Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Two forms. One satisfying puzzle. Find the balance with four difficulty levels, helpful hints and a fresh daily challenge. A little puzzle time, whenever you need it. DuoForm is a logic puzzle game built around two simple symbols: filled and hollow circles. Balance each row and column, avoid three matching circles in a row, and make every completed line unique. Follow the extra clues to find your way through. START SMALL, THINK BIG Choose from four difficulty levels, with boards from 4 × 4 to 10 × 10. Keep solving to build your progress in each difficulty. A FRESH DAILY CHALLENGE Come back for a new daily puzzle and build your streak. HINTS THAT EXPLAIN Stuck on a cell? Get a hint that explains what to look for and why the next move works. Place the circle yourself or let the hint fill the cell. PLAY AT YOUR PACE Show or hide the timer, undo and redo moves, or reset the current puzzle. Illustrated rules help you learn as you go. MADE FOR IPHONE AND IPAD Enjoy playful colours, gentle sound effects and optional haptics on supported devices. DuoForm is free to play with occasional ads and optional rewarded ads for extra hints. A one-time Remove Ads purchase removes all ads and unlocks unlimited hints. No subscription or app account is required.
