Gameplay, RTP, and Variance

Jokerizer sits in a unique category of slots because it deploys two unusual features. The first is that its RTP – the average amount players can expect to win from a slot over time – fluctuates by ten percentage points during gameplay. In the world of online slots, there’s a huge difference between Jokerizer’s two RTP inflections: in the base game, this drops way down to 88.8%, before climbing all the way up to 98% during the Jokerizer mode. This fluctuation mimics the experience of riding an exhilarating rollercoaster, which is precisely the effect Yggdrasil is trying to draw out in this game. It also grants Jokerizer a high volatility mark, meaning that players may be waiting a while for successful spins, but when they come, the chances of sustaining them become much higher. Jokerizer’s second striking feature is that it uses the win-both-ways payline structure. This means players can strike wins on the reels from both the conventional left to right, and from right to left – just as you can on NetEnt’s classic slot, Starburst.

Bonus Features

Jokerizer is really a hybrid slot situated between the classic and video genres. Its modern aesthetics and gameplay twists places it firmly in the latter, but the reels are populated by classic slot iconography, including all the most famous fruit symbols. More significantly, this nod to the classics means that Jokerizer is limited in its bonus offering. There are no free spins, bonus rounds, wilds, or multipliers to be claimed here, which is very much an echo of the simpler three-reel slot of old. The only familiar bonus feature in this game is the Joker scatter. These can only appear on the middle three reels; if three of them land, players will instantly be rewarded with a mystery prize – the highest amount to be won here is the game’s max jackpot of 6,000 coins. There is, however, one significant other bonus feature in this game: the Jokerizer mode. Forming any winning combination on the reels triggers the Jokerizer mode and instantly boosts the game’s RTP from 88.8 to 98%. Further wins gained here will boost players’ Jokerizer credit, which is displayed at the top of the reels following a win. During the Jokerizer mode, players will only need to land two Joker scatters to trigger the mystery win, and are able to collect their coins at any time.

Mobile and Tablet Experience

Yggdrasil always looks out for the mobile gambler, and Jokerizer is certainly no different. This game can be played on any Android, iOS and desktop device, and is supported by Chrome, Internet Explorer, Safari and Firefox browser platforms.

Design, Graphics, and Sound

One of the benchmarks of Yggdrasil is that it produces highly visual and aesthetically ambitious slots. Although Jokerizer makes use of some fairly basic slot symbols, they’re all a pleasure to look at and shimmer on the screen. There are six symbols in total: cherries, lemons, grapes, bells, sevens, and the Joker himself. What really brings Jokerizer to life is the carnival atmosphere of the backing soundtrack. This bold and imposing sound design is the perfect accompaniment to the game’s wacky environment. We also love the way the game builds tension after one joker scatter has landed – when this happens, the adjacent middle reels start cascading in anticipation of further jokers. In the background, the carnival is really brought to life by various theme park rides. There’s a merry-go-round, a rollercoaster, and a spooky tunnel – lord only knows what quirky horrors lie within. If Baz Luhrmann were to set a film in a carnival, this is what it would look like!

Questions and answers

Summary

Jokerizer is a truly unique slot. Its win-both-ways payline structure and Jokerizer mode means there’s nothing else like it out there. Once again, Yggdrasil’s impressive attention to detail delivers exceptional sound and visual graphics on this slot, and players will feel immersed in the crazed carnival atmosphere. It must be said, however, that Jokerizer won’t be to everyone’s tastes, and isn’t suitable for all budgets. The minimum stake of £1 is high for an online slot, and the game’s base RTP of 88.8% – combined with its high variance – means that wins will be too few and far between for some players. Regardless of whether varying RTP rates are suitable for players or not, many online gamblers will simply prefer to have a constant in this area so that they can better regulate their budgets.
