The Wild Chase Bonus Round
Once you have managed to land 3 of the Safe Bonus symbols on the reels the main bonus round is triggered, the player is granted an initial 10 Free Spins, and during the bonus round the same slot mechanics are in place with the win re-spins in place, but additional to this you also have Guaranteed Wilds that are added to the reels on each and every spin during the bonus round.
These Multiplier Wilds will only take effect if they form part of a winning combination during that spin, so ideally Guaranteed Wilds near the front reels will be the most optimal.
Definitely an online slot to take for a spin if you are a fan of Jackhammer 1 or 2, or even just a fan of the many previous Quickspin slot releases.
If you are very quick there are some great promotions running for this slot too at InstaCasino where you can bag up to 200 RealSpins (Free Spins No Wagering).
