Go mining for a jackpot in Crystal Rift, a Cascading Reels slot to be released by Rabcat Gambling. It’s a superb looking 5 reel, 25 payline slot. Central to the action here are the Wild Grids that become active following 3 successive cascade wins. Play this medium variance game on all devices from between 25p and £50 per spin.

First impressions on firing up Crystal Rift are very favourable. The visuals here are terrific. A futuristic looking crystal mine is the setting. On the reels you’ll find 8 different coloured rock symbols. The best of these is the amber rock which pays 2, 10 or 40 times your total stake if you land 3, 4 or 5 on 1 of the game’s 25 paylines. The shimmering white crystal is the wild. This substitutes for all other symbols and pays 40 times your stake if you land 5 in a row.

After every winning spin, you’ll be award a cascade. All of the successful symbols are blasted away and a new set of symbols drops in and replace them. These cascades continue as long as a new winning combination is created. This is known as the Bonus Falls feature.

At the beginning of each spin, a Wild Grid is chosen at random. If you manage to land 3 successive cascade wins in a row, the Wild Grid feature becomes active. All the symbols situated within the Wild Grid turn into wilds for the symbol drop that follows.

There are 4 different levels of Wild Grid – Basic, Super, Mega and Insane. The Basic Wild Grid can contain as few as 2 unlinked positions. If you see an Insane Wild Grid turn active, you could end up with 8 extra wilds in a potentially very lucrative configuration.

There aren’t any traditional bonus features on offer in Crystal Rift. The Cascading Reels game engine and Wild Grids deliver more than enough action to keeps things moving though. As far as volatility goes, we’re in the medium range here with maximum wins of 1,000 times your stake if you manage to fill the reels with wilds and amber rocks.

There’s a futuristic look and sound to Crystal Rift. It’s the kind of thing that could appear in a sci-fi movie. The gameplay is very straightforward and it works well together though. If you enjoy Cascading Reels slots, then the Wild Grid element makes Crystal Rift well worth considering. However, the win potential isn’t as high as I like to would rather play NetEnt’s Gonzo’s Quest or Yggdrasil Gaming’s Gem Rocks.
