Pattern Recognition

In every round of Pattern Recognition, all the tiles in the grid are identical — except one. Your job is to find it. Early on the difference is obvious: a different shape or a half-turn. As you progress, it becomes a subtle rotation, a mirror image, a slight change of size or a small shift in colour.

It is a quick, satisfying test of visual attention, and a good warm-up before longer puzzles.

1. Look at the grid and find the tile that differs from all the others.
2. Click or tap it. A correct choice moves you to the next round.
3. Each level has eight rounds and you have three lives. A wrong tile costs a life.
4. Clear all eight rounds to complete the level. Later levels use larger grids and subtler differences.

• Look at the whole grid with a soft focus first — the odd tile often stands out in peripheral vision.
• Use a reference tile. Compare tiles against one chosen tile rather than against each other.
• Scan in rows if nothing pops out, so you never check a tile twice.
• Know what can change: shape, rotation, mirror image, size, brightness or hue.
