To adjust their stake, players only need to choose the appropriate coin denomination, which ranges from $0.01 to $2. Depending on this, the wager itself will be anywhere from a mere $0.25 to $50 per spin.

The game looks stunning. Players are lured into a dark and mysterious cavern where the reels are located containing differently coloured rock symbols. The one you'll want to see on the reels more often is the amber rock, which can pay up to 40x the wager for 5 across a payline. A shimmering white crystal is the game's Wild, and as usual, it can substitute for all other icons, awarding a hefty payout worth 40x your wager for 5 of a kind.

Players get a cascade after a winning spin, which means all icons that formed the win get removed from the reels, while a new set of symbols replaces them. This will continue as long as new winning combinations are formed. This is the Bonus Falls feature.

Before a spin, a Wild Grid is chosen, and if a player succeeds in landing three cascade wins in a row, they will unlock the Wild Grid feature. This feature has four different levels – Basic, Super, Mega and Insane. The latter awards 8 extra Wilds, resulting in very lucrative combinations.

Unfortunately, Crystal Rift doesn't offer any traditional bonus rounds, although the Cascading Reels game engine and Wild Grids will deliver enough action, while the maximum win of 1,000x the bet definitely sounds like a good reason to check this title out.

This is a medium variance title, with an average return to player of 96%.
