Nonogram Logic Puzzle: Nibgrid

Nibgrid is a nonogram game where every puzzle can be solved by logic alone. You never have to guess. Nonograms (also called hanjie, griddlers or picture cross puzzles) are grids with numbers along the edges. Each number tells you how many squares in that row or column are filled, in order. Work out which squares to fill and a hidden picture appears. NO GUESSING, EVER Many nonogram apps make puzzles at random and only check that some solution exists, so you end up stuck and guessing. Every Nibgrid puzzle is checked by a solver that uses line-by-line logic only, and only puzzles it can finish make it into the game. That also means every puzzle has exactly one solution. HAND-PICKED PICTURES Every puzzle was chosen by a person, not a generator, so the picture you uncover actually looks like something. • 10×10 puzzles to learn and relax with • 15×15 puzzles once you are ready for more • New puzzles unlock as you solve A DAILY PUZZLE A fresh puzzle every day, with a streak to keep. Turn on an optional morning reminder so you never miss one. HINTS THAT TEACH Stuck? A hint fills in one line and tells you why, so you learn the technique instead of just getting the answer. If you have made a mistake, the hint clears it first. Three free hints a day, then more with a short video. MADE FOR CALM PLAY • Fill and cross modes; drag to fill a whole line • Unlimited undo and redo • Your board is saved as you play • Four colour schemes, including a dark one • Achievements to collect • A short guide for first-time players • Plays in 13 languages Nibgrid is free to play with ads. A one-time purchase removes the ads between puzzles; the optional hint videos stay available if you want them.
