I am loving 0hh1 but I got bored by the largest grid 12x12. Are there similar games but with much larger grids?
Unruly offers the same game principle with custom parameters
Width, Height Size of grid in squares. (Note that the rules of the game require both the width and height to be even numbers.) Difficulty Controls the difficulty of the generated puzzle. Unique rows and columns If enabled, no two rows are permitted to have exactly the same pattern, and likewise columns. (A row and a column can match, though.)
On the website, go to
Type -> Custom and enter your preferred grid size. Note that you also need to tick the checkbox
Unique rows and columns if you want exactly the same rules as in 0hh1.
The generation takes a very long time once you cross the ~24x24 mark.
0h h1 is just one example of a Takuzu puzzle, so searching for Takuzus will broaden your search. For example, here is a 16x16 Binary Puzzle, and here is a 20x20 Binairo. The rules are identical; the only difference is what is used to fill in the cells (red vs. blue, black vs white, 0 vs 1).
