Adjustable RTP games for operators

Most studios sell you one RTP per game and that's it. Your margins, your markets and your bonus policy are all different, so we let you choose the setting per game, including low RTP versions.

Why operators ask for adjustable RTP

An operator working on tight margins doesn't run the same numbers as a crypto casino with heavy cashback, and neither of them runs the same numbers as a sweepstakes or social site. Yet most game providers hand everyone the same RTP. The result is familiar: operators either eat the margin, or they take good games out of the lobby because the maths doesn't fit their business.

Adjustable RTP fixes that. The game, the art and the features stay exactly the same; only the long-term payout setting changes. You pick the setting that matches your model.

How it works with Nocturn Play

• Several RTP settings per game. Each of our games is built and tested in more than one version, from a standard setting down to low RTP versions.
• Chosen per game, by you. You set the version game by game in our back office. One title can run a standard setting while another runs a lower one.
• Same game on screen. Players see the same symbols, features, bonus buy and max win. What changes is how often the game pays over millions of rounds, not what it looks like.
• Every version is tested. Each setting goes through millions of simulated rounds on the server, and recorded test rounds are replayed before release. We describe the method in how we test slot maths.
• Outcomes decided on our server. The browser only displays the result, so the setting can't be changed or read on the player's side.

Which games

Adjustable settings are available on our games, for example line slots like Black Vigil and Mist Dragon, ways slots like Gridiron Noir and Viking Raid, cluster slots like Lunar Alchemy and Black Jaguar Temple, and non-slot games such as Ghost Fleet and Fox Festival. See them all, and play them free, on the games page.

Low RTP slots: who they are for

Low RTP versions make sense for operators who give a lot back in another form: large welcome bonuses, cashback, rakeback, free spins on every deposit, or a loyalty programme that pays out heavily. They also suit platforms whose costs on GGR leave little room. We don't push one setting over another; we tell you honestly what each one does to the player experience, and you decide.

How to get the settings

The settings we can open and the games they apply to depend on your markets and how you integrate, so we agree them with each partner. Partners who integrate us directly get the full list of settings when we start working together. Read more on our page for aggregators looking for a new game provider and on the partners page.
