About the Game

If you’re into clever puzzles that get your brain going, 0h n0 by Q42 is worth a look. It’s a bright and minimal logic game where you fill in a grid by figuring out which dots are blue and which are red, based on some neat little rules. No guesswork here—just pure thinking and a lot of “Aha!” moments. This one’s the perfect choice whether you want to zone out or test your mental reflexes for a personal record.

Game Features

• Simple Rules, Seriously Deep Puzzles
  You’re working with blue and red dots. Blue dots “see” along their row and column, but those pesky red dots block their view. The number on a blue dot tells you how many others it can spot, so every move feels like untangling a little mystery.

• Loads of Grid Sizes
  Play on whatever size board you’re in the mood for, from a bite-sized 4×4 up to a tricky 9×9. Fancy a middle ground? Boards like 5×5 or 7×7 hit that sweet spot. There’s no shortage of combinations to play around with.
