If you think you've seen it all when it comes to Sudoku then think again. 3Doku quite literally gives the traditional Sudoku format a third dimension.
3Doku creates a 9x9x9 cube with a staggering 27 Sudoku grids intersecting each other along the three axises. The trick is to solve the 9x9 grid by keeping in mind that you're playing a third sudoku grid at the same time. And if this isn't hard enough, you can increase the difficulty level four times!
The presentation of 3Doku is fine but the obvious drawback is the level of difficulty. This is definitely not a game for those new to Sudoku but superb for those who want the ultimate challenge. One other problem is that the game isn't very well documented although for seasoned Sudoku players, they should be able to work it out.
3Doku is about as tough as Sudoku can get but if you really think you're good, this game will test you to your limits.
