Hypno-Hippo is a 5 reel, 25 payline slot from Novomatic that can be played 50p to £50 per spin across desktop, mobile and tablet devices. It features lots of exotic animals and is all about the HYPNO feature where you can get up to 16 free spins and the hippo casts spells on the 3 middle reels where certain symbols substitute for others.

Graphically, Hypno-Hippo has cartoon style graphics and features plenty of exotic animals including monkeys, elephants, hyenas and chickens. There’s also regular playing cards (A, K, Q, J and 10) and grass. The most valuable symbol is the elephant giving you 200 times your stake for 5 across a payline.

1 thing to note – you can form wins when getting just 1 elephant and 2 of the monkey. The wild HYPNO symbol is the wild symbol and substitutes for all symbols except the playing cards oddly.

The chicken is the scatter symbol with doesn’t trigger any bonus feature – 5 on a payline will give you 50 times your stake. What you want is 3 HYPNO wilds to trigger the HYPNO feature which is a free spins game – you will get 8 free spins initially.

The hippo then casts his spell on the 3 middle reels (reels 2, 3 and 4) – the elephant, monkey and hyena symbols then replace for chicken symbols but acts as chickens. This increases your winning potential as more chickens appear on the reels more frequently. You can also retrigger the feature giving you a total of 16 free spins.

Hypno-Hippo is an odd slot albeit colourful and fun – the free spins feature is also a little strange but has the potential to pay out quite nicely as there’s plenty of chicken scatters on the reels. This medium variance game has the potential to pay up to 500 times your stake on each free spin so it’s definitely worthwhile. If you like animal themed slots, IGT’s Get Clucky is recommended.
