How Gem Rocks works
The game combines cascading wins, cluster symbols and win-all-ways.
How wins are paid
Consecutive wins add a cluster of up to 4x4 symbols to the reels, and the cluster comes with a guaranteed win.
What to look for in the demo
Count the cascades in a row. The bigger clusters arrive only after several wins in one spin.
