For all those casual games out there with flashy graphics and 3D environments, it's nice to just have something with a simple look. Take Mix Sudoku Light Vol. 2, for example, a brand new puzzle release from Conceptis. These games are all about the puzzles and how they stretch your logic skills. There's nothing more satisfying than solving a difficult puzzle so thoroughly that you can develop a strategy to apply to others of that type. Forget the Friday New York Times crossword puzzle, you just solved a Level 6 sudoku puzzle!

Mix Sudoku Light Vol. 2 ups the challenge significantly from the first volume, Mix Sudoku Light. It includes the same variety of puzzles from the everyday classic to the more complex, irregular, or multi sudoku puzzles. The useful gameplay features from before are also there: undo/redo buttons, checking your current answers against the solution, saving your progress and 'penciling in' possibilities. It's the ease of pencil and paper without the hassles of finding an eraser. Whereas Volume 1 had levels ranked 1-3, Volume 2 sports the increasingly difficult levels 4-6 , so be prepared for brow furrowing-induced headaches! If you're new to sudoku or haven't had your hand in the variations before, I'd suggest starting with the milder Volume 1. Then, when you've mastered them (or start to become bored), hop on over to Volume 2 and let the frustration begin!
