Binairo

Binairo IO is a modern and elegant logic game. Easy to understand, hard to put down. Fill the grid with 0s and 1s by following four simple rules. Quick to play, challenging to master. Each game lasts only a few minutes — perfect for a break, a relaxing moment, or a real brain challenge. The app generates endless grids with four difficulty levels: Easy and Medium are free, while Hard and Extreme are available in the Premium version. Statistics lovers will enjoy tracking their best times, win rates, and flawless games, while advanced players can fine-tune every detail: mask percentage, error detection, sounds, haptics, and more. Every day brings a new Daily Challenge. Complete it, build your winning streak, and unlock exclusive trophies. Optional notifications (disabled by default) can remind you not to miss it. Designed for a smooth, refined experience, Binairo adapts to all your devices — iPhone and iPad, light or dark mode, colored digits, clear and fluid interface. Your progress, streaks, and trophies are synced via iCloud, unless you prefer to keep this device independent. The Premium version (one-time purchase, no subscription, Family Sharing supported) unlocks advanced levels, unlimited hints, and removes all ads — while supporting future app development. The app is available in over 20 languages.
