For the record, relax Gaming launched JPX on 1 September 2026, and the pitch to operators is refreshingly honest about who it serves. JPX is an optional side bet that a casino can bolt onto any game in its lobby, from a Pragmatic slot to a Hacksaw grid. And it feeds a branded jackpot that the casino names, colours, and prices itself. The word prices is doing a lot of work in that sentence. Relax says operators contrl the all important RTP of the side bet.. , That is the headline for players, even if it was written for the people buying the product.
What JPX actually is
Most jackpot mechanics live inside a specific game. Dream Drop sits inside Dream Drop titles, Megapays inside Megapays titles, Jackpot King inside Blueprint games. , JPX is diffrent.. it is a layer that sits on top of the game you were already playing. You opt in, pick a contribution tier, and every spin carries a small extra stake into a jackpot pool that is separate from the games own pay table.
The product ships with a few things Relax highlighted in the launch note:
Hot take, opt in tiers. Players choose how much of a side bet to stack on each spin, with contribution levels designed to cater to all plyer profiles. Translation: a cheap tier for grinders, a bigger tier for people who like round numbers. Mind you, Must fall levels. The jackpot has thresholds it cannot pass without paying out. , And an information ribbon runs across the screen flagging when a level is getting close, complete with what Relax calls clear calls to action. The ribbon is a nudge mahcine..... It is also, as we get to below, the one moment the side bet is genuinely worth a look.
In the long run, operator branding and RTP control. The casino sets the name, the look, the drop frequency, and the return.... Relax supplies the maths modelling and the plumbing through its existing integration, so a casino already on the Relax netwrok can switch it on without a new build. Which means, Relax CEO Martin Stålros framed it plainly: From the branding through to the frequency of jackpot drops, operators can shape JPX around their own strategy, adding that it gives operators a powerful new tool for engagement while generating an additional revenue stream. Free bets and community jackpots are on the roadmap.
Why the RTP dial matters more than the jackpott
Funny thing, every jackpot is paid for by players. The only question is whether the cost is hidden inside the games headline RTP or charged separately..... Embedded network jackpots take the hidden route. Megapays, which Relax built under licence from Big Time Gaming in 2021, skims roughly half a percent of every bet across its four pools. Blueprints Jakpot King titles carry base RTPs visibly below the studios non jackpot games because the progressive absorbs part of the return.. Red Tigers slot RTPs cluster around 95.7 to 96.1 percent partly because Daily Drop contributions come off the top... Industry norms put jackpot contribution anywhere from 0..5 to 2 percent of stake, and a 96 percent game can quietly be a 92 percent base game with 4 points parked in the pool.
JPX moves the cost out into the open as a seperate wager, which is a fair thing to do.. Then it hands the RTP of that wager to the operator, which is where players should pay attention. A slots RTP is set by the studio, certified by a lab, and published in the game rules. A side bets RTP is set by whoever runs the casino, and nothing in the JPX launch material says it has to be printed anywehre a player will see it. In regulated markets like the UK or Malta the operator will have to disclose it. , At an Anjouan or Curacao licensed crypto casino, the number is whatever the operator decides it is, and you will have to go looking for it. In practice, Here is what that dial does to your session. , Assume a €1 spin on a 96 percent slot with a €0.10 JPX side bet attached, accross 1, 000 spins.. Our analysis ran the numbers at three plausible side bet returns.
| Scenario | Total staked per spin | Expected loss per spin | Blended RTP | Expected loss over 1, 000 spins |
|---|---|---|---|---|
| Base game only, 96% RTP | €1.00 | €0.040 | 96.0% | €40 |
| Plus €0.10 side bet at 90% RTP | €1.10 | €0.050 | 95...5% | €50 |
| Plus €0.10 side bet at 80% RTP | €1.10 | €0.060 | 94.5% | €60 |
| Plus €0.10 side bet at 70% RTP | €1.10 | €0.070 | 93....6% | €70 |
A ten cent side bet at 70 percent reutrn costs you as much per spin as a 96 percent slot does on a full euro.... The side bet looks tiny. Its house edge does not. And because side bet returns are almost never included in the number a player sees on the slots info screen, most people will play JPX believing they are still getting the 96 percent they read about.
