Summary: Ugly interface!!! Can't use the pen and write the numbers, have to pick from a list of numbers. Very annoying... Very bad when comparing to the interface from Brain Age!!! I would return this game, but Amazon doesn't accept it if game is opened. If you think that this game has a good interface... you haven't tried Brain Age yet!!!!
Summary: It's a fun game with a few different sudoku puzzle options (classic, 8x8, 4x4, etc). I don't like how you have to input/erase/change the numbers into the boxes....expected it to be like the sudoku puzzles on the Brain Age games, but it's not even close.
Summary: While I haven't used all the options, there is a good selection of the classic sudukos. A nice feature is the ability to "pencil" in any number(s) across rows or columns and within a 9x9 without having to think beforehand all the numbers that might be applied to a given cell before you enter. And when you enter more than one number, it appears in a given cell in the sequence from low to high (i.e.1-9), rather than in the order in which it was entered.
Summary: If you already like sudoku puzzles, you will enjoy this game. If you don't like sudoku, then why are you buying this? The game menu is easy to navigate and the controls make sense. This game is just straight puzzling, no weird RPG story built around it or feeble attempts at storylines, just the puzzles. I also really like that it tells you how many of each number are on the board already/how many there are left--it speeds things along nicely.
