Gemtastic

Go mining for jackpots of up to 10,000 times your stake in Gemtastic, a jewel-themed slot from Red Tiger Gaming. Played on a 6 reel, 5 row grid, chain reaction wins can send multipliers rocketing by up to 15x. Play this highly volatile game on all devices from between 20p and £10 per spin.

The set up in Gemtastic is very straightforward. The reels are set against a diamond mine backdrop – there you’ll find 9 brightly coloured gemstone symbols. The best of these is the orange stone which awards 1.5. 3, 6 or 12 times your stake if you land 3, 4, 5 or 6 on a payline. Most of these gems are single symbols.

More rewarding still is the rainbow W which is the wild. This substitutes for all other symbols. Land 6 of these in combination and you can look forward to a bumper award of 75 times your total stake.

Gemtastic comes with a chain reaction game engine. After a winning combination hits, the successful symbols are blasted away and new ones drop in from above and replace them. The reactions keep on coming as long as a new winner hits.

More importantly, a multiplier increases by 1 with each successive chain reaction win. Get on a roll here and you could see your payouts boosted by multipliers that can top a massive 15x. This is known as the Lava Multiplier feature.

There’s also the Magic Glow feature – on any spin, a gem may sparkle. If part of a win, they will disperse and transform into wilds on the respin. You could also see 2×2 and 3×3 symbols though in the Mega Gems feature – this helps you win bigger. The Mega Gems can come into play in the Magic Glow feature for Mega Wilds which can quickly get the coins flowing.

The design and gameplay in Gemtastic are simple. This game can still pack a decent payout punch thanks to the multipliers. This is a very volatile game. Expect some lengthy winless spells. When the multipliers reach double figures, some top action is possible – up to 10,000 times your stake on every spin!

This probably won’t be a slot for lovers of classic fruit machines. It owes as much to social media games as classic one-armed bandits. If you fancy a game that delivers straightforward, high variance action, then that’s just what you’ll find here.
