Whatever, I thought, until I - perhaps mistakenly, or perhaps luckily - clicked on a link from Penny Arcade to a game, still in beta, called Zen of Sudoku.
Dammit. Now I'm hooked.
The basics are simple. You have 9 numbers. Each number can be used once per row and once per column. As well, they are only used once per 3 by 3 square. The board is made up of 9 three by three squares, and your goal is to fill in the rest of the numbers left.
The game itself is simple, too. Calm, Asian style music plays. The opening menu is done in an Asian theme as well, with unlockable items on it (I just unlocked a sailboat, myself). You select the game (or options, or community if you want), select your difficulty, and play.
The game features a tutorial that can teach anyone how to play it. The controls are fairly simple - you simply hold down on a mouse button on an empty square and a list of numbers comes up. You select one and move your mouse off the list. You get a chime if it's correct, and it blinks red and a "bong" if you're not. You can even make "pencil marks", marking multiple possible values to help your memory if you want.
When you finish, the board dissolves into butterflies and you're asked if you want another game. If you've done well, you may have opened up an unlockable feature.
That's it. It's a simple, relaxing, engaging game. There aren't complications when none are needed. If you're looking for a PC version of the game, there's no need to go any further.
