Pareggio

Pareggio is Takuzu, the binary logic puzzle, made with care. No ads, no lives to lose, no account.

THE RULES IN ONE BREATH Fill the grid with filled and hollow pieces. Never three alike in a row. As many of each in every row and every column. No two rows the same, and no two columns.

TWO FORMS OF THE GAME Classic, and with signs: = between two cells means the same piece, × means different pieces, as in the puzzle made popular in 2024. In Pareggio, the rule against identical rows applies to both forms.

ONE CHALLENGE A DAY Every day a new grid, the same for everyone. 6×6 and Very easy on Monday, 12×12 and Expert on Sunday, with signs on Wednesday and Saturday. Share your time in one tap.

SIZE AND DIFFICULTY, SEPARATELY Elsewhere, Easy means small and Expert means big. In Pareggio you choose the size (6×6 to 12×12, plus 14×14 on iPad) and, on its own, one of five levels. Every grid is rated by the hardest technique it truly requires, and the app names it: "Hard — requires Uniqueness". Every grid has a single solution, reached by logic alone: never a guess.

HINTS THAT TEACH Stuck? Hints come in three steps: where to look, why (the technique), then the answer. If a piece is wrong, the hint says so first. Not keen on that lead? "Another hint" shows a different deduction. You learn the technique instead of being handed the answer.

MADE FOR PLAYING • 80,000 grids, each with a single solution • Tap a cell: empty, filled, hollow • Pieces told apart by their shape, not by colour alone, or 1 and 0 if you prefer; with Pro, also squares, diamonds, stars and five colour sets • Unlimited undo, check on demand, or continuous checking of the rules • No mistake limit: a slip of the finger never costs you the game • iPhone and iPad, portrait and landscape on iPad, with hardware keyboard support • Daily challenge widget, Siri Shortcuts • A techniques guide, with a real example for each, and statistics with no streak to keep up • VoiceOver reads every cell, with the counts of its row and column
