How to play
Click a card to flip it; you can see at most two at once. Two identical cards stay matched, otherwise they flip back. Match every pair in as few moves and as little time as possible. Cards are shuffled locally, so a refresh starts a new round.
示例与注意事项Example & notes
一个例子A worked example
4×4 共 8 对卡片：翻开两张相同即消除，步数与用时会被记录，用来比较不同翻牌策略。A 4×4 board holds eight pairs: matching two clears them, and move count plus time let you compare strategies.
注意事项Things to watch
- 按固定顺序翻、记住位置，比随机乱翻效率高一倍以上。Flipping in a fixed pattern and memorising positions roughly doubles efficiency.
- 步数比用时更能反映记忆效率，用时短可能只是手快。Move count reflects memory better than time — fast hands are not good memory.
- 8 对以上开始吃短期记忆，难度提升要循序渐进。Beyond eight pairs short-term memory becomes the bottleneck, so raise difficulty gradually.

每局位置是随机的吗？Is the layout random each game?
是，每次重开都重新洗牌，避免记住固定位置。Yes — every restart shuffles, so fixed positions cannot be memorised.
