Precious and semi-precious stones seem to be solid in appearance, but in fact, the hardness of each is completely different. Many people know that the hardest crystal on a scale from one to ten is diamond. Nine belongs to corundum, eight to topaz, seven to quartz, and so on. In Gem Blast, you don't need this gradation, but you need to know which stone to click on. For the rest to explode. There will be four crystal shapes with five colors on the playing field. When you click on a stone, it will change color and shape to the one that explodes. To complete the level, you must clear the field. However, the number of steps is limited in Gem Blast.
