About This Game

Boomstone is a gem-matching puzzle with a bold roguelike twist that makes every blast feel earned. Eight glowing gems sit in a vein on the mine wall, each carrying a color and a purity number. Line up matching colors into a connected vein and set it off; the purer the line, the bigger the explosion, and clever chains push your score from double digits into the tens of thousands. The dig runs eight mine layers deep, each richer than the last, and after every layer you stop at a supply station to grab mining gear, such as bonus points for one color, doubled same-color blasts, or other powerful upgrades that shape your next run. It plays instantly in the browser on phones and desktops alike.

How to Play

Play with a mouse on desktop or with touch on a phone; both feel identical. Select a gem and drag or tap along matching colors to draw a connected vein across the mine wall, then release to blast the whole line at once. The purity numbers on each gem decide the payout, so stretch veins through the purest stones you can reach before detonating. Watch how falling gems refill the wall, because one blast often sets up the next. After finishing a mine layer, visit the supply station and choose gear that suits your plan, like extra points for a color or doubled same-color blasts. Clear all eight layers and keep the score snowball rolling.
