Power Sun XXL is a 5-reel, 15-line slot from 3 Oaks Gaming, released in October 2025. The game uses a high-volatility format and a 95% RTP. Its design keeps the sun-themed retro style, with an expanded reel set and fixed jackpot potential built into the bonus structure.
The main feature is the Burning Sun-shaped Collect symbol. When it appears, it gathers the values from visible Coin Bonus symbols. The Hold & Win bonus starts when a Collect symbol lands on the centre reel and Bonus symbols land on the other reels. During the feature, only Collect and Bonus symbols can appear, with reel 2 reserved for Collect symbols that lock in place and absorb values from arriving Bonus symbols. Some Bonus symbols may carry fixed Mini, Minor, Major or Grand jackpots.
Players can also trigger the Bonus Game by filling the Sun Metre with Bonus symbols or through the Lucky Spin mechanic. In select markets outside the UK, a buy bonus option is available for the Bonus Game or Super Bonus. The demo version lets players play for free and practice before playing for real money.
