Solar Nova Slot RTP, Details & Wager Limits

Reels/Paylines: 9×9 grid + Cluster Pays

Stakes Range: 10p to £50 per spin

RTP: 96%

Max Win: 10,000 x stake per spin

The Solar Nova slot is played on a 9×9 grid and uses a Cluster Pays mechanic. Winning combinations are created by landing 6 or more matching symbols, adjacent to one another horizontally and/or vertically. The bigger the cluster, the bigger the payout naturally.

Play away from 10p to £50 per spin. Click on the ‘Coins’ icon below the grid to change your stake accordingly using the plus and minus buttons. In countries apart from the UK, you will find an Autoplay facility (‘A’ button) as a Quickspin Mode (via the ‘Settings’ button).

The Solar Nova RTP is 96% which is exactly the same as the 96% online slots average. 56% of that is reserved for the base game and 40% for the free spins. Even if you buy the bonus features (not for UK players I’m afraid), the RTP rate stays to same.

High variance, the maximum win is 10,000 x your total stake per spin. The bigger payouts will derive from the free spins (find out more below).

Theme – fire up your rockets and head to outer space

Theme: Space

High Value Symbol: White Gemstone

Compatibility: Mobile, Tablet, Desktop


With an outer space theme, the Solar Nova slot is quite simply designed. With floating spaceships in the background, the first thing you’ll notice is the epic Star Trek style soundtrack. Looks wise, the colours remind me a little of NetEnt’s Starburst and Starburst XXXtreme.

Symbols on the 9×9 grid include 7 different coloured gemstones. The white gemstone is the most lucrative symbol giving you 80 x your total stake if you land 25 or more in a cluster. The lowest value symbol will pay 10 x stake for 25 or more in comparison.

There is a solar wild symbol that substitutes for all symbols mentioned above. The wild can lead to the Solar Flare feature being triggered randomly in the base game and other extras during the free spins. Solar Nova also benefits from a rocket wild symbol. Also replacing all standard symbols, it comes with a multiplier that increases when part of a win.

Solar Nova Mobile


Produced by Iron Dog Studio using the latest HTML5 technology, Solar Nova has been optimised to be played on all devices. This includes mobiles, tablets, PCs and laptops that use iOS, Windows and Android technology. The large 9×9 grid is better suited to larger devices in my experience.

Solar Nova Bonus Features

The Solar Nova slot comes with 5 bonus features. With tumbles and transforming symbols, Rocked Wilds come with multipliers that can combine if various ones appear at the same time. With teleporting symbols, it focuses on the Free Spins feature where there’s an additional feature that can give you 3×3 Solar Wilds.

Tumble feature

When you get a winning combination, the Tumble feature applies. The winning symbols are destroyed and the remaining symbols tumble down to replace them. The vacant spaces are filled with new symbols tumbling in from above. Allowing for successive wins, the tumbles keep on coming as long as you land a winning cluster/combination.

Solar Flare feature

During the base game, the Solar Wild symbol can randomly trigger the Solar Flare feature on any losing spin. The Solar Wild transforms between 1 and 4 horizontal/vertical spokes into the same symbol. During the free spins, this feature can happen even on winning spins.

Rocket Wild feature

The Rocket Wild substitutes for all normal symbols. If the Rocket is part of a cluster win, the winning symbol will randomly move to an adjacent, vacant position before the tumble occurs. Known as the Rocket Wild feature, all Rockets not part of a win in the base game will be held in place.

Every Rocket contains a multiplier that increases by 1 per tumble if contributing to a win. Furthermore, when the rocket is part of a winning cluster, the value of the Rocket multiplies the win. The multiplier has no limits either. If you get a win with multiple rockets, the associated multipliers are multiplied. For example, a 2x, 3x and 6x multiplier would result in a 36x multiplier.

Symbol Teleportation feature

The Symbol Teleportation feature is triggered randomly on any base game or free spin. The Rocket Wild symbol switches place with a normal gemstone symbol on the board to guarantee a winning combination.

Free Spins feature


If 3 or more Rockets land simultaneously during a base game spin, the Free Spins feature will be activated. With the Rockets locked in place, you will receive 6 free spins. Additional free spins cannot be won unfortunately.

Once in, Rocket Wilds move to a random position on each free spin. Each time it’s part of a win, the multiplier increases by 1. Up to 4 Rocket Wilds can appear at any 1 time.

If a Solar Wild is directly involved in a cluster win, the counter increases by 1. If the Solar Wild is part of 8 winning tumbles, the Solar Nova feature is triggered.

A Solar Nova event expands to Solar Wild into a 3×3 wild for 1 tumble. The Solar Wild then returns to its default size after that tumble.

Finally, there’s a Buy Free Spins feature. Not available in the UK, you have 3 options:

90 x stake Free spins with 3 Rockets + 1x starting multiplier
250 x stake Free spins with 4 Rockets + 1x starting multiplier
300 x stake Free spins with 3 Rockets + 5x starting multiplier

Bonus Features

RTP (96%)

Max Win (10,000 x)


The Solar Nova slot is a good grid game which a few enticing bonus features. Visually like NetEnt’s Starburst, the Rocket Wild feature can lead to various multipliers which multiply by each other for big wins.

The best of the extras is the Free Spins feature which will take approximately 200 spins to activate. With the average payout in the free spins being 80 x stake, Rocker Wild multipliers are present for multipliers. The added wrinkle is the Solar Nova feature where the Solar Wild will appear 3×3 in size for 1 spin/tumble.

With little extras like Push Gaming’s Jammin’ Jars, this grid slot is a good one from Iron Dog Studio that can payout up to 10,000 x your total stake per spin or free spin.

If you like grid slots, I would also recommend Relax Gaming’s Cluster Tumble (20,000 x stake max wins) and Big Time Gaming’s Star Clusters Megaclusters (23,960 x stake payouts) which are my 2 favourites.

  • 10,000 x stake max wins per spin
  • Cluster Pays mechanic
  • Combining Rocket Wild multipliers
  • High variance
