What's in the game · version 1.19
- Every puzzle has exactly one solution, and it can be reached by logic alone. No guessing.
- Four sizes: 5×5, 7×7, 9×9 and 11×11; the big grids open as you play.
- Difficulty rises with you, so the puzzles keep up as you get better.
- A daily, a weekly and a monthly challenge, the same board for everyone, with a daily streak to keep.
- Five colour themes: Classic, Sakura, Lagoon, Meadow and Night.
- Pencil dots: long-press a cell to mark it while you think.
- Expert mode: no colours until the board is full.
- Hints that point at your mistake, not just the next piece.
- Best times for every size and difficulty, a stats screen and 14 goals to reach.
- Playable with a keyboard and a screen reader, not only by touch.
- Plays offline, in English, Slovak, Arabic, French, Spanish and German.
Quiet by design: ink on paper, soft sounds, optional calm music, nothing flashing at you.
