Tetroku is a game for the iPhone and the iPod. It’s a pulse racing puzzle adventure of strategy based on Sudoku and Tetris.

You will have to position the blocks as they fall so that the numbers do not appear in the same row, column or box. The strategic placement of ‘wild’ (?), ‘random’ blocks and the formation of the ‘slice bonus’ will help you complete the grid of 81 squares.

Sudoku X is another variant of the original Sudoku.

The rules of Sudoku X are simple, just enter the numbers 1 – 9 once in each row, column and 3 x 3 square within the Sudoku X puzzle grid.
