When players land two or three of the Hardwell bonus symbols they will be awarded with bonus spins that are complete with reel upgrades, and these bonus symbols will only be available on the first, third and fifth reels. When players land two Hardwell bonuses, they are awarded with ten bonus spins and one-reel upgrade whereas landing three Hardwell bonuses awards twenty bonus spins and two-reel upgrades.
The bonus spins can be reactivated and landing one bonus results in five bonus spins and one-reel upgrade, two bonus symbols awards ten bonus spins and two-reel upgrades and landing three bonus symbols will award twenty bonus spins and two-reel upgrades. There is a maximum of three upgrades that can be awarded during the bonus spins round and all the upgrades remain active until the end of the bonus spins and any additional re-spins have been played out.
Prior to commencing with the bonus spins, players are given the opportunity to choose one of four different upgrades for their reels, they then need to tap on the mystery symbol to reveal the upgrade that they have won, and this will be one of the following:
- Two Way win lines where the reels pay out in both directions, right to left and left to right.
- Win Multiplier where players have a random multiplier added to their winnings in the bonus spins and this multiplier will be x2, x3, x4, x5 or x10.
- Expanding wild symbols where players will see all the wild symbols morph into expanding wilds throughout the bonus spins, however, this does not apply to the wild fruit symbols that have been made into wild due to the upgrade applied to the reels.
- Wild fruit symbols where the player will see a regular fruit randomly selected to turn wild reel three and just reel three during the bonus spins round.
There is also a lock and spin game that is randomly triggered and sees regular symbols become locked into place on the reels and there is also a possibility for the golden disc symbols to lock in place rather than the regular symbols. The reels cease to spin once the player has 8 – 15 golden discs locked in place and these will then reveal one regular symbol that replaces all the golden discs for a guaranteed win.
