GridNerd: Nonogram Puzzles

One puzzle. Every day. One hidden picture waiting to be revealed. GridNerd is a daily nonogram puzzle game. Use the number clues to fill the right cells, and a hidden pixel art picture appears. Every puzzle has exactly one solution, so it is pure logic. No guessing required. HOW IT PLAYS Tap a cell to fill it. Touch and hold to mark it empty. The numbers on each row and column tell you how many cells to fill and in what groups. Complete a row correctly and its clues light up. THE DAILY PUZZLE A brand new puzzle arrives every morning. Solve it to grow your daily streak, and restore your streak with a short ad if you miss a day. A countdown always shows when the next puzzle unlocks. 900 BONUS PUZZLES The Puzzle Library holds 900 extra grids across 4 tiers: Easy 5x5, Medium 10x10, Hard 15x15, and Extra Hard 20x20. Play at your own pace with star ratings, best times, and sequential unlocks. The first level of every tier is free. HELP WHEN STUCK Earn coins by solving puzzles and watching optional ads.
