Boomstone

Boomstone is a captivating gem-matching puzzle featuring a roguelike twist. Match gems. Detonate them. See your score skyrocket. Eight luminous gems appear on the mine wall, each assigned a color and a purity value. Align matching colors to form a gem vein and BLAST — the higher the purity, the larger the explosion, causing your score to surge from mere dozens to tens of thousands. Excavate through 8 mine layers, with each one deeper and more abundant. Following every layer, visit the supply station to acquire mining equipment: boost points for a specific color, double the impact of same-color blasts, or amplify your final strike. Since the gear reshuffles every run, no two sessions are identical. Each layer concludes with a Boss anomaly that demands new strategies — hard rock blocks a color, while gas consumes one of your blasts. Study the preview, adjust your approach, and push forward. Complete all 8 layers to emerge victorious! Play instantly without downloading. Learn in 3 seconds, expect ~20 min per run. Use mouse or touch controls on desktop & mobile.
