Boomstone

Begin with jewels. Crush them. Watch the chain reaction explode. Boomstone is an addictive roguelike jewel-matching puzzle where eight glowing gems appear on the mine wall, each carrying a color and purity value. Match colors in the gem bed and uncover deeper mines as you dig through eight layered stages, each one richer than the last. After every layer, visit the supply station to upgrade your run with tools that add points to a color, duplicate an explosion of the same color, or strengthen your last shot. Every race changes the team, making each run unique. Beat the boss anomaly at the end of each level and clear all eight layers to win. Instant play, no downloads, mouse or touch.
