Your goal

Each move repaints the top-left area in a colour you choose, and it swallows every touching square of that colour. Make the whole grid one colour within the move limit shown under the board. The limit comes from the puzzle’s own solver, so it is always achievable.

How to play

Tap any square to repaint the top-left area in that square’s colour. Tapping a square of the current colour does nothing and costs no move. Keyboard: arrows move the cursor, Enter fills with the colour under it. Type sets the size, the number of colours and how many extra moves you get.

Tips

The colour that joins the most squares now is not always best. Look for a colour that opens a path towards the far corner.
Small islands of one colour are cheapest to collect late, when the flood already surrounds them.
With Extra moves at 0 you must match the solver. Try to beat it by one.

Use the board’s Type menu to choose a size or difficulty. Undo and Redo let you explore. Solve reveals the answer when you choose it.
