The original Power Sun launched earlier in 2025 on a compact 3×3 grid. XXL Power Sun by 3 Oaks Gaming is its direct follow-up, expanding the layout to 3×5 with 15 paylines and pushing the max win from 1,000x to 4,288x. The fruit symbols, the fiery aesthetic, and the Collect format are all carried over, but the larger reel set opens the bonus for multiple Collect symbols to stack on reel 2 simultaneously. Where the original was a concentrated single-shot, this slot builds toward accumulation. The demo is the best way to get a grip on how the Collect trigger works before the stakes matter.
The Bonus symbol (a gold coin) can land on reels 1 and 3 only, in any game mode. The Collect symbol (the burning sun) is confined to reel 2 only. Neither pays independently. Bonus symbols only award a prize when a Collect symbol lands on the same spin and gathers them. Jackpot symbols on reels 1 and 3 follow the same rule. The Bonus Game begins when at least one Bonus or Jackpot symbol is present on both reel 1 and reel 3, with a Collect symbol on reel 2 , all on the same spin.
Once triggered, the Bonus Game runs as a 3 re-spin Hold and Win round. Only Bonus, Collect and Jackpot symbols appear during the feature. Each new symbol that lands resets the counter to 3. Collect symbols stick to reel 2 for the duration, and up to five can accumulate across its rows. When re-spins run out, the values gathered by all Collect symbols are added together as the bonus payout.
The Triple 7 acts as the Wild and substitutes for all regular symbols. It appears across all three reels but only during the main game — Wilds are absent from the Bonus Game entirely.
In eligible regions, two buy-in options are available. The standard Bonus Game costs 70x the current bet. A Super Bonus Game option is also available at 200x the current bet, and both are played at the bet level at which they are purchased.
The paytable adjusts with the selected bet. Values below are taken from a £1.00 stake, where the full symbol set pays as follows. Bets run from £0.20 to £100.00.

| Bell | 10.00 |

| Orange / Lemon | 1.00 |
| Cherry | 0.50 |
