Solar Nova

Solar Nova from Iron Dog Studio is a 9x9 slot built around cluster-pay mechanics rather than fixed paylines. Wins are formed by matching groups of symbols, while tumbling reels remove winning symbols and bring in new ones for possible chain reactions. The game is set in space and uses a high-volatility model, with RTP versions listed at 96% and 94%.

The feature set includes a constant Solar Wild in the centre of the grid, random Solar Flares that convert cross lines into matching gemstone symbols, and Rocket sticky wilds that remain in place across spins. Each Rocket win increases its multiplier, while three or more Rockets trigger free spins. During bonus play, the Solar Wild can expand into a 3x3 wild area after contributing to eight wins.

A demo version is available to play for free and practice before playing for real money. Bet limits run from £0.10 to £50.00, and the game carries a maximum multiplier of 10,000x. Solar Nova is certified by the UK Gambling Commission.
