About this game

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.

FILL AN ALBUM, PAGE BY PAGE
• 7 albums and 168 hand-made pictures: harbours, rooftops, kitchen tables, workshops, botanicals, journeys and field notes
• Grids from 10×10 up to 25×25
• A new daily puzzle every day, marked with a dated postmark
• Classic mode: endless logic-only grids in four sizes and four difficulty levels, up to Expert

NO LIVES. NO RUSH.
• Mistakes never cost you anything. Undo and redo as much as you like
• Optional mistake check by line, or by cell
• Line lens shows the clues for the row and column you are working on
• Pinch to zoom on big grids, with clues that stay in view
• Auto-cross finished lines, left-handed layout, timer hidden by default

EASY ON THE EYES
• Light and dark themes, large text support, screen reader labels
• Plays fully offline. Your progress stays on your device, with backup to a file you choose

FREE TO PLAY
Gridwright is free and shows ads: one small banner while you play, an optional ad for a hint, and an occasional full-screen ad only after you finish a stamp — never in the middle of a puzzle. A one-time "Remove ads" purchase turns all ads off and gives you free hints every day.
