About the game
Gem Blast is a casual puzzle game where you mine gems across an infinite hex board. You play as a cute robot stranded on an alien planet, searching for ship parts to fix your broken vessel. Using markers and logic, you locate gems while avoiding bombs, then spend your earnings to upgrade the Dig Bot and unlock achievements. It was developed by Avalon Studios.
