Nono Blocks Formula is a nonogram logic puzzle game. Use the number clues beside each row and above each column to determine which cells should be dark and which should be crossed out. Each number represents a group of consecutive dark cells. Fill every cell correctly to complete the puzzle. When a row or column matches its clues, the hint numbers turn green. On lower-density levels, the clues may allow more than one possible arrangement. Green means that a row or column fits its clues, but the full grid must still match the puzzle's solution. If all hints are green but the level is not complete, revisit places where more than one arrangement was possible and try a different one. More than 100 levels become progressively more challenging as you advance. Play with simple tap controls on iPhone and iPad, or use a mouse on Mac. Key Features: - Over 100 levels, from beginner to advanced difficulty. - Simple and intuitive controls. - Leaderboards to track your progress and compete with others. - Full VoiceOver support for accessible play. Whether you're new to nonograms or an experienced solver, Nono Blocks Formula offers increasingly challenging logic puzzles as you progress.
