The idea is to rotate the rows/columns of cubes until the number you want shows on the front face of a particular cube and then "touch and hold" to LOCK. Once locked it will not rotate.
If you are not quite sure about locking at any stage, simply "short touch" to highlight a number. You can deselect and unlock in the same way.
The objective of course is to fill each row, column, diagonal and group of 6 sub-sections with each of the numbers 1-6 once.
There are 9 levels increasing with difficulty but each level has 1000's of different games.
Your SCORE will be calculated on completion of each game, determined by the number of clues used, your moves total and time, highest score best.
