目標
你與三位電腦各拿 13 張牌，排成三墩：頭墩 3 張、中墩 5 張、尾墩 5 張，再和每位對手逐墩比大小。
牌型大小（由小到大）
散牌 < 一對 < 兩對 < 三條 < 順子 < 同花 < 葫蘆 < 鐵支 < 同花順
- 頭墩只有 3 張，只會是散牌、一對或三條
- A 最大，也可當 1 組成 A-2-3-4-5（最小的順子）；不能 Q-K-A-2-3 繞圈
- 同牌型依序比點數（對子先比對子、再比單張），不比花色；完全相同算平手
相公
必須 尾墩 ≥ 中墩 ≥ 頭墩。排錯就是相公：對每位沒相公的對手三墩全輸，而且算被打槍。畫面會即時提示。
計分（與每位對手各算一次）
- 每墩贏 +1、輸 −1、平手 0
- 獲勝那墩若是以下牌型，改記較高分：頭墩三條 3 分；中墩葫蘆 2 分、中墩鐵支 8 分、中墩同花順 10 分；尾墩鐵支 4 分、尾墩同花順 5 分
- 打槍：對某位對手三墩全贏，與他的分數 ×2
- 全壘打：同時打槍另外三人，與每人的分數再 ×2（共 ×4）
- 四人分數加總一定是 0
特殊牌型（自動偵測）
拿到特殊牌型時會跳出提示，可選擇宣告（不用排牌，直接贏一般牌）或照常排牌。電腦拿到一定宣告。
- 一條龍：A 到 K 各一張，向每位對手收 13 分
- 三同花：三墩都能各自同花，收 3 分
- 三順子：三墩都能各自成順（頭墩 3 張連號），收 3 分
- 六對半：六個對子加一張單牌（鐵支算兩對），收 3 分
- 大小：一條龍 > 三同花 > 三順子 > 六對半；特殊牌型互比時大的收自己的分，相同則平手；特殊牌型不算打槍
分數紀錄
本場總分從 0 開始累計，「最佳紀錄」是歷來最高的本場總分。比牌前重新整理會接續同一副牌；按「重新開場」把總分歸零。
Goal
You and three computer players get 13 cards each. Split them into three rows: Front 3 cards, Middle 5, Back 5, then compare row by row with every opponent.
Hand ranks (low to high)
High Card < Pair < Two Pair < Three of a Kind < Straight < Flush < Full House < Four of a Kind < Straight Flush
- The 3-card Front can only be High Card, Pair or Three of a Kind
- Aces are high, or low in A-2-3-4-5 (the lowest straight). No wrap-around like Q-K-A-2-3
- Equal ranks compare card values in order (pair first, then kickers); suits never matter and an exact match is a tie
Foul
Back must be at least as strong as Middle, and Middle at least as strong as Front. Otherwise the hand fouls: it loses all three rows to every opponent who did not foul, and that counts as being swept. A live indicator warns you.
Scoring (against each opponent separately)
- Each row: win +1, lose −1, tie 0
- A winning row is worth more with these hands: Front Three of a Kind 3 points. Middle Full House 2, Middle Four of a Kind 8, Middle Straight Flush 10. Back Four of a Kind 4, Back Straight Flush 5
- Sweep: win all three rows against one opponent and the points against them double
- Grand Slam: sweep all three opponents and each of those totals doubles again (×4 in all)
- The four players' points always add up to 0
Special hands (auto-detected)
If you are dealt one, a prompt lets you declare it (no arranging, it beats every normal hand) or play normally. Computer players always declare.
- Dragon: one of every rank A to K, wins 13 from each opponent
- Three Flushes: all three rows can each be a flush, wins 3
- Three Straights: all three rows can each be a straight (the Front a 3-card run), wins 3
- Six Pairs: six pairs plus a single (four of a kind counts as two pairs), wins 3
- Order: Dragon > Three Flushes > Three Straights > Six Pairs. Between two specials the higher one wins its own points, equal ones tie. Specials never count as sweeps
