Set off explosions on square-shaped gems in Crystal Craash. The peculiarity of this puzzle is that all the crystals are numbered. To earn points, you need to click on groups of three or more crystals with the same digital values. You click on one of the stones selected in the group of crystals. In this case, all the crystals are combined and a pebble with double the value appears at the place where you pressed. As soon as there are no required combinations on the field, the Crystal Craash game will end.
