Gem Crush slot by Netent is an adjacent cluster pays game where you are paid for 5+ similar symbols with the highest category for 30+ in a cluster. Those pay from 80 down to 10x bet and aside from special symbols, the name tells you the theme here - gems and gems only! Netent never went down the cluster pays route until Aloha! Cluster Pays slot was made many moons ago, and we had a few since including The Legend of Shangri-La Cluster Pays and Aloha! Christmas slot. You get Wild symbols anywhere here, winning symbols are removed in tumbles but the main modifiers are through the special symbols.

Free Games
So you earn 10 free spins for triggering the bonus. You now see better enhancements, namely at least one colossal 2x2 Wild every spin guaranteed, so a win every spin will happen. The transformation rainbows are permanent now, so if one of the 4 coloured low-value symbols is upgraded to the higher one of its colour it stays that way on the reels until the end. You get a 1x increasing multiplier for every 2 spins not including winning tumbles, and an X-strike can randomly occur which adds another 1x to this when it lands. No retriggers or extra spins can occur.
