使用方法
- Choose a board size: 4×3 (6 pairs), 4×4 (8 pairs) or 6×5 (15 pairs).
- Click cards to flip them and find the matching emoji pairs. Flipping two cards counts as one move.
- Matched pairs stay face up; unmatched cards flip back.
- Match them all to see your moves and time. The best (fewest moves) per size is saved.
注意事项
The layout is shuffled with the Web Crypto API. The timer starts when you flip the first card. Best results are stored only in this browser's localStorage (key: yt-memorygame-best).
常见问题
- What if emoji render poorly on my device?
- Emoji appearance depends on your device and OS fonts. Even if a glyph looks different from another platform, identical emoji always form a pair.
