目標
合併同數字方塊,堆出 2048(達成後可繼續玩)。
規則
- 每一步整盤往同方向滑,兩個相同數字相撞會合併成兩倍
- 每回合一格只合併一次(例如 4+4+8 不會直接變 16)
- 每回合會在隨機空格生 2(90%)或 4(10%)
- 棋盤滿且四方向都無法合併 → Game Over
- 沒有勝利封頂,分數可以一直累加

Goal
Merge matching tiles to reach 2048 (keep playing after you hit it).
Rules
- Every move slides the whole board in one direction; matching tiles merge into double
- Each tile merges only once per move (4+4+8 won't collapse into 16 directly)
- After each move a new 2 (90%) or 4 (10%) spawns in a random empty cell
- Board full with no valid merges → Game Over
- No ceiling — keep merging and scoring as long as you can
