Boomstone

Boomstone turns gem-matching into a dig. Eight gems sit on the mine wall at any moment, each one a color and a purity number, and lining several of the same color into a connected vein sets off a blast. A vein of pure, matching stones detonates far bigger than a mixed one, so the game rewards patience over grabbing the first match you see.

Clearing a layer sends you to a supply station between digs, where you pick gear that shapes the run - extra points on one color, doubled blasts, or a single supercharged shot saved for later. The gear resets each run, so no layer plays quite the same way twice, and every eighth layer ends in a boss that forces a different approach.

How to play

Match gems of the same color into a connected vein and tap or click to blast it - the purer the vein, the bigger the score. Between mine layers, visit the supply station and pick gear that boosts a color, doubles same-color blasts, or saves a supercharged shot for later. Watch for the boss at the end of each set of layers; it changes the rules and needs a different plan.

Controls

Mouse or touch only - click or tap gems to connect a vein, then confirm the blast.
