At the start of each puzzle the tiles are arranged in a descending order. To solve the puzzle you must move the tiles such that they are ordered from low to high instead. Tiles can be moved by swapping pairs of adjacent tiles, but tiles can only be swapped when their sum is a multiple of 3 or 5.
Press shift together with an arrow key to swap the marked tile with an adjacant tile.
