Какуро

Kakuro is a classic numerical puzzle game originally from Japan. The field is divided into blocks, each with a specified amount. The task is to arrange the numbers from 1 to 9 so that the block gives the required amount, and the numbers inside the block are not repeated. Unlike Sudoku, not only positions work here, but also arithmetic: the sum of 6 out of three cells is collected in the only way — 1, 2 and 3. At the intersections of such blocks, the whole logic of the solution is born. 180 levels in five sets: from compact 5×5 grids for exploring to spacious 9×9, where there are four times as many cells. Each puzzle has exactly one solution and is solved by pure logic, without guessing. Plus a separate puzzle of the day, a new one every day. There is a note mode, undo progress, hints and error checking. The progress is saved automatically, including between devices.
