Binario (also called Takuzu or binary puzzle) fills a grid with two symbols. No row or column may have three of the same symbol in a row, every line holds as many of each, and no two lines may be identical.
How this mode works
Tap a cell to cycle ● → ○ → blank.
Every line needs as many ● as ○, and no two lines may match.
Tips to get better
Two identical symbols side by side force the opposite symbol on both ends.
A gap between two identical symbols must be the other symbol.
Count: once a line has half its cells of one symbol, the rest are the other.
Use the last rule near the end — two nearly finished lines can not end up identical.
