Well to be honest,its just plain Sudoku.You either hate it,or love it.
The game's presentation really doesn't matter for this kind of game,but I feel the need to address it.While playing your game of Sudoku,the game provides neat backgrounds representing the Greek's elements of fire,water,and so on and so on,you get the point.It doesn't add anything to the game play,but its just there to please the eye when your really thinking.The in-game controls work on the PSP,and it really makes the game easier.The presentation is good and it is sub standard for a Sudoku game.
Final Verdict: Go!Sudoku is a decent game that you can't really bash.For what it does,it provides an endless amount of Sudoku fun that can really make you scratch your head in confusion.
