About Binario: Takuzu
Binario is a Takuzu puzzle in which you fill a square board with 0 and 1. Every row and column must contain equal numbers of both symbols. Three identical symbols cannot appear consecutively, and no two rows or two columns may match. The initial clues are fixed, and every generated puzzle has exactly one solution. Choose a 6×6 board for a smaller puzzle or explore the 8×8 size. Free play creates new puzzles, while the daily challenge uses the same seed for everyone on each UTC date and board size. Actual difficulty varies between puzzles; board size is not a calibrated difficulty rating. Play with a mouse, keyboard or touch screen. Hints, undo and rule checking are available and mark your result as assisted. Games and personal records are saved locally. You can continue a saved puzzle without an account, and the global ranking is currently disabled. Sound, high contrast and reduced motion can be adjusted in settings.
