How do free spins start in 3 Wonders Zoo?

Each scattered magic ticket scatter can open a zoo gate. Each ticket opens one of three gates, activating 1, 2, or all 3 wild features. It’s a 3 Wonders series title from Yggdrasil’s Masters program, made by Boomerang, so check out more Yggdrasil slots as well. The base game flows along smoothly, and the real fun begins the moment magic tickets land.

What are the three wild features?

The first is a wild multiplier of up to 8x, and the second is sticky wilds that stay on the reels throughout free spins. The third is the wild row, where an entire horizontal row becomes wild. The more gates open, the more the wilds layer up. Because the three features are so different in nature, the character of the free spins changes a lot depending on which gates open. You could say it’s a nice mix of multiplier, fixed, and expanding types.

What happens when all three gates open?

The wild multiplier, sticky wilds, and wild row all work at once. Wilds stack across the reels, which can make for a scene where wins grow substantially. As the official description puts it, it’s the moment the 3 Wonders free spins turn truly wild. When a wild row overlaps the spots where sticky wilds have stacked and multipliers are added too, you can even expect a screen mostly filled with wilds.

What are the hit frequency and volatility like?

The published hit frequency is a high 34.03%, and volatility is medium-high. The max win of 1,524x is on the modest side, which makes it easy to enjoy for a long time without pressure. Bonus buy is also supported. The bet range is wide, from €0.25 to €150, so it’s also good for trying different amounts in the demo. Another approach is to use bonus buy to trigger free spins several times and compare the gate combinations that open.

What should I check first in the demo?

The base RTP is 96.00%, with 94% and 90.5% versions also available. Volatility is medium-high, and the max win is 1,524x. In the demo, watch which gates open when a few magic tickets gather, and how the free spins results change depending on the number of gates. Thanks to the high hit frequency, you can test it for quite a long time even with demo credits.
