Gemtastic – Introduction
Put on your hard hat and pack your tools—time to head into the mine. This cave has a slightly unsettling vibe, though: leave the game idle and you’ll hear strange sounds and eerie footsteps echoing through the speekers. Yikes. Still, once you hit spin, those unmistakable Red Tiger soundwaves kick in and start to tickle your tympanic membrane. Interestingly, Gemtastic doesn’t use traditional spinning reels at all. Instead, it runs on a cascading game engine across a 6×5 grid with 30 paylines.
Sure, the huge potential is what grabbed our attention first, but Gemtastic offers more than just that. In this Red Tiger Gaming release, players get a solid lineup of features including Lava Multipliers, Magic Glow and Mega Gems. It’s available on practically any device you can name and supports over 30 languages. Vietnamese or Colombian? Go for it. You can jump in with stakes from 0.20 EUR per spin and go up to 10 EUR if you prefer. Red Tiger themselves rate it as a maximum volatile slot, so it’s wise to play with caution.
On the visual side, Gemtastic drops you into a mysterious lava cavern packed with glowing treasures, and as usual for this provider, the presentation comes with top notch graphics and fluid gameplay. Leave it running and you’ll even see the reel set breathe—small detail for some, but a neat extra that helps it feel premium.
Gemtastic – Symbols, Paytable & Features

There’s no shortage of precious crystals to dig up here. On the reels, you’ll see 5 smaller gemstones as the low-value symbols, along with 4 bigger high-value gems in pink, red, green and yellow. Land 6 yellow gems on a payline and you’ll collect 8 times your stake. The rainbow coloured wild is the real standout, paying 50 times your stake for 6 across a payline.
In the base setup, all gems show as 1×1 symbols, but they can also drop in as 2×2 or even 3×3 Mega Gems. Also watch for sparkling gems—if they’re part of a winning combo, they’ll scatter away and then turn into wilds on the following re-spin.
Gemtastic doesn’t come with a standard free spin feature. Instead, the main attraction is the Lava Multiplier. Each time you hit a winning combination, the Lava Multiplier ladder activates, and every consecutive win pushes the multiplier higher, up to a top value of 15x. The upside can be huge, with the possibility of wins reaching 10,000 times your stake.
Gemtastic – Conclusion
If you enjoy slots built around chain reactions, Gemtastic is well worth a try. It’s clean and simple, making it easy for almost anyone to start playing without needing to overthink it.
And as we found out firsthand, it can throw out an absurd number of wilds. Combine that with a tasty multiplier and the payouts can get pretty wild. If there’s one minor downside, it’s the limited paylines, though it’s definitely not a deal-breaker.
