within round creates bluffing space)
• Point-threshold dual win condition
• Set majority (geisha favor by card count per color)

v4 controlled primitives: bidding_with_secret_stake, region_majority, _other:i_cut_you_choose, hand_management_under_draw, attrition_clock

Top iOS archetype fits: snap 6.6, balatro 4.3, cozy 4.3.

Why It Is Fun

The game is a tight, elegant information puzzle. All four actions give the opponent choice — nothing is ever purely yours until the end of the round — which creates constant anxiety about what the opponent will take. The asymmetric card-count distribution (some geisha have more cards) means high-value geisha are also more contested. Games are fast (15 min) and deeply replayable because the action sequencing creates genuine bluffing tension.

• One of my favorite two player games - so easy to learn but so strategic at the same time! Beautiful artwork and interesting decisions
• Another simple but nice deduction game which forces players to think in any way but linearly. Having a card in hand does not always mean owning it. Plus, the art looks nice.
• Masterclass in minimalist game design. There's such a rich game in this tiny box which works with very few components and even less actions.

Friction and Failure Modes

• Treat Sonnet-memory edge rules as draft until confirmed by manual, BGA, or transcript.

Translation and Design Hooks

• Use this card to ask: which primitive carries the fun if theme/licensing is removed?
• For iOS, look for short-session compression, clear state visualization, and a digital-only twist.
• For new tabletop design, look for the tension source and decide whether to preserve or invert it.

Edge Rules and Gotchas

• The Secret (discard 2 face-down) action is the only action that removes cards from potential scoring; correctly reading which 2 cards to hide is the highest-skill decision
• If a player is winning a geisha and the opponent has played out all their action markers, the remaining geisha are safe — tracking remaining actions is crucial
• Tie in card count for a geisha: the geisha keeps the same favor as the previous round (or is neutral at round start, meaning neither player wins it on a tie)
• The Competition action (2v2 pairs) is the most information-dense: optimal play requires knowing which geisha the opponent is most desperate to win
• Draw order is deterministic — each player draws from the same shuffled deck, so the total card distribution is known, enabling exact probability tracking late in rounds
