Rules and Gameplay

Solar Nova, developed by Iron Dog Studio, is a cosmic adventure set in a vast outer space environment on a 9×9 grid using the Cluster Pays mechanic. Players aim to create winning combinations by landing clusters of 6 or more matching symbols, either vertically or horizontally. The game supports bets ranging from $0.10 to $50 per spin, making it accessible for casual players and high rollers alike. Its medium-high volatility and an RTP of 96% offer a balanced mix of risk and reward, with the potential for payouts up to 10,000x the stake. Note that RTP can vary, dropping to as low as 94% or 88% depending on the casino.

Bonus Features

Solar Nova is packed with engaging bonus features that enhance the gaming experience:

  • Solar Flare: Randomly transforms 1 to 4 central rows/columns into the same gem symbol, potentially on any spin.
  • Rocket Wilds: These special wilds move to adjacent positions with each win, increasing their multiplier by +1 after each tumble, with no upper limit.
  • Symbol Teleportation: Randomly swaps a Rocket Wild with a regular symbol, increasing win potential.
  • Free Spins: Triggered by landing 3 Rocket Wilds, awarding 6 Free Spins with Rocket Wilds carrying over their multipliers.
  • Buy Bonus Feature: Allows players to directly purchase Free Spins, with options for different setups of Rocket Wilds and multipliers.


The symbols in Solar Nova are a vibrant collection of cosmic gems and special wilds:

  • Gems: Seven different colored gemstones represent the standard pay symbols, with payouts for clusters of 25+ symbols ranging from 10x to 80x the stake.
  • Solar Wild: A fixed wild symbol at the center of the grid, substituting for any regular symbols to form winning combinations.
  • Rocket Wilds: Substitute for any normal symbols and come with an increasing multiplier feature for successive wins.


The game’s payouts are driven by the cluster pays mechanism, with significant winning potential:

Symbol Min Cluster Size (6+) Max Payout (25+ symbols)
White Gemstone 6 80x
Other Gemstones 6 10x to 80x
Rocket Wilds N/A Multiplier increases with each win

Note: The maximum win value is capped at 10,000x the bet, providing ample opportunity for substantial payouts.


As Solar Nova uses the Cluster Pays system instead of traditional paylines, wins are awarded based on clusters of 6 or more matching symbols, either horizontally or vertically adjacent. This innovative system allows for a dynamic gameplay experience, where the size and composition of clusters directly influence the payout.
