This is a fully loaded, ad-free version of Spheroku™.

The rules of Spheroku are the same as in Sudoku: 9 columns, 9 rows and 9 distinct areas must contain the same 9 elements without repeating any of them. When you start, most of those elements are missing and you must find out where do they fit.

Basically, Spheroku would be just another Sudoku App in a very crowded field... However, there is a new twist, that takes it apart from all other Sudoku Apps: because its grid is wrapped on a sphere, Spheroku is not static, but must be rotated, observed and even memorized. There is also another difference -- instead of 9 numbers, Spheroku uses 9 colors which makes the game experience even more challenging and fun. Altogether, working on Spheroku is reminiscent of solving the Rubik's cube. Sudoku & Rubik's Cube - two of most popular brain twisters in history combined in one... Not a bad combination!

Be not intimidated though, we have no doubt you will solve your first Spheroku in no time. We did a lot of testing to make sure that the Beginner puzzles can be solved by everyone. As you learn, you will be able to move to more difficult settings and feel your brain getting bigger, healthier and sharper!

Spheroku App is packed with features that makes it very flexible... Players have the ability to switch between 4 different modes while continuing the same game -in 2d or 3d, using colors or numbers. Additional options include keeping time, score as well as allowing, or disallowing the player to make mistakes, or use cheats.

This paid version of Spheroku is packed with 400 puzzles divided into 4 difficulty setting containing 100 puzzles each. Just to play one time each game would take months, so it is well worth it's purchase price.
