Based on the innovative cascading reels structure, Gemtastic is a new video slot from Red Tiger Gaming that shows some huge potential. It uses a 6×5 reel set and has 30 fixed paylines where lucky players can hit winnings of up to 10,000 times their original bet.

Red Tiger’s Gemtastic slot is a beautifully designed gem-themed game that takes players deep underground and helps them mine precious gems and treasures. The slot, which was released in January 2019, comes with intense graphics, a great soundtrack, and amazing gameplay that makes it engaging and exciting for players. Some of the symbols appear on 4 or 9 tiles, while others have a magic glow that transforms them into Wilds. The game has a wide range of multipliers that may bring some really huge winnings.

Symbols and Winning Combinations of Gemtastic Slot

Winning CombinationsBefore looking into the symbols in Gemtastic, we should take a look at its reel structure – the reels are not spinning as usual. Here, they are cascading, which means that symbols simply fall onto them and whenever 3 or more matching symbols land on a payline, they are blasted away and the symbols standing above them fall in their positions. More importantly, new symbols fall on the reels, creating a “re-spin” of the reels.

All symbols in this video slot are gems in different colors, sizes, and shapes – 5 smaller gemstones, as well as 4 larger, high-value gems in pink, red, green and golden yellow. The gold-colored stone is the best paying one and players who land 6 gold gems on any of the paylines will receive a payout worth 240 times their stake.

The most exciting symbol in the game, however, is the multicolored Wild symbol, represented by the letter “W”. When 6 Wilds land on a payline, they bring 1,500 times the stake. Of course, this symbol substitutes for all other symbols in the game. It does not appear in the base game, however. As we have mentioned above, some of the regular gems may randomly land glowing on the reels. When they do, they may bring forward the Wild symbols.

Bonus Features of Gemtastic Slot

Bonus imageSome of the symbols may land on the reels with a beautiful, multicolored glow around them. This is called the Magic Glow and when glowing symbols form a winning combination, they are blasted away, giving way to new, cascading symbols. More importantly, once the glowing combos explode, they disperse randomly onto the reels and transform into Wilds for the respin.

This brings us to the second exciting bonus feature in Gemtastic, the Lava Multiplier. For each consecutive respin, the winnings from the round will be multiplied by up to 15 times. After cascading symbols are blasted away for the second time in a row, the multiplier bar standing on the right-hand side of the reels is lit up. With every consecutive win, it increases by 1 and can reach 15x the bet size.

Another interesting feature is the Mega Gems, which appear randomly during the base game and the respin. These gems are the regular gem symbols of the slot but they can cover 4 or even 9 tiles on the reels. These Mega Gems may increase the winning chances and bring great payouts, especially if they land glowing on the reels and form combos. In fact, all these bonus features can happen simultaneously, increasing the wins to hundreds and even thousands of times the original stake.


Gemtastic is certainly one of the most beautiful gem-themed slots and among the best creations of Red Tiger Gaming. The software provider has over 100 games within its portfolio and Gemtastic is different from all of them. It is very volatile so players can expect long losing steaks – although the volatility here is not as high as in other similar games by different development studios.

In fact, wins are quite regular, even though not very frequent. The best thing is that when you win, you will probably win a lot, even if you play with smaller stakes. This slot has a theoretical RTP of 96.00%, which is rather standard for an online slot.
