Step Sudoku Lite app for iPhone and iPad

Step Sudoku is a new and fun variant on the normal Sudoku puzzle that will keep you entertained for hours.

Step Sudoku introduces nine color groups that are created in a disjointed fashion to make a more challenging puzzle. This replaces the normal 3x3 blocks in the Sudoku grid.

How to play:
Place a number from 1-9 in each empty tile so that each row and each column and each group of colored tiles contain all the numbers from 1-9.

Features:
* New color groups.
* All puzzels are solvable with logic.
* The advance generator produces single * solution puzzle only.
* Hints mode to show incorrectly placed numbers.
* Supports notes.
* Supports undo.
* Supports auto note population. (Disables the timer.)
* 5000 pre-created layouts and solutions and a real time mask generation creates a large number of possible games.
