About Nonogram #20
This is daily nonograms #20, originally published on Sunday, October 18, 2026. The puzzle uses a 15×15 grid with 59 number clues, and like every puzzle on LogicPuzzle.io it was machine-verified before publication: it has exactly one solution, reachable by pure deduction with no guessing. Difficulty for this date was hard: a weekend-grade challenge and the biggest grid of the week.
Our daily nonograms rotate in difficulty through the week, with small warm-ups on Monday and Tuesday, the standard midweek grid from Wednesday to Friday, and the large weekend editions on Saturday and Sunday. The complete archive keeps every puzzle since launch day, so you can catch up on missed days or replay old favorites in any order.
New to the format? The how to play nonograms guide explains the rules and the solving method in a few minutes. Want more after this one? Unlimited mode generates fresh nonograms on demand, and the printable version of this puzzle comes with the answer sheet at the bottom.
