How to play

• Your area starts as the top-left cell and everything of the same colour joined to it.
• Choosing a colour repaints your whole area, absorbing any neighbours of that colour.
• The board is cleared when every cell belongs to your area.
• The move limit is generous but not infinite.
• Par is the number of moves a good line needs on this board.

Tips

• Grow towards the largest untouched blocks, not the nearest ones.
• Do not chase a single stray cell: it will be absorbed later anyway.
• When two colours are equally tempting, take the one that reaches further from the corner.
• The last two or three moves are usually forced — plan the middle of the game, not the end.
