When 2 Scatter symbols land in view on the reels there are transformed into special respin wilds.
These wilds then move down the reels one step down each spin and this continues until they are removed from the reels or a 3rd scatter symbol lands on the reels and triggers the free spins bonus round.
Heist Bonus Game – Free Spins
Once the bonus round is triggered you are granted an initial 10 free spins, the main aim of the bonus round is to collect as many of the golden keys as possible from the reels as these unlock the special wild symbols once 3 of the same colour have been collected (recorded on the screen during the bonus).
Each time you collect a key you are also granted 1 extra spin, once 3 of the same key are collected the special wild symbol is added to the reels with Walking, Sticky and Climbing Wilds on offer.
To add to the mix, if any of the wilds cross paths they are given a special multiplier to any wins, and if you unlock all 3 features the monkey is released from the cage and the disco party begins!
