About Kluster Krystals Megaclusters

Here at 21.co.uk we’re no strangers to fantastic gem-themed slots. Take the Starburst slot is an examples of that. However, Relax Gaming’s Kluster Krystals Megaclusters offers something to our online UK casino that both of those games don’t - the Megaclusters engine.

If you’re unfamiliar with Megaclusters, this means that when players land wins on the reels, an upgrade symbol will appear next to the cluster with the potential to provide double, treble or even quadruple wins. This style of game also has high volatility and an above-average RTP. Of course, this is above average for online slots in the UK, and if you’re looking for a higher Return To Player, you should check out our live casino games, which have a substantially higher RTP. However, if bonus features are your forte, then you’ll definitely want to stay with Kluster Krystals Megaclusters, which has six brilliant features for you to play through. These are split into three main features and three miniature features; however, the miniature features have enough about them to offer big wins.

Kluster Krystals Megaclusters Bonus Features:

Symbol Upgrades and Multipliers

Landing winning clusters will allow players to utilise the Symbol Upgrade feature. Upgrades will come in four forms, ranging from singles to quadruples. These symbols can be upgraded. When multipliers land on the reels, they will appear with up to 10x as their base multiplier. These multipliers can be upgraded up to four times and will be increased by the base value. This means that if you begin with an x5 multiplier, you may end up with an x20 multiplier.

Free Spins

Upgrade a bonus symbol to its maximum value and you will be provided with seven Free Spins. This is the standard Free Spins bonus that can be found in most casino games. However, this slot allows you to activate any of the bonus features, including the three miniature features which are:

Krystal Vanish - If activated, this bonus allows players to select one gem to be completely removed from the reels.

Krystal Boost - If activated, this will upgrade all visible symbols on the reels by the base multiplier.

Krystal Kut - Removes all visible normal symbols from the reels.
