An eruption of coins is the goal in Gem Rocks, a 6 reel, 4,096 ways to win video slot from Yggdrasil Gaming. Available on desktop, tablet and mobile devices, the game is played using a cascading reels game engine where symbol drops follow each successive win. Get on a roll and you can land giant 4×4 Gem Rock clusters complete with guaranteed wins. Stakes range from between 25p and £50 per spin.
As usual for an Yggdrasil Gaming game, there’s little to grumble about as far as design is concerned. Set against a rocky backdrop, the reels include 8 brightly coloured gemstone symbols. Most rewarding is the red star – land 3, 4, 5 or 6 of these in combination and you’ll pocket 15, 30, 50 or 75 coins. That doesn’t sound like much. The win all ways game engine can multiply those numbers if you land a decent cluster of matching symbols.
After a successful spin, you’ll trigger the Dropdown Wins feature – the winning symbols catch light and removed from play. New symbols drop down to replace them and a new payout consideration is made. These continue as long as a new winner lands.
Get on a roll here and land successive wins and you’ll benefit from expanded Gem Rock symbols. After 2 successive wins, you’ll get a 2×2 Gem Rock made up of identical matching symbols. The Gem Rock Expands to 3×3 after 5 straight wins. Land a 9-symbol drop wins in a row and you’ll earn a giant 4×4 Gem Rock. Every time a Gem Rock appears you’re guaranteed to land a winning combination. This is called the Gem Rocks feature.
All of the action in Gem Rocks centres on the base game – there aren’t any free spins to speak of. The cascading reels deliver a steady stream of action so you shouldn’t read too much into the lack of free spins. The giant Gem Rock clusters add a new dimension and make a nice change of pace from the standard expanding multiplier you often find in symbol drop video slots.
As usual with Yggdrasil Gaming, the visuals here are very well crafted. The gameplay is a little unusual for a game from this developer but it works very well though. Get on a roll with the symbol drops and land a big Gem Rock and the earth could move if your luck is in. If you like cascading wins, Play ‘N Go’s Viking Runecraft is a superb choice.