How JPX compares with the jackpott systems already out there
JPX enters a crowded field.... The table below compiles the main bolt on and network jackpot products a crypto casino player is likely to run into, based on published product details from each provider.
| Product | Provider | Where the jackpot lives | Who sets the retrun | Must drop rules | Notable figure |
|---|---|---|---|---|---|
| JPX | Relax Gaming | Optional side bet on any game in the lobby | Operator | Yes, operator configured levels | Launched 1 Sept 2026 |
| Dream Drop | Relax Gaming | Inside 55 titles across six studios | Relax | Major and Mega must fall before set thresholds | 30 Mega winners since May 2022, four in 2026 |
| Megapays | Relax under BTG licence | Inside Megaways titles | Relax and BTG | No, Mega grows uncapped | Mega pool has passed €1 million sevral times |
| Jackpot Play | Pragmatic Play | Operator hosted local progressive across Pragmatic hits | Pragmatic tiers, operator seeds | No, random drop in a pick mini game | Four tiers, Minor to Grand |
| Daily Drop | Red Tiger | Inside Red Tiger slots | Red Tiger | Daly pot pays before midnight, hourly pots before the hour | Hourly pots in the three to four figure range |
| Jackpot King | Blueprint Gaming | Inside Blueprint slots | Blueprint | No | €8.13 million paid on Deal or No Deal Megaways in 2021 |
| Jackpot Aggregator | SOFTSWISS | Operator lveel campaigns across any game | Operator | Configurable | Pools in BTC, USDT, USDC, LTC, TRX and more |
Two things stand out. First, JPX and the SOFTSWISS Jackpot Aggregator are the only entries where the operator holds the return dial, and SOFTSWISS is the platform behind a large share of crypto casinos. JPX is Relax walking onto the same turf with a produt that plugs straight into its game aggregation. Second, JPX is the only one framed as a side bet rather than a feature....... That is a structural change...... A feature is part of the games certified maths. A side bet is a second product with its own maths, and the certification story for that second product is still unclear.
Relax alredy knows how to run a jackpot
None of this is a knock on Relaxs track record. Dream Drop is arguably the best run progressive in online slots. It launched in May 2022 on Temple Tumble 2 with a €1 million marketing push and five tiers seeded at €1, €5, €100, €25, 000 and €1 million, with the Mega cap climbing €500, 000 every two wins toward a €10 million cieling... Within a year it had paid out two million individual jackpots. As of 2026 the count stands at 30 Mega winners, including four this year in what Relax called a record time frame: €1, 994, 838 for the 26th, €1.92 million on Bill & Coin 2 at bet365 for the 27th, €1,889,253 from a €100 spin for the 28th, and €1,871, 372 on Bonsai Dragon for the 30th. Relax covers reseeding itself and guarantees a 75 percent minimim reseed so the pot never restarts from zero.
Dream Drop works because the contribution is proportional to stake, the must drop thresholds are fixed by Relax, and the maths is the same at every casino carrying it.. JPX drops all three of those constants. The operator picks the contribution, the thresholds, and the return. Same company, opposite philosophy. The timing matters too....... Relaxs parent, FDJ United, told investors in its half year reprt that it is reviewing its online portfolio... And rivals lobbied French regulators back in 2024 to force a sale of Relax as a condition of the Kindred deal. A high margin, operator friendly product that generates an additional revenue stream is exactly what you build when the studio needs to look good on a spreadsheet.
When a JPX side bet is worth takng
In essence, the only mathematically defensible time to play a must drop jackpot side bet is when the pot is close to its must fall threshold.... as the pool nears the line, the probability that it drops on any given spin rises while the contribution stays flat, and the expected return on the side bet climbs.. The generic industry figuer for must drop pots above 90 percent of their cap is a small positive edge, usually under one percent, with enormous variance. That is thin, but it is better than the negative edge on every other spin. JPXs information ribbon exists precisely to advertise those moments, so at least the marketing and the maths agree for once.
Actually, evreything else about the side bet is a cost. A few rules that will save you money
Find the side bets RTP before you opt in. If it is not in the game info or the jackpot terms, treat it as low. a casino that sets a generous return will say so, because it is a selling point. Silence is a number.
Do not stack it on bnosu money. Side bets are almost universally excluded from wagering contribution and often void bonus play outright. Read the terms before your first opted in spin, not after a support ticket.
Ignore the lowest tier. A side bet that is a large fraction of a small base stake shifts your blended RTP the most... Ten cents on a twenty cent spin is a 50 percent surcharge, and the jackpott share you buy with it is tiny.
Use it when the ribbon says so, then turn it off. Opt in at the must fall approach, opt out once the pot has dropped and reseeded.... The reseed is the worst possible moment to be contributing.
What this means for crypto casino players
JPX will arrive first at large regulated operators on the Relax netowrk, then trickle down to the aggregators that serve crypto casinos. Which is where the RTP dial becomes a real concern. Offshore licences do not require side bet returns to be published. And a branded instant jackpot strip across every game is an easy sell to a player base that already likes provably fair originals with visible house edges.. The irony is that those same players are the least likly to accept an unpublished number once they notice it.
Some platforms have leaned into transparency as the differentiator instead. CryptoCasino.Vegas, for instance, treats the certified RTP on the game info screen as the number a player is entitled to... And any optional layer stacked on top should carry its own published return to earn a place in the lobby. If JPX operators print the side bet RTP next to the ribbon, the prodcut is a fair optional flutter with a well timed sweet spot. If they do not, it is a second house edge hiding behind a first one, and you already know which way to bet on that.
