How to Play Gemtastic

Gemtastic is played on a six reel slot with five rows and 30 fixed paylines. There is the possibility to change the stake by clicking on your current stake, which opens a list of possible stakes to choose from. The minimum bet is £/€ 0.20 per spin, but if you feel lucky you can bet up to a maximum of £/€ 10 per spin.

This Slot also offers automatic spins, by clicking on "AUTO" you can choose up to 100 automatic spins. There are a few more options that can be included, such as "Loss Limit", "Stop on win above" and "Stop on Bonus feature". However, Red Tiger Gaming only lets players play on "AUTO" if they also enter a loss limit.

Gemtastic has 9 standard symbols and 1 special symbol (Wild) that randomly appear during gambling. You can also speed up the spins anytime by clicking on the "TURBO" button.


Mysterious mines deep down, inside the earth, and sparkling stones shining in a mystical blue light await you when playing Gemtastic. Modern graphics and vibrant colors alongside some background music to set the scene complete this game. So gear up, it is mining time!

Special Features - Bonuses & Wilds

Gemtastic offers several features to make this gem-themed slot interesting.


A Symbol that substitutes for all paying symbols. In case of Gemtastic it is triggered by the Magic Glow feature.

Magic Glow

On any spin, a particular gem type may sparkle with a multi-colored Magic Glow. If these gems form part of a winning combo, they will disperse and transform into Wilds on random positions on the respin (all gems from the winning combo disperse and make room for new gems). The Magic Glow may also apply to Mega Gems which, when part of a winning combo, disperse into several smaller Wilds for the respin.

Lava Multiplier

Each win during a spin is multiplied by the number indicated on the Lava Multiplier. Starting with a multiplier of 0 on every new spin, consecutive wins force the multiplier to go up to a maximum of 15x. So with each consecutive win, the multiplier climbs higher up the ladder. This feature is the key to hit big wins and makes it possible to land wins of up to 10,000x your bet.

Mega Gems

Mega Gems are gems of any type having a size of 2x2 or 3x3 to help you land wins more easily.
