Roll up, roll up! Take a trip to a big top like no other in Zombie Circus. This 5 reel, 10 payline slot has been created by Relax Gaming and comes with a cracking bonus round that awards free spins where standard symbols can turn into wilds. Play on all devices from between 10p and £100 per spin.

The design in Zombie Circus is good. With fairground tents and stalls in the background, you’ll see lower value A to 10 symbols spinning around the reels as well as a quartet of zombie-style circus performer. The best of them is the blood-spattered woman who awards 4, 10 or 40 times your total stake if you land 3, 4 or 5 on a payline. There’s also a wild. This replaces all other symbols apart from the scatter and pays 5, 15 or 50 times your total stake.

Zombie Circus comes with a Free Spins feature but it has the potential to be a corker. To trigger it, you’ll need to land 3 or more of the carousel bonus symbol on the same spin. You’ll then proceed to the Zombie Wave feature – choose from the 5 zombies. This will determine how many free spins you’ve been awarded.

Any subsequent Zombie Wave picks will reveal a symbol. This symbol will then be wild for the duration of the free spins. You’ll get 2, 3 or 4 Zombie Wave picks if you trigger the feature with 3, 4 or 5 Bonus symbols. Once the picks are done, you’ll go ahead and play your free spins.

You can re-trigger the Zombie Wave feature during the free spins by landing Bonus symbols on reels 1, 3 and 5 on the same spin. Once again, you’ll get a free spins pick followed by wild symbols.

Zombie Circus is a pretty simple game but it’s one we really like. The colourful visuals are well crafted and the madcap backing track fits the theme perfectly. The bonus features offers plenty of potential too, especially if you manage to trigger the feature with more than the minimum 3 Bonus symbols.

We managed to win over 230 times our stake during the Free Spins feature after the transforming wild symbols fell nicely. If you’re looking for an action-packed slot for Halloween, then you’ll do just fine taking a trip to the Zombie Circus. If you like the theme, NetEnt’s Halloween Jack is recommended.
