About Boomstone

Boomstone is a gem-matching puzzle played across a mine wall. Eight gems appear with colors and purity numbers, and matching colors into a vein lets you blast them. Higher purity creates a larger boom, allowing the score to grow as stronger matches build on one another.

The run moves through eight mine layers, with a supply station after each layer and a Boss anomaly at every ending. Gear choices can add color points, double matching blasts, or strengthen the final shot, while changing gear arrangements make each run require fresh decisions.

How to Play Boomstone

Use a mouse or touchscreen to select and arrange matching-colored gems.

Create a gem vein, then blast it to score points.

Read the preview and adapt when a Boss anomaly blocks a color or removes a blast.

Choose mining gear at the supply station after each layer.

Clear all eight mine layers to win.

Tips & Tricks

1Compare colors and purity numbers before committing to a vein, since purer matches produce bigger blasts.
2Plan around the next Boss anomaly when a color is sealed or a blast may be lost.
3Choose supply gear that supports the color and blasting opportunities visible in your current run.
