Binary puzzles, if you love puzzling, you should try a binary puzzle. The goal of a binary puzzle is to have the same number of zeros (blue) and ones (green) in every row, and in every column. Each game starts with a grid with a few boxes already filled in. This must be completed further with the following lines: - Every row and every column is unique. - Each row and column contains as many zeros (blue) as ones (green). - There are no more than two neighboring tiles with the same number / color. With thousands of unique puzzles, every game will be different.

Binairio holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Binairio has 121 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 38% of Binairio's written reviews are positive against 83% of Duono's, so the app with the better star average is not the one people write more warmly about.
Binairio ships an update every 3 months, Duono every 2 weeks. The most recent releases landed on October 7, 2026 and October 11, 2026 respectively.
