Jokerizer is a high-volatility slot by Yggdrasil Gaming on a 5-reel, 3-row grid with 10 paylines, first released on March 1, 2016. Its signature is the Jokerizer mode - a post-win state where jokers unlock mystery wins of up to 6000 coins. The published figures around the game are unusually inconsistent: the only RTP we could verify on a live operator page is 94.22%, while maximum-win listings range from x500.00 through £12,000 and 12,000x up to the provider's €60,000. This review explains the mechanic and sorts out which numbers you can actually rely on.
Jokerizer at a glance
The verified core: Yggdrasil Gaming, 5 reels and 3 rows, 10 paylines, high volatility, a published hit frequency figure of 9.9, mystery wins up to 6000 coins in the Jokerizer mode, and a minimum stake listed from £0.01. Beyond that core, the published figures split by source - the table keeps them separate on purpose rather than pretending there is one answer.

The Jokerizer mode explained
The Jokerizer mode is the whole game: after a win, you can carry on spinning in a special state where the win you just banked is at stake and joker symbols become the target. Jokers landing in this mode unlock mystery wins that reach up to 6000 coins - that figure is published by the provider and is the headline prize of the mechanic. The choice the game puts in front of you every time - bank the win or risk it in Jokerizer mode for a shot at the mystery payout - is what gives a simple 10-line slot its high volatility rating. There are no free spins and no progressive jackpot; this one risk-and-reward loop carries everything.
Jokerizer RTP: the number nobody agrees on
The provider itself publishes Jokerizer's RTP as a range - 88.8% to 98% - because the game's return depends on how you use the optional Jokerizer mode. Review sites advertise the top of that range: 98.00% is the figure you will meet in their titles. Meanwhile, the figure we verified on a live UK operator page is 94.22%. All three numbers are real, and that is exactly the problem: the advertised 98.00% assumes the most favourable play of the risk mode, while the operator build you meet may be set lower. The in-game information screen is the only source that tells you the RTP of the exact build in front of you - check it before you form any expectation from headline numbers.
Theme and design
The provider pitches Jokerizer as a circus act - a carnival-atmosphere take on the joker slot with the character as ringmaster - and by its published description the visuals and audio carry that staging. Judged from the provider's own materials rather than first-hand play, the presentation sits closer to a theatrical show than to the plain fruit-machine look of most classic jokers; mechanically, though, it remains a compact 10-line game that reads instantly.
Stakes and the maximum win: four different answers
The published maximum win depends on where you look: the provider lists €60,000, one aggregator lists 12,000x, one operator page lists £12,000, and another listing shows x500.00. These are not typos - they reflect different builds, markets and eras of the same game, and it is exactly why we label every figure on this page with its source type. Stakes start from a listed £0.01 minimum, with one operator capping bets at 20 per spin. The practical advice is the same as with the RTP: the paytable and limits of the build in your lobby are the real ones.
Where to play the Jokerizer demo
The provider's own site offers the game for free play, and that is the authoritative demo. In Great Britain, free-to-play demos require age verification before you can spin - a UKGC regulatory requirement, and the reason we link to demos rather than embedding them. Demo availability can also vary by jurisdiction.
Where Jokerizer sits among joker slots
Jokerizer is the risk-choice entry in the joker family: where Joker Pro chases one respin outcome and Mystery Joker 6000 runs its own mystery-win ladder, Jokerizer asks you to re-stake what you just won. Players who want published, consistent mathematics will be happier elsewhere in the family; players who enjoy a deliberate gamble decision every few spins get the purest version of that idea here.
What we like
- A genuinely distinctive mechanic: the post-win Jokerizer mode with mystery wins up to 6000 coins
- Compact, readable 5x3 game with 10 paylines - nothing hidden in the rules
- Low entry point with a listed £0.01 minimum stake
- Official free play available on the provider's site
What to keep in mind
- Published figures disagree across sources - max win is listed four different ways
- The only RTP we could verify (94.22%) is well below the figures advertised in search results
- High volatility with no free spins round to break up dry stretches
Our verdict
By the criteria we publish - transparency of the provider's figures, availability of an official demo, clarity of the mechanics and how fairly the game communicates its rules - Jokerizer lands in the middle. The mechanic is excellent and explained cleanly in-game, and the demo is freely available; but the published numbers around the game are the least consistent we have documented in this family, and the build you will actually meet in a UK lobby carries a lower verified RTP than the advertising suggests. Play it for the Jokerizer mode, not for the headline figures. As with every game we review for Great Britain: play only at UKGC-licensed operators, the legal age is 18+, and if play stops being fun, help and self-exclusion tools are available - gamble responsibly.
