Click on the green flag, and then click on the tiles so that they move towards the free space. Thus, you need to arrange the tiles in the correct order from 1 to 15. The top left corner is considered the beginning. However, in this version you may encounter an unsolvable situation 15-14, namely when at the end two tiles are opposite and there is NO way to line them up correctly. To do this, tile 15 has the super power to jump over tile 14 at the very end, which will lead to victory.
