Texas based Lightsphere LLC announces Cryptoku 1.1, a fast-paced number game for the iPhone and iPod touch. Cryptoku is a unique new number puzzle with a computer hacking theme. Players catch the numbers as they fall from the top of the screen, then place them into the grid to solve each level. Like Sudoku, each number can only appear in the grid once. But unlike Sudoku, the numbers and the grid itself can change. It’s a fast-paced game that will challenge players’ logic skills.
