Crystal Cave Match 3

Down in the cave, colour is all you have. Blocks of one shade go into a series of three or more, that scores, and the scoring is the only thing holding up a gauge that starts falling the moment the level opens.

Nothing accumulates between runs. No boosters to earn, no levels banked, no progress to protect — which strips the format down to a single question asked over and over: can you find the next series before the gauge notices you stopped. Sessions therefore end cleanly rather than fizzling, and starting again costs a click.

Crystals against dark rock is a good pairing for this kind of speed: saturated pieces on a black background separate instantly, so the board never becomes the reason you lost.

1. Swap two adjacent blocks to form a series of three or more crystals of one colour.
2. Watch the gauge — it falls continuously and ends the run when empty.
3. Clear steadily rather than searching for a long series.
4. Restart immediately; nothing carries over anyway.

Work within one quadrant of the board at a time. The gauge punishes travel more than it punishes small clears, and a series found two squares away always beats a better one across the cave.
