Factor Grid

Factor Grid is a rectangle-division logic puzzle wrapped in a neon arcade cabinet. Every number on the board tells you the exact area of the rectangle that must cover it — no more, no less. Draw carefully: every clue gets exactly one rectangle, every rectangle gets exactly one clue, and the whole grid must be covered edge to edge.

What's inside:

• 300 handcrafted puzzles across six difficulty tiers, from Beginner to Master — every single one verified to have exactly one solution
• 5-star rating system that scales with puzzle size, so a clean solve on a tough grid actually means something
• 25 achievements across Bronze, Silver, Gold, and Platinum tiers
• Full keyboard support — play entirely with arrow keys, Space/Enter, and shortcuts, or just drag with mouse/touch
• Original music and sound — five shuffled gameplay tracks so no two sessions feel the same, plus a dedicated menu theme
• Per-level best times, perfect-category crowns, and a level select that actually shows your progress

No ads, no timers forcing your hand, no paywalls between you and level 300. Just you, the grid, and the satisfying click of a rectangle locking into place.
