It is time to harvest the gems. In the game Gem Blocks Collapse, we found rich deposits for you and offer you to pick up shining gems for free. But there are certain rules for collecting. The task is to remove all elements from the field. Click on groups of identical stones. It is desirable that there should be at least two, otherwise you will lose points by two hundred for a single gem. If you immediately remove seven or more items, you will receive a reward: a magnet, a bomb or an arrow. They can be used for more effective cleaning of the field.
