Nonograms contains simple yet challenging puzzles, in which your goal is to uncover a hidden black and white pattern. The puzzles contain a grid with number clues that tell you how many groups of black squares there are in any given row or column, and how many black squares there are in each group. With this information, and some skillfully applied logic, you can solve the puzzle.
With three difficulty levels, Nonograms can be enjoyed by beginners and experts alike. An optional game clock lets you see how quickly you can solve the puzzles, and you can try to beat your best time for each difficulty level. If you find a puzzle too hard, you can ask for hints or view the solution to that puzzle. Nonograms randomly generates new grids, so it is unlikely that you will ever run out of puzzles to solve.
Nonograms are an enjoyable way to exercise your mind, and if you like sudoku and similar number grid puzzles, you'll love Nonograms.
