Sudoku is a puzzle that has taken the world by storm and since its sudden increase in popularity there have been all manner of variants on the theme. Most these variations have been designed to add an extra level of difficulty to the puzzle, and this is something that can also be said of 3Doku. The traditional puzzle involves working with a two dimensional grid measuring 9 by 9 cells – in 3Doku, an extra dimension is added and you have a 9 by 9 by 9 cube to work with.

Some puzzles may take much longer to complete than others and require you to think several moves ahead, but if you are willing to persevere, you should always win through. If you have been solving puzzles for a while, you may well have found that you can breeze your way through them pretty quickly. If you’re looking for more of a challenge, 3Doku could just be the game for you.

A puzzle comprises 27 individual Sudoku boards; 9 in the X plane, 9 in the Y plane and 9 in the Z plane. This means that any cell you select is actually part of three different boards so making a mistake with one number could have a far great knock on effect. If you start to find that things are just too tricky, you have the option of enabling hints so you will be warned if you enter an incorrect number in a particular cell.
