Boomstone
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.
Prioritize forming high-purity veins by matching gems of the same color early in a layer to maximize explosion damage. Use the supply station gear strategically—save double blasts for tough anomalies or when you need to clear a blocked color. Always check the Boss anomaly preview before each layer to plan your moves, especially when a color is sealed or gas threatens your progress.
Boomstone features eight mine layers, each progressively deeper and more valuable, where players match eight glowing gems by color to form gem veins. Each gem has a purity value, and the higher the purity of a matched color, the bigger the explosion and score boost. After completing a layer, players visit a supply station to acquire randomized mining gear, such as bonus points for a color, double damage on same-color blasts, or a supercharged final shot. Each layer ends with a unique Boss anomaly—like sealed colors or gas that consumes blasts—that requires players to adapt strategies based on the preview. The game combines puzzle mechanics with roguelike progression, offering a fresh experience with each run due to randomized gear and evolving challenges.
