How to play
  1. Read the examples. Each one shows a grid before and after. The same hidden rule was applied to every one of them.
  2. Name the rule. On Easy it is always one plain step — something like "rotate it" or "swap the colours".
  3. Build the answer. The grid already opens at the size the answer needs — the toolbar tells you what that is. Pick a colour, then click or drag to paint. Copy input fills it from the test grid, handy when the answer is the same shape.
  4. Submit. Three attempts and five minutes each. Whoever gets it right in the least time wins.

The digits 0–9 are just colour names, and 0 is the background. Your answer has to match exactly — every cell, and the right size. Full guide →
