Descend into a cavern walled with colored gems across a 7x7 grid. Mining the gems is your work: every cluster of 5 or more matching gems pays, clears from the grid, and fills a progress meter that awards 8 free spins when full. Crystalium is a medium-high volatility, cluster-pays slot from SwinttGames. Cloning wilds expand in straight lines or cross patterns to complete extra clusters, and inside the free spins the meter becomes an infinite progress bar adding spins and multipliers after wins. Repeated cascades and steadily rising multipliers in that round can build to about 5,548x your stake. Here is how you play.

Watch for clusters of 5 or more matching symbols to clear the grid.
Each win fills the progress meter, which can trigger 8 free spins.
