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.

Getting Started
Welcome to the explosive world of Boomstone! Your mission is simple: eliminate every enemy unit before they can destroy your precious central stone. The game features a vibrant grid where you strategically place bombs to clear paths and defend your territory. At the start, you'll find a limited set of bomb types, each with unique blast radii and damage profiles. Use your mouse to pick up a bomb, then click any empty grid square to deploy it instantly. The game runs smoothly on any device with a touch screen or mouse, making it perfect for quick sessions on the go. As you clear waves of enemies, you unlock new bomb varieties that offer greater range or piercing capabilities, allowing you to tackle tougher opponents. Keep an eye on your remaining bombs; if they run out before the wave ends, the enemies will turn their attention to the stone, and the round ends in defeat.Pro Tips
Timing is everything in Boomstone. The most effective strategy is to clear the outer edges of the grid first, funneling enemies toward the center where your stone sits. This forces them into predictable movement patterns, making your subsequent bomb placements far more accurate. Always reserve at least two bombs for the final wave; you can't afford to be caught off guard. When facing large groups of enemies, prioritize bombs with wider blast radii even if they deal slightly less damage per hit, since clearing the screen quickly reduces the time enemies have to damage the stone. If you're struggling with a specific enemy type, try combining small, frequent bursts rather than one massive explosion; this often breaks their formation more efficiently. Don't forget that the grid wraps around the edges, so a bomb placed near the border can hit enemies circling from the opposite side.Controls
Boomstone uses intuitive mouse-touch controls designed for seamless gameplay. To interact with the game, simply move your mouse cursor over the grid; hovering highlights valid placement spots. Click the left mouse button to pick up the currently selected bomb, and click any empty square to deploy it immediately. There is no cooldown or drag mechanic—every click places the bomb instantly, rewarding quick reflexes and precise aiming. If you have multiple bombs equipped, clicking once selects the next in the queue, allowing rapid-fire sequences without pausing. The interface also supports touch devices perfectly; a single tap functions exactly like a mouse click, making the game fully accessible on tablets and smartphones.
