怎么玩黑白棋？
黑白棋（英文名 Reversi，品牌名 Othello）由英国人于 1883 年发明。规则简洁而策略深邃：双方轮流在 8×8 棋盘上落子，落子必须能在直线方向上把对方的棋子夹在自己的两颗棋子之间，被夹住的全部翻面变为己方颜色。当棋盘填满或双方均无处落子时游戏结束，棋子多的一方获胜。
操作方式
- 轻点或点击棋盘上高亮的合法落子点即可落子；灰色小圆点表示当前可落子的位置。
策略要点
- 优先争夺四个角。角位棋子永远不会被翻转，一旦占据就固定为己方。这是黑白棋最重要的位置。
- 不要贪图翻多。一次翻转大量棋子看起来很爽，但会给对手更多合法落子点，让对方反超。
- 避免靠近角位的 C 格和 X 格。落到角位相邻的格子往往会送给对方抢角的机会。
常见问题
什么算合法落子？
落子后必须在至少一个方向上夹住对方棋子。不满足此条件的位置无法落子。
没有合法落子怎么办？
自动跳过，由对方继续。双方均无处落子时游戏结束，棋多者胜。
AI 强度如何？
中等难度：贪心策略 + 位置权重，优先角位。有一定挑战性但并非无敌。
How to play Reversi
Reversi (brand name Othello) was invented in London in 1883. You place a disc to sandwich at least one opponent disc in a straight line between your new disc and another of yours — all sandwiched discs flip to your colour. The board fills, and whoever has more discs wins.
Controls
- Tap or click any highlighted legal move (shown as a faint dot).
Strategy
- Corners are king. Corner pieces can never be flipped — seize them whenever you can.
- Don't chase big flips. Flipping many pieces early gives the opponent more legal moves to bounce back.
- Avoid C- and X-squares. The cells next to corners are dangerous — they often hand the corner to the opponent.
FAQ
What is a legal move?
Any placement that sandwiches at least one opponent piece in a straight line.
What if I have no legal moves?
Your turn is skipped. When neither player can move, the game ends — more discs wins.
How strong is the AI?
Medium: greedy scoring with positional weights, prioritising corners. Challenging but beatable.
