目標
你與三位電腦玩家各拿 13 張牌，最先把手牌出完的人贏得這一局。
牌的大小
- 點數：3 < 4 < … < 10 < J < Q < K < A < 2
- 花色（台灣規則）：♠ 黑桃 > ♥ 紅心 > ♦ 方塊 > ♣ 梅花
- 單張先比點數，點數相同再比花色，所以 ♠2 最大、♣3 最小
牌型
- 單張、對子（比較大的那張決定大小）、三條
- 五張牌型由小到大：順子 < 同花 < 葫蘆 < 鐵支 < 同花順
- 順子：五張連續點數，不能繞過 2（J-Q-K-A-2 不算）。大小：3-4-5-6-7 最小 … 10-J-Q-K-A < A-2-3-4-5 < 2-3-4-5-6 最大；同樣的順子比最大那張的花色（A2345、23456 比那張 2）
- 同花：五張同花色，比最大的那張（先比點數再比花色）
- 葫蘆：三條＋一對，比三條的點數
- 鐵支：四張同點數＋任一張，比四張的點數
- 同花順：同花色的順子，比法同順子
出牌
- 拿到 ♣3 的人先出，第一手必須包含 ♣3
- 之後依序（逆時針：你 → 右 → 上 → 左）出相同牌型且更大的牌，或選擇「不出」
- 五張牌型之間可以互壓，例如葫蘆壓順子
- 炸彈：鐵支與同花順可以壓任何單張、對子或三條（包括 2）
- 其他三人都不出時，最後出牌的人可以自由出任何牌型
計分
- 有人出完牌就結束這局，其他人依剩下的張數付分給贏家
- 剩 1–9 張：每張 1 分；剩 10–12 張：×2；13 張一張都沒出：×3
- 積分會一局一局累積，直到你按「重新開始積分」。最高紀錄記錄你累積到的最高分
- 牌局進行中重新整理會接續同一局
Goal
You and three computer players get 13 cards each. The first player to empty their hand wins the round.
Card order
- Ranks: 3 < 4 < … < 10 < J < Q < K < A < 2
- Suits (Taiwan rules): ♠ spades > ♥ hearts > ♦ diamonds > ♣ clubs
- Singles compare rank first, then suit, so ♠2 is the highest card and ♣3 the lowest
Plays
- Single, Pair (its higher card decides), Triple
- Five-card hands, low to high: Straight < Flush < Full House < Four of a Kind < Straight Flush
- Straight: five ranks in a row, no wrapping past the 2 (J-Q-K-A-2 is not a straight). Order: 3-4-5-6-7 lowest … 10-J-Q-K-A < A-2-3-4-5 < 2-3-4-5-6 highest. Equal straights compare the suit of the top card (the 2 in A2345 and 23456)
- Flush: five of one suit, compared by its highest card (rank, then suit)
- Full House: a triple plus a pair, compared by the triple
- Four of a Kind: four of a rank plus any card, compared by the four
- Straight Flush: a straight in one suit, compared like a straight
Play
- Whoever holds ♣3 leads, and the first play must include ♣3
- Play goes counter-clockwise (you, right, top, left). Each player must play the same type but higher, or Pass
- Any five-card hand beats a lower five-card hand (e.g. a Full House beats a Straight)
- Bombs: Four of a Kind and Straight Flush can also beat any single, pair or triple (2s included)
- When the other three all pass, the last player to play leads anything
Scoring
- The round ends when someone runs out of cards. Every other player pays the winner for the cards they still hold
- 1 to 9 cards left: 1 point each. 10 to 12 cards: x2. All 13 cards (never played): x3
- Points carry over round after round until you press New Session. Best is the highest session total you reach
- Refreshing mid-round resumes the same round
