Quiet Puzzle Notebook is here: ad-free logic puzzles you buy once.
Nonograms and loop puzzles solved by logic, plus a daily puzzle and stamp card.
Quiet Puzzle Notebook is a quiet logic-puzzle notebook. Two puzzle types: nonograms (fill cells by the numbers to reveal a picture, 150 puzzles from 5×5 to 15×15) and loop puzzles (connect the dots into one loop; each number counts the lines around it, 120 puzzles from 5×5 to 10×10). Every puzzle is checked to be solvable by logic alone. A new daily puzzle stamps your monthly card; no-hint days get a flower stamp. 15 puzzles of each type and the daily puzzle are included; one in-app purchase unlocks the rest (not a subscription). The app shows no ads and works offline. Three text sizes, sound off by default, gentle haptics, optional mistake highlighting.
