🧠 方块记忆Visual Memory
在线方块记忆测试：网格里会有几个方块短暂亮起，记住它们的位置，等熄灭后把它们一个不差地点出来。每过一关多亮一个方块，网格也会从 3×3 逐渐变大到 7×7。每关最多点错 3 次，共 3 条命，看看你的视觉空间记忆能撑到第几关。Visual Memory test online: a few tiles in the grid flash briefly — remember where they were and tap them all once they go dark. Each level lights one more tile, and the grid grows from 3×3 up to 7×7. You get three misses per level and three lives in total. How far can your visual-spatial memory take you?
方块亮起时不要点，等它们暗下去再点；同一关点错 3 次会失去一条命并重来本关。Don't tap while tiles are lit — wait until they go dark. Three misses in a level costs a life and restarts the level.
玩法说明与常见问题How to play & FAQ
「方块记忆」怎么玩？How do I play Visual Memory?
第 1 关亮 3 个方块，之后每关多 1 个。记忆技巧：不要一个一个地记，而是把亮起的方块看成一个整体“图形”，比如一条斜线、一个 L 形或几个角；方块多了以后可以按行分组记。一般人能到第 8～10 关，坚持练习会明显提高。Level 1 lights three tiles and each level adds one. Memory tip: don't memorise tiles one by one — see the lit tiles as a single shape such as a diagonal, an L or a set of corners; with more tiles, group them by row. Most people reach level 8–10, and practice helps noticeably.
这个测试能说明什么？What does this test measure?
它主要考察视觉空间工作记忆，也就是短时间内记住“东西在哪里”的能力，仅供娱乐和练习参考。Mainly visual-spatial working memory — remembering where things are over a short time. It's for fun and practice only.
方块亮起时可以点吗？Can I tap while the tiles are lit?
不行，亮起阶段网格是锁定的，点了不会有反应；等方块全部暗下去以后再开始点。No — the grid is locked while tiles are lit. Wait until they all go dark, then start tapping.
