Goal

Nine tiles, one missing. Every tile has a shape, a colour, a count and a fill, and each feature follows its own rule across the rows. Pick the tile that fits every rule — solve as many grids as you can in 60 seconds.

The rules

• Same — stays the same along each row.
• Each once — each row holds the same three, in a new order.
• Up or down — the count goes up or down by one along the row.
• Add up (level 7+) — the third count = the first + the second.

Every wrong option is off by just one feature — check them all.

Levels and scoring

3 grids solved at a level moves you up; 2 misses in a row move you down. Levels add features that change, move the gap, add fill, and give 6 options. A solved grid earns 4 + 2 × the level, plus 1 for each grid already solved in a row (up to +4). A miss costs 2 + the level.

Fluid Reasoning

Based on Raven's progressive matrices, the best-known test of reasoning: spotting rules you've never been told, and holding several of them in mind at once.
