About Light Up #27
This is daily light up puzzles #27, originally published on Sunday, October 25, 2026. The puzzle uses a 10×10 grid with 21 bulbs to place among 14 numbered walls, 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 light up puzzles 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 light up puzzles guide explains the rules and the solving method in a few minutes. Want more after this one? Unlimited mode generates fresh light up puzzles on demand, and the printable version of this puzzle comes with the answer sheet at the bottom.
