Whether you know them as numbergrids, nonograms, nonogrids, paint-by-number or any other name (there are dozens!), we’ve got hundreds of thousands of unique puzzles here for you to solve.
There are many online sites offering numbergrid-type puzzles, but far too many of these are computer-generated and either have multiple solutions, or they require the user to guess or use trail-and-error to complete them. Not ours – we’ve engineered every single puzzle on this site so that each has one unique solution, and is solvable using pure logical deduction. Guessing and trial-and-error are never required for any puzzle on this site.Numbergrid Puzzles
