Select up to 5 cards, then Play. Cards of the same rank (number) make hands, and higher ranks score more. Played cards outside the hand are burnt for the run, so swap unwanted cards with Discard & Draw.
Score = points × multiplier. Cards marked CTR (Counter: their element beats the enemy's) raise the multiplier. Play 3+ cards of one element for an Element Skill.
Your score is your damage. Drain the enemy's HP to reach dawn. Every few plays, the enemy's move hits your HP. At the Dawn Shop, spend coins on Charms and level up hands, then slay the Oni of the eighth night. Details under “Hands”.

Cards whose element beats the enemy's are marked CTR (Counter). Each scoring Counter card gives +1 multiplier. Only the scoring cards of the hand count (for a Pair, just those two cards).
Score = points × multiplier. Each is added up on its own, then they are multiplied. Points = the hand's base points (Pair 10, Three of a Kind 30…) + rank × 2 for every card used in the hand (not just the highest). Multiplier = the hand's base multiplier (High Card 1, Pair 2, Two Pair 3…) + 1 per Counter card. Example: a Pair of 8s with 2 Counter cards → points 10+16+16 = 42, multiplier 2+2 = 4 → 168. The same Pair with no Counter cards: 42×2 = 84.
Play the same hand type as your previous play (e.g. any Pair after a Pair) and the chain count is added to the multiplier (2nd play +1, 3rd +2… up to +4). A different hand type breaks it. Chains carry over between nights, so the first play of a night can continue the last night's hand. It's the fork between repeating a hand you've leveled with Star Cards and switching to a bigger hand.
Your deck is built once at the start of a run and cycles through all the nights. Played and discarded cards go to the discard pile, and when the deck runs out they are reshuffled back in. Your hand also stays at dawn, so a half-built hand can carry into the next night. Cards bought as Offerings are in your hand at the start of the next night (glowing frame; any cards over your hand size, lowest rank first, go to the deck). The rank 10 from a "Double" goes on top of the deck (your next draw). "Thin" removes cards from your deck right away. Played cards that aren't part of the hand are burnt and never return this run (playing leftovers as a dump shrinks your deck; buy more with Offerings). Tap "Deck / Discard pile" at the bottom of the screen to see where every card is now.
Discard the selected cards and draw the same number from your deck, 2 times per night (Charms and Preparations add more). It doesn't use a Play. Use it to cut cards that don't fit and build big hands like Three of a Kind, Full House or Flush. From Night 3 a Pair won't reach the target, so plan on discarding to build.
If 3 or more of the cards you play share an element, that element's skill triggers (they don't need to be scoring cards; each skill works once per night, twice with Skill Mastery; Mend, Clarity and Groundwork don't trigger on the play that defeats the enemy). Fire · Embers = +3 multiplier on this play / Water · Clarity = Sealed cards score on your next play / Wood · Mend = +10 HP / Metal · Hone = each Counter card on this play gives +1 more multiplier / Earth · Groundwork = delays the enemy's move by 1 play
敵の技
敵は数手ごとに技を仕掛けてくる。次の技までの手数は敵の下の「あと N 手」（押すと図鑑）。店の鉄壁のお守りで一度だけ防げる。技は敵の五行で決まる：火「焦がす」＝手札1枚を焼く（この周回では戻らない）／水「流す」＝手札をすべて流して引き直させる／木「絡める」＝次の一手は札4枚まで／金「削る」＝次の一手の倍率−2／土「埋める」＝敵の最大体力＋15％。第一・二夜の澱だけは「呑む」＝手札2枚を封じる（次の一手は0点・捨てれば消える）。技が出るたびに敵の力ぶん体力を失う（澱8・逆しま12・鬼25、五行と難易度で上下）。土の地固めで遅らせ、木の癒しで取り返す
Enemies strike every few plays. The plays left until the next move are shown under the enemy as "in N plays" (tap it for the bestiary). The shop's Iron Ward blocks one move. The move depends on the enemy's element: Fire: Scorch = burns 1 card in your hand (gone for this run) / Water: Wash Away = washes away your whole hand and makes you redraw / Wood: Entangle = your next play is limited to 4 cards / Metal: Whittle = −2 multiplier on your next play / Earth: Bury = enemy max HP +15%. Only the Dregs of Nights 1–2 use Swallow: seals 2 cards in your hand (they score 0 on your next play; discarding clears them). Every move also costs you HP equal to the enemy's Power (Dregs 8, Sakashima 12, Oni 25, adjusted by element and difficulty). Delay moves with Earth's Groundwork and win HP back with Wood's Mend.
When the Oni of the eighth night drops to half HP or less, it bares its fangs and the Counter cycle reverses (the CTR mark moves to a different element, so the Counter cards you saved for the first half stop working). On Hard its move also becomes "Devour" (devours 1 Play). On Easy it never bares its fangs.
You start with 100. Over the eight nights, HP comes back only from Wood's Mend (+10) and encounters between nights. Enemy moves cost HP equal to their Power. A night doesn't end until the enemy falls. If you run out of Plays, you take a heavy blow of "(enemy HP left ÷ max HP) × Power × 3" (min 5), your Plays and Discards are restored, and the fight goes on against the same enemy. At 0 HP, the night swallows you.
Charms = boosts for the rest of this run (up to 5; when full, the oldest is let go) / Star Cards = level up a hand, growing its points and multiplier / Talismans = thin out your deck or add rank 10s / Iron Ward = blocks the enemy's move once next night (check the next enemy's move before buying). Before the shop, an encounter between nights may appear (up to 3 per run; take it or pass).
Curses are brought by enemies; your plays never cause them. On Normal, about half of the Sakashima carry one from Night 3 (No [Element] / Cramped / No Discards). The Oni of the Eclipse Night always has one (Once Only / Low Cut / Waxing Moon). The Dawn Shop shows the next enemy and its Curse, so buy to match. "Sealed" cards (gray, marked SEAL) still count for hands but score 0. They come from No [Element], Low Cut and Swallow.
Every run earns Moon Shards (nights reached × the difficulty's multiplier, plus a bonus for slaying the Oni). Preparations bought with shards stay for all future runs. Opening a "Ledger" adds new Charms to the shop.
