Tintout
Slide every block home.
Tintout is a calm, clever colour puzzle. Slide each block out through the gate of its own colour. Clear the board to win.
Hundreds of levels, each one proven solvable before it ships, a daily challenge, and new ideas every few worlds: locks, ice, one-way tiles, paint and switching gates.
Fair by design: you are stuck because the puzzle is hard, never because the game wants money. A colour-blind mode gives every colour its own shape.
