Solve the grid. Keep the stamp.
Gridwright is a calm picture logic puzzle. The numbers on each row and column tell you which squares to fill. Work them out, and a hidden picture appears — then it is pressed into a stamp and pasted into your album.
EVERY PUZZLE SOLVES BY LOGIC
Every puzzle in Gridwright has exactly one answer and can be solved without guessing. We check each one with a solver before it ships.
