Joker Stoker has two RTP figures: 96.07% in Endorphina’s catalogue and 98.07% in the help of the official demo. We don’t know why they differ, so this page shows both, together with the EUR settings we recorded and the questions the available data can’t answer. For what each symbol pays, see the rules guide.
Which RTP is right: 96.07% or 98.07%?
Right now nobody can say. Here is where each figure comes from:
| Where the figure appears | Figure | What it refers to |
|---|---|---|
| Provider catalogue, original game | 96.07% | The RTP the catalogue publishes |
| EUR demo help, English and Russian | 98.07% | The game RTP shown in the inspected client |
| Same help, game including Bonus Pop | 95.05%–95.92% | A separate range, not split by package |
The English help showed 98.07% too, so this isn’t a case of the Russian translation printing a different number. The cause is still unconfirmed. That gives us no reason to call either source wrong, to average the two or to quietly pick the more attractive one.
The Bonus Pop range needs its label as well. The help doesn’t say which package gets the low end and which gets the high end, and neither the number of Free Games nor the package price fills that gap. The Risk Game isn’t part of the main-game RTP at all. It has its own return figures that depend on how you play; see the card-game rules.
What RTP means in practice: it’s the theoretical share of all stakes the game pays back over a very long run. It isn’t a forecast of where your balance will end up. Seeing 98.07% doesn’t tell you how many of your next spins will win, or whether a feature will earn back what you paid for it. Those questions need the full spread of outcomes and the odds of specific events, and a single percentage doesn’t contain them.
Medium-Low is the volatility rating on Endorphina’s catalogue page. It’s the provider’s own category, not a hit frequency we measured. It can’t tell you how long a losing streak might last, when a big win might land or what a short session will look like.
Which game and which settings does this page describe?
This page is about Endorphina’s original Joker Stoker. The provider listing gives five reels, four rows and 40 fixed paylines. The official demo we inspected also includes rules for Wilds, Free Games, Bonus Pop and a Risk Game. None of this automatically applies to Joker Stoker Dice, which the version comparison covers separately.
Each number on this page has a source. The layout comes from the provider catalogue. The €0.40–€140.00 total-stake range comes from the EUR demo help we inspected on 6 November 2026. Putting both on one page doesn’t mean that stake range holds for every currency or every operator.
If you compare settings yourself, note the full title and the source of each number.
How do we know each specification?
The catalogue, the screens and our own calculations each tell you something different:
| Type of evidence | Example on this page | What it proves |
|---|---|---|
| Provider catalogue | 5 × 4 layout and 40 fixed paylines | What the provider publishes for the original game |
| Built-in rules | Stake range and how lines are read | What the help says in that particular client |
| What the screen showed | Selected €0.40 stake and Bonus Pop prices | What was displayed during our inspection |
| Calculation | €20.00 divided by €0.40 gives 50× | A ratio between known inputs, with stated assumptions |
| Open question | Overall maximum win | A value the evidence doesn’t establish |
All of this comes from rules and settings on screen. We didn’t play any rounds or complete any feature purchases.
How do you check whether another game window matches?
A matching title is only the starting point. To see how close another window is to what we recorded, compare these fields together:
| Field | What we recorded | What to check in another window |
|---|---|---|
| Full title | Joker Stoker, original | Whether the title includes Dice |
| Currency and selected total stake | EUR and €0.40 | The units used for prices and wins |
| Help label | ver. 1.1 | The label actually shown, without guessing what it means technically |
| Game RTP | 98.07% in EN and RU help | The number and the heading around it |
| Stake range | €0.40–€140.00 | The limits in that client’s help |
| Bonus Pop | Panel present in the inspected demo | Whether it’s offered, and the full price |
The 1.1 help label isn’t confirmed as a maths model version or a client release date. Two clients with the same label could still use different settings.
If a field doesn’t match, keep both readings with their context. A different currency, for example, should be noted as a different currency. Don’t convert the EUR paytable and present the result as a local paytable you actually saw. And if Bonus Pop is missing, that alone doesn’t prove it’s a different game: the rules already say some operators may leave it out.
Which maths questions are still open?
