Casinos to Play Gemtastic Slot

Do these gems hold untold riches?

With up to 10,000x your bet wins possible they might. This Gemtastic slot machine by Red Tiger is a 6 reel, 30 payline casino game featuring cascading reels with increasing multipliers, random wilds and mega gems.

It’s got all the makings of a great video slot, but how does it actually play and what typical wins can you expect?

Well, that’s what this Gemtastic slot review is here to find out.

Open up the game and you’re greeted with a 6×5 reel layout with a variety of different coloured and sized gems. Why sized? Well that’s cause this game comes with Mega Gems symbols as standard throughout your spins.

So you could end up with a mixture of symbols covering 1×1, 2×2 or 3×3 spaces on screen at once.

This makes for some interesting spins and more chances at creating a winning paylines.

Before we get to the main way in which you’ll get bigger wins in this game lets talk about the wild feature.

Magic Glow feature adds wilds to the reels

On any spin a selection of symbols might appear with a multi-coloured rainbow glow around them.

If they do and form part of a winning payline then they have the potential to transform themselves in to wilds. Not only that but the wild symbols will then spread themselves around the reels in the hope for creating a win.

We say that these symbols have the potential to create more wilds, cause there’s no guarantee they will.

Throughout our testing of this Gemtastic game for this review, we rarely triggered it even though many glowing and sparkling symbols appeared.

But that’s ok cause there’s still one main way to win in Red Tiger casino slot that can help create some huge wins.

Mega Gems, Magic Glow and Multipliers

Cascading Reel wins with Lava Multiplier

So the main feature in this casino game is the cascading reels.

Not sure what cascading reels are? Well, on any spin if you create a winning combination of symbols, these symbols will dissapear and more will drop down from above to replace the empty spaces.

It gives you an opportunity to get more wins without spending any more real money.

Fans of Gonzo’s Quest or Jungle Jim will understand.

Except in this Gemtastic slot, Red Tiger have decided to combine this feature with an increasing multiplier they call the Lava Multiplier.

On each consecutive cascade win the multiplier to the right of screen will increase by at least 1x. This can go all they way up to 15x your overall win on multiple consecutive cascade wins.

A feature that offers the chance for some huge winning combos.

The maximum we have managed to get was around 7x our wins leaving us with around 20x our bet. There’s obviously the chance for more with a top win of 10,000x your bet possible.

But think more like 2x to 3x multiplier with around 3 – 10x your bet wins on average.

Are the Gemtastic online slot riches worth spinning for?

Even though there are a combination of fun features in our experience they didn’t combine well enough to give us any ultimate heart pounding thrills.

The thrills come with the cascading reels and multipliers but when you look at the real wins you get from these they don’t do much to top up your casino balance.

Combine that with it’s high volatility and you’ll be having to budget and wait for any payouts of a decent size.

One redeeming factor for many will be that it has a low 0.10 minimum bet letting you experience what this game has to offer on a smallish budget.

Overall the Gemtastic mobile slot and online game is good but we’d prefer to play on other Red Tiger slots like Dragon’s Fire and Laser Fruit.

Go take it for a spin yourself, who knows these shiny gems may just hold some real cash wins for the lucky few.
