Complete a balanced binary grid with no triples and no repeated rows or columns.
Guía interactiva
You only need 0 and 1, but the three rules constantly interact. Solve by deduction rather than trial and error.
On an 8×8 board, for example, every row and column finishes with four 0s and four 1s.
Two equal values together force the opposite value beside them; two equal values with a gap force the opposite value in the middle.
Two rows cannot share the same complete sequence, and the same rule applies to columns.
Tap to cycle blank → 0 → 1. You can also type 0 or 1, undo moves, and request a hint if you get stuck.