The material we inspected doesn’t give the overall maximum win, the hit frequency, the chance of triggering Free Games or the odds of any symbol combination. These are four different numbers, and you can’t fill one gap by borrowing a figure you do know.
| Question | Why the known figures aren’t enough | What would answer it |
|---|---|---|
| What’s the most a full round or feature can pay? | One line award only covers that combination | A version-specific overall limit or a full maths specification |
| How often does a spin pay something? | RTP is total return, not a count of wins | A stated hit frequency or the full outcome distribution |
| How often do Free Games start? | The Scatter table lists awards, not how often they happen | Confirmed probabilities for the trigger conditions |
| How likely is a given paytable combination? | A cash payout comes without a frequency | The outcome probabilities or a reel-distribution model |
A game can have a high return and still make a particular event rare, because the return depends on both the size of the awards and how likely they are. The paytable gives you the sizes but not the odds. Counting symbol types or visible positions won’t rebuild those odds from what we have.
The five-Wild example is a 50× line-award calculation, not a maximum for the whole round. We didn’t test any prediction method.
Why isn't 55× the same kind of number as 50×?
Some calculations below divide by the same €0.40 stake, but they measure different things. That’s why the top number of each fraction is always shown:
| Calculation at the inspected €0.40 total stake | Result | What it means |
|---|---|---|
| €20.00 five-Wild line award ÷ €0.40 | 50× | What that line award is worth relative to the total stake |
| €22.00 Bonus Pop entry price ÷ €0.40 | 55× | What the 10-game package costs relative to the total stake |
| €43.60 Bonus Pop entry price ÷ €0.40 | 109× | What the 20-game package costs relative to the total stake |
| €65.60 Bonus Pop entry price ÷ €0.40 | 164× | What the 30-game package costs relative to the total stake |
All four use the same recorded EUR configuration. The first is a win; the other three are what you spend. Writing all of them with ”×” doesn’t turn them into predictions, and it doesn’t make an entry price a win you can expect. The full paytable explains how a winning line turns into cash.
Percentages need the same care. The Risk Game’s 84% is the average return per round if you play without looking at the dealer’s card. It isn’t the chance that one of the four card positions wins. Turning a return figure into a win probability takes a model that the percentage on its own doesn’t give you.
What did our inspection actually cover?
We opened the original game through the official Play Demo route, read the interface and the built-in help, and opened the Bonus Pop price panel. Later, we went through the rules again in English and checked them against the Russian record. For Free Games, that second pass matters: it confirms that you can win more free games during the feature and that the initial stake stays the same.
A separate schedule for those extra awards and any extra Free Games multiplier are still unspecified. The Free Games section quotes the wording and its limits.
We didn’t play any spins, buy any packages or play any Risk Game rounds. So this page covers the rules and settings on screen. It doesn’t cover measured payout frequencies, real session returns or how every feature plays out. It also doesn’t vouch for any operator, for performance on physical phones or for the settings a particular casino uses.
To look at the current interface yourself, use the official demo on this site. If what you see differs from our dated record, note the context and look for the reason behind that specific difference. The inspection date tells you when we recorded these settings. It isn’t the game’s release date.
For when the game came out and what else the studio makes, read the Endorphina provider guide.
Frequently asked questions
What should I keep with an RTP screenshot?
The full game title, where the figure came from, the client currency, the language, the help label and the heading next to the number. A main-game figure, a Bonus Pop range and a Risk Game return describe different things, so they shouldn't be mixed up.
Did switching the demo language explain the RTP difference?
No. Both the English and the Russian help show 98.07%, while the provider catalogue lists 96.07%. The language check rules out a translation slip, but it doesn't tell us the real cause.
Does help version 1.1 tell me the maths configuration?
No. All we know is that the help screen is labelled 1.1. That isn't confirmed as a maths model ID or a release date, and two clients with the same label could still use different settings.
What does Medium-Low volatility actually tell me?
Only the provider's broad rating. It gives no hit frequency, no longest losing streak and no pattern you can expect in a session.
Can one line payout tell me the maximum of a whole feature?
No. The 50× figure is one line of five Wilds measured against the inspected total stake. A maximum for the whole feature would need its own confirmed rule.
Will every casino use these EUR settings?
Not necessarily. These figures come from the official demo screens recorded on 6 November 2026. Check the title, currency, stake range, available features and help in the casino's own game window.
