Animal slots can be cute, predatory or just plain odd, and the numbers here range wider than in almost any other theme. The lowest RTP in the theme belongs to Games Global’s Mega Moolah at 88.12%, because it is a progressive jackpot slot from 2006 and a share of every stake feeds the prize pool. The highest is Kalamba Games’ Blazing Bull at 97.42%. Close behind is Quickspin’s Big Bad Wolf at 97.34%, though its ceiling is only x1225, whereas the Megaways edition, at 96.05% RTP, promises x30,540 and very high volatility.
Pragmatic Play fields the largest group. The Dog House is high volatility with x6750, the Megaways version caps at x12,305, and the comparison of The Dog House and its Megaways sequel spells out how they play differently. The buffalo of Buffalo King sit at medium volatility and advertise x93,750. Great Rhino Megaways and Mustang Gold are low volatility, and Big Bass Bonanza returns 96.71% with a x2100 cap.
Push Gaming has built an entire universe out of animals. Razor Shark from 2019 lists x50,000, its follow-up Razor Returns x100,000, Big Bamboo 2 reaches x75,000 and Bison Battle and Fire Hopper hold x50,000 each. All are high volatility, which makes them heavy going on a thin bankroll. ELK Studios works differently: Pirots, Pirots 2, 3 and 4 all show 94.0% RTP and x10,000, while Nitropolis tops out at x50,000.
The quietest rides are NetEnt’s Butterfly Staxx (low volatility, 96.8% RTP, x300) and Yggdrasil’s Penguin City (low, x1647). PG Soft supplies the Fortune family: Fortune Tiger at x2500, Fortune Ox at x2000 and Fortune Rabbit at x5000, all medium.
Then come the oddballs: Thunderkick’s Pink Elephants 2 (high, x10,000), BGaming’s Elvis Frog TRUEWAYS, Red Tiger’s Cocks and Robbers (medium, x11,454) and Hacksaw Gaming’s Beam Boys, about kittens and laser pointers.
To pick: steady players will like Butterfly Staxx and Fortune Ox, while those waiting for rare big hits will enjoy Razor Returns and Big Bad Wolf Megaways. How games like Mega Moolah actually work is covered in our jackpot slots guide.
