I’m in total shock over how completely UFO has ruined the Sudoku experience. I thought the interface for the GBA and PSP sudoku games were bad, but this game takes it to a whole new level. Your grid is confined to the top screen. This means no touching the grid – navigation is solely through the D-pad, or though the enormous cursor icons on the lower screen. Entering numbers is accomplished by tapping the number or using the L & R buttons and selecting the number. Why L & R? Because the numbers are laid out in a single horizontal row on the bottom. Nope, no purely logical numerical keypad for you! In fact there is no real purpose to the touch abilities at all in this game. Oh, before I forget, the ability to use subscript and superscript to leave yourself notes and hints has been removed from this game. Why? Probably because they didn’t know how to make that work for their new edgy icons that replace 1-9 on their cheesy graphic skins. I can go on and on, but trust me, words cannot convey how awful this interface is. A total waste of my $20 + tax.
