Play Takuzu grids from 6x6 to 12x12 at four levels, as many as you like. The level is the hardest rule-combination the grid needs, not the size: a Hard 8x8 needs the no-twins rule, while an Easy 12x12 falls to pairs and counting.
This puzzle
Loading ยท the grid and its level
(a small spoiler)
Checked: exactly one solution, reachable by logic. The level is the hardest technique our solver needed, not the grid size.
Settings
Rule breaks (three in a row) always show in red. "Show mistakes" also marks cells that disagree with the solution.
Size, level and time
Every extra row adds two lines to fill, so big grids take longer even at the same level. The harder levels need fewer given circles on average, because the removal stops as soon as the next deduction would need a technique above the level.
