The Visual Memory Test measures how many tile positions you can hold in your mind at once. A set of tiles flashes white on a grid; once they fade, you click every one that lit up. Each level adds another tile and the grid gradually grows.
How it works
At the start of each level several tiles flash white simultaneously. After a short display window they fade back to the board, and you click the tiles you remember lighting up. Order does not matter here — you simply need to find them all. Clear a level and the next adds a tile (and eventually a larger grid); click a tile that was not in the pattern and you lose one of your three lives.
What it tests
This is a test of visuospatial working memory — your ability to retain the layout of several items seen at the same moment. It differs from a sequence test, which shows tiles one by one and demands the exact order. Here everything appears at once, so you are storing a snapshot rather than a path.
Tips
Try to take in the whole board as a single image rather than memorising tiles one by one, and look for shapes or clusters the lit tiles form. Staying calm on the larger grids matters most — that is where a hurried guess usually costs a life.
