Every picture starts as a wall of numbers. Read the clues, fill the grid, and watch the image emerge — one deduced square at a time.

GRIDGRAMS takes the classic nonogram formula and builds it out in every direction: big boards, full-color puzzles, and giant multi-part pictures you conquer section by section.

175+ Hand-Crafted Puzzles

• Five classic sizes — 5x5 through 25x25

• Colored nonograms — palettes of up to 16 colors

• Mega-Grams — massive pictures split into a grid of boards. Solve each section on its own and watch the full artwork assemble tile by tile.

Logic, Not Guesswork

Clues turn green once satisfied — instant feedback that you're on the right track, even on 60-cell lines where brute force would be hopeless. When you're truly stuck, two earnable abilities — Random Reveal and Reveal Selection — offer a nudge. Clear more puzzles to unlock more uses.

Play It Your Way

• Mouse: click to fill, right-click to mark, and drag-paint whole runs — with an optional straight-line mode that keeps fast strokes straight.

• Keyboard and controller: fully rebindable, with Xbox, PlayStation, and Nintendo controller support.

• Zoom into the big boards to easily see on lower resolutions.

• Steam Deck ready out of the box.

Four Distinct Styles

Solve on Classic blueprint blue, jack into Cyberdeck green-on-black hacker digital rain backdrops, relax on Goldleaf's gold-on-slate, or drift with Amethyst's wind-blown skies. Customize your square fill animation and fully tune your cursor to make the grid yours.

Built to Respect Your Time

Leave any board mid-solve and pick it up exactly where you left it — cells, cursor, and ability uses intact. Best clear times are recorded per picture, achievements track everything from your first solve to flawless 25x25 runs, and progress syncs through Steam Cloud.

The numbers are waiting. The pictures are hiding. Start solving.
