Gemtastic Casino Slot Features

Magic Glow

The Magic Glow feature may activate on any standard spin. The gems will sparkle and if they form part of a winline they will turn into wilds on the respin. Your Mega Gems can also get the Magic Glow when they form part of a winline. If so, they will break away into separate symbols.

Chain Reaction

When you land a winning combination all of the symbols in that winline break away and new ones will fall into position. These reactions will continue as long as you keep landing winning combinations. With each reaction the multiplier increases by 1x. Get on a good run and you could get the Lava Multiplier, which is 15x.

Mega Gems Feature

This is a stacked symbol. The stacked symbols range from 2x2 to 3x3 giving you higher value winning combinations.
