目標
你和 3 位電腦玩家圍成一圈輪流擲 2 顆骰子。桌子中央有一個共用的「積分池」（開局為 0），擲出特定點數的人要把池裡的分數收進自己的「罰分」。20 輪（每人約擲 20 次）後罰分最低的人獲勝，同分並列勝利。
擲骰結果（先判斷對子，再看總和）
- 1+1：你可以指定任何一人（包括自己）吃下整個積分池，池歸 0
- 其他對子（2+2 … 6+6）：反轉出手方向。所以 4+4 算反轉，不算 8 點
- 總和 7：往池裡加分，自己選 +1、+2 或 +3
- 總和 8：吃下池的一半（無條件進位），剩下的留在池裡
- 總和 9：吃下整個池，池歸 0
- 其他點數：安全，換下一位
連續擲骰
- 擲出 8 或 9 並且真的吃到分，同一個人必須再擲一次，直到擲出不會吃分的結果
- 池是 0 時擲出 8/9 等於吃 0 分，視為沒吃分，回合結束
- 7、對子或安全點數都會結束回合（擲出 7 仍要先選加幾分）
回合與方向
- 一場 20 輪，一輪 = 四位玩家各輪到一次；一次輪到 = 從開始擲到結束（含所有連續擲骰）
- 開局隨機決定誰先擲，一開始順時針（你 → 左 → 上 → 右）
- 比賽結束時池裡剩下的分數不計入任何人
- 比賽中重新整理會接續同一局，已擲出的結果不會重來
快捷鍵：Space / Enter = 擲骰，1 / 2 / 3 = 選擇加分。
Goal
You and 3 computer players sit in a circle and take turns rolling 2 dice. A shared points pool sits in the middle (it starts at 0); certain rolls make you move pool points into your own penalty. After 20 rounds (about 20 rolls each) the lowest penalty wins — ties share the win.
Rolls (doubles are checked before sums)
- 1+1: choose any player (yourself included) to take the whole pool; it resets to 0
- Other doubles (2+2 … 6+6): reverse the direction of play — so 4+4 is a reverse, not an 8
- Sum 7: add points to the pool — you pick +1, +2 or +3
- Sum 8: take half the pool (rounded up); the rest stays
- Sum 9: take the whole pool; it resets to 0
- Anything else: safe, play passes on
Re-rolls
- If an 8 or 9 actually gave you points, you must roll again — repeatedly — until a roll gives you nothing
- An 8/9 on an empty pool takes 0 points, counts as no penalty and ends your turn
- A 7, a double or a safe sum ends your turn (after a 7 you still pick the amount)
Turns & direction
- A match is 20 rounds; one round = each of the four players gets one turn; a turn = one player's full sequence of rolls
- A random player starts; play begins clockwise (You → left → top → right)
- Points still in the pool when the match ends go to nobody
- Refreshing mid-match resumes it — rolls already made stay made
Keys: Space / Enter = Roll, 1 / 2 / 3 = pick amount.
