I like the concept of USB Sudoku, but I have mixed feelings. Some puzzles are a breeze, while others drive me crazy. Overall, it can be fun, but I wish there was a better range of difficulty!

I can’t even!! Best Sudoku app ever. I carry it everywhere and love challenging my friends too. The interface is smooth like butter, and the levels just keep getting better. Play this, you won’t regret it!

I was skeptical at first, but boy, was I wrong! USB Sudoku is so addicting, I ended up playing till 2 AM! The hints are super helpful when I’m stuck, and I love the sleek design. Energy drinks and Sudoku? Perfect combo!
