Binairio vs Digital Sudoku ⊞

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.

Digital Sudoku is a Sudoku variant with a twist: every clue isn't a printed number, it's a partial seven-segment display, the kind you'd see on an old calculator or digital clock. Some segments are lit, some aren't — read the pattern, decode the digit, and place it. Once you're solving, it's classic Sudoku logic all the way down. FEATURES • Three board sizes — 4×4, 6×6, and full 9×9 — each with Easy, Medium, and Hard difficulties (9×9 adds Expert). • A new Daily puzzle every day, with its own streak to keep going. • Stuck? Hint walks you through the next logical step instead of just filling in the answer — you still have to place it yourself. • Undo/redo, a mistake-checking readout, and an optional timer you can show or hide. • Achievements and stats track your solves, streaks, and best times per board and difficulty. • Compare your times on a real per-puzzle leaderboard. • Light and dark themes, both designed around the seven-segment look. • Play instantly as a guest — no account or sign-up required. Whether you're decoding your first 4×4 or chasing an Expert 9×9 streak, Digital Sudoku turns a familiar puzzle into something you have to look twice at.
