Use the free spaces to move your tiles to get unique elements in the same row and column. Check the numbers on each tile carefully. You then move them using the same mechanism as in a sliding puzzle game. If a tile appears more than once, it will turn red. This will allow you to spot them quickly at a glance. Expect complex puzzles to solve as you progress. Have fun!
Play this game with the mouse.
