Test your brainpower with the latest and greatest logic puzzle from Crystal Squid Games!
All you have to do is place the 9 numbers, letters, animals or gems in the grid so that there is only one of each in a single row, column, or 3×3 ‘cell’. How hard can that be, eh?
With 3 new puzzles every day, and great features & graphics this game doesn’t just tease the brain, it shows it who’s the boss!Updates11th Dec 09: Regular/Expert no longer show right/wrong moves. Placing duplicate numbers still get shown in red. Balanced puzzle difficulties better (some expert were a lot easier than others!). Added some keyboard shortcuts.
