So addictive! The level 3 and 4 puzzles are too easy for me, but level 5 is perfect. Next time I'm going to try a level 6 or 7. It's been great to move up the levels when I'm ready.
These puzzles are a great pastime and moreover, a great workout for the brain!
This app is great! I've been doing Sudoku's for a long time on paper, but I must say that the digital puzzles are much nicer. I especially like the sound effects. Thanks!
