About Boomstone
Match gems. Blast them. Watch the score explode. Boomstone is an addictive gem-matching puzzle with a roguelike twist. Eight glowing gems appear on the mine wall, each with a color and a purity number. Line up matching colors into a gem vein and BLAST — the purer the vein, the bigger the boom, until your score snowballs from dozens to tens of thousands. Dig through 8 mine layers, each deeper and richer. After every layer, hit the supply station and grab mining gear: add bonus points to a color, double same-color blasts, or supercharge your final shot. Every run reshuffles the gear, so no two runs play the same. Each layer ends in a Boss anomaly that forces fresh tactics — tough rock seals off a color, gas eats one of your blasts. Read the preview, adapt, break through. Clear all 8 layers to win! Instant play, no download. 3 seconds to learn, ~20 min per run. Mouse or touch, desktop & mobile.
Boomstone is a free puzzle game that runs directly in your browser — there is nothing to install and no account to create. It works on desktop, tablet and phone, and you can start playing straight away.
