How to Play

There are only 5 paylines in the Oni Hunter slot, as well as a simple 3x3 layout so it is very easy to navigate and understand. Granted, the features may seem confusing to newbie players, but truth is, it’s not that complicated once you get the hang of it. We will share how the game modes and special symbols work in more detail, below, and for now, let’s see what you need to get started:

  • Find the best casino where you can play Oni Hunter, register there, make a deposit and launch the slot
  • When you are in the game we first recommend placing your bet to get an accurate pay table, according to your stake. The minimum bet in Oni Hunter is €0.50 and the maximum is €100
  • After that press the symbol with 3 lines, located on the left bottom corner, and from there you can access the settings tutorial and pay table. Make sure that you read the tutorial thoroughly and understand how the features work
  • Note that there is also a bonus buy option in Oni Hunter, that allows you to activate free spins immediately
  • If you've purchased free spins the game will automatically start, and if you want to play the game normally just click the spin button in the middle when you're ready to play!

Oni Hunter RTP and Volatility

8.2 
Oni Hunter is a highly volatile slot that has a 96.97% RTP.
The volatility of the Oni Hunter slot is set at a high level, and that means that the risk of losing in a spin will be increased in this game, but it also means that when you get a winning symbol combination it will provide a bigger payoff as well! As for the Return to Player rate, one that shows how much you will be paid back upon the win, in the base game, it is set at 96.97% but with the Buy feature, it will be increased to 97.30%. In both cases, this is a good RTP potential, above average.

Theme

8.4 

Oni Hunter is an Asian-themed slot, with a pretty, anime-inspired design. So those of you that love these types of animation will probably also enjoy the vibe of this game as well. In the background, you will see the lovely forest, the reels are made of bright neon lights and there is oriental music that plays in the background. From an aesthetic point of view, Oni Hunter looks like a fine, average anime-themed game.

Now as for the symbols you have regular ones and specials - Respin, Bonus, Treasure box and Seven symbol. Regular symbols are sushi, paper crane, fish, fan and paper lantern and these are the lowest paying ones in the game, with sushi being the least valuable symbol that pays 0.10x your stake for 3 symbols. The more valuable symbols are the man in purple, the man in green, the lady in orange and the warrior or oni hunter, specifically.

There are special symbols as well. Respin looks like a bird and will activate the Respins feature if you land on one of these symbols on the reels. The Bonus symbol will activate the Pick One Bonus Feature. A Seven symbol will trigger the Combat Free Spins, and finally, the Treasure Free Spins symbol will trigger the Treasure Free Spins feature.

Bonus Rounds & Free Spins

9.2 

Respins

To trigger the Respins feature, you will need to land on the Respin symbols that randomly drop on the reels, and respins reels to help you trigger other features. By collecting 6 Respin symbols you will activate the Combat Free Spins mode.

Free Spins

When you will trigger the Combat Free Spins feature, by collecting 6 Respin symbols or by landing on 1 Seven symbol, you will be given 10 free spins. And if you again land on the Seven symbol it will retrigger the feature, giving you 10 more free spins.

Pick One Bonus

This feature is activated if you land on the Bonus symbol. In Pick One Bonus, you will need to pick a flag that will either award you with cash prizes or a Seven symbol. By selecting the cash price it will be added to your balance, and if you pick the Seven symbol it will trigger the Combat Free Spins feature.

Treasure Free Spins

For that, click on the green shopping card next to the reels and the cost of this feature will be automatically calculated pending on your current bet.

Oni Hunter Demo Play

The demo is the unique version of the slot, that allows you to play Oni Hunter for free. Specifically, in the demo, you will be provided virtual coins that you'll use to place bets, and that is so you could try out all the features of the game and learn how it works before you start playing for real money. And yes, just like with the mobile version the features of the demo remain the same as in the paid version of the slot.

Max Win

6.4 
The top win in Oni Hunter is 100x your total stake.
Considering that Oni Hunter is a high volatility slot, with increased risk, the max win you get of 100x the total stake is a pretty low potential. There is no jackpot option, but what makes it better is that the game does have special features like Respins that help you improve your winning chances.

Overall Rating

8.1
Oni Hunter is a rather interesting game with a bunch of amazing features and a decent anime design that the fans of Asian-themed floods will no doubt enjoy. What is also amazing about this online slot is that while it does have a rather low top win you have a lot of opportunities to get a decent price given the variety of features - from free spins with retrigger option, to Bonus Buy - there is a lot to play with. Still, with so many game modes and high volatility, we would especially recommend Oni Hunter to more experienced players.
