The PopWins feature adds extra rows and extra paylines to the existing reel set. To trigger the feature, you need to collect pops. You collect pops with every winning combination you create. The winnings symbols then pop and you get 2 of them instead of 1 on each reel. In the best-case scenario, you end up with 7 symbols per reel and 33, 614 ways to win.
Collect 7 pops to trigger the multiplier bonus. Every time you collect 7 pops, the multiplier increases 1x.
You gain access to the bonus mode when you get a fully expanded reel set of 7 symbols on each reel. In this case, you are given a random wild and a 2x multiplier.
This is an unusual Yggdrasil offering, and frankly, we have mixed feelings about it. On one hand, it is different from the standard slot games. On the other hand, it does not offer anything groundbreaking or even captivating.
The Por Rocks slot is expected to go live sometime in March 2020. As we are carrying out this review a few weeks ahead of the launch date, some in-game elements might be missing or incomplete. We will update this review once the slot hits all Yggdrasil casinos.
