Peter & Sons slots

Who makes Peter & Sons slots?

Peter & Sons is a game development studio founded in 2019. It describes itself as international rather than tied to one country, and its website’s copyright is held by Spinart Ltd. Alongside slots it makes scratch cards and crash games, and by its own count its games are offered by more than 1,000 operators.

According to a studio profile on a trade site, the business had more than 40 games, released a new one each month and counted Barbarossa among its most popular. In 2026 the studio collected four awards at the MiGEA ceremony. The family-business name is branding; we haven’t confirmed who founded it, so we don’t name anyone.

The same profile reported that SkillOnNet invested in Peter & Sons in 2023. SkillOnNet is also the group name of Skill On Net Limited, the company that runs PlayOJO, one of the casinos whose offers appear on this site. We mention it so you can weigh our coverage; it doesn’t tell you which Peter & Sons games PlayOJO lists. Our advertiser disclosure explains how the site is funded.

How Peter & Sons slots reach UK casinos

A young studio has a practical problem: every casino uses different software, and connecting to each one takes time and money. This studio solved much of that by working through larger suppliers’ partner programmes, which let a smaller developer build on the bigger company’s technology and reach its casino customers. It is the same distribution layer described in our explainer on what a slot aggregator is.

In July 2022 InterGame reported Wild One as the latest Peter & Sons title released through YG Masters, following Water Blox Gigablox and Xibalba. Gigablox is Yggdrasil’s own mechanic for oversized symbols, which shows how partner programmes can give a small studio access to a bigger company’s features. See our pages on Yggdrasil and Relax Gaming for the partners.

1. The studio designs the game and its maths model.
2. The game is built on the partner’s technology and tested by an approved test house for each regulated market.
3. The partner offers the game to casinos connected to its platform.
4. Each casino decides whether to list it, and which approved RTP version to run.
5. You find it in the lobby, sometimes filed under the partner’s name rather than Peter & Sons.

Peter & Sons games you may see

These are the titles named in the sources we checked. We don’t have verified specifications for them, so the table shows what is confirmed and what to check yourself.

With a release every month, the catalogue moves quickly, so newer games may be more prominent in lobbies than these. Our new slots guide covers how releases reach casinos, and how new slots are released explains the timings.

Slots, scratch cards and crash games compared

The studio makes three kinds of instant-result game, and they are regulated slightly differently in Great Britain. Slots must take at least 2.5 seconds per game cycle and can’t offer autoplay, under rules in force since 31 October 2021. Since 17 January 2025 similar design rules extend to other online casino games, with a minimum of 5 seconds per game cycle for non-slot games.

Whatever the format, the result is fixed by the random number generator and the animation only reveals it. The game cycle page explains why speed rules focus on the time between results.

Peter & Sons RTP and what play costs

Because we haven’t confirmed RTPs for individual Peter & Sons games, the most useful thing we can do is show how to read the figure when you find it. Open the help screen, find the theoretical return, and work out the long-run cost. At 50p a spin, 100 spins is £50 staked:

• at a 96% RTP the long-run average cost is £2;
• at 95% it is £2.50;
• at 94% it is £3.

Those are averages over a vast number of spins; one session can lose much more, or return more. Our RTP explainer and RTP variants pages explain why the same game can show different figures at different casinos.

Are Peter & Sons slots licensed in the UK?

The studio profile lists the UK among Peter & Sons’ licences, along with Malta, Sweden, Denmark, Greece and Ontario. We haven’t matched a Gambling Commission account number to the studio, so we don’t quote one; the Commission’s business register (opens in a new tab) lets you search for it. When a game is supplied through a partner programme, the partner’s own licence and testing also play a part.

Before release in Britain, games must be checked by an approved test house. The Commission’s guidance on test houses (opens in a new tab) describes their role, and our how machines are tested page explains what is examined.

UK stake limits and game rules for Peter & Sons slots

British versions of Peter & Sons slots follow the same rules as every online slot: a stake ceiling of £5 a spin for anyone 25 or older and £2 for 18 to 24 year olds, set out in the Commission’s stake limit guidance (opens in a new tab); no autoplay; at least 2.5 seconds per spin; no turbo or slam-stop; and no celebrating a return equal to or below the stake. Bonus buys aren’t offered at UK-licensed casinos. Our slot game design rules page has the details.

To turn a max win into pounds, multiply the cap in the help screen by your stake: a 5,000x cap at the £2 limit would be £10,000. That is only an illustration; check the actual cap.

Myths about small slot studios

• “Smaller studios pay more to attract players.” Returns are set by each game’s maths and version, not by the studio’s size.
• “A game listed under the distributor is a copy.” Partner-programme games are original studio titles released on the partner’s platform.
• “Crash games can be timed.” The crash point is decided by the RNG at the start; cashing out early only chooses when you stop, not what the round would have done.
• “New releases pay more in their first weeks.” A game’s maths doesn’t change with its age; see are new slots better than old ones?

Where to play Peter & Sons slots

Game availability varies and changes, and we can’t confirm which Peter & Sons titles our partner casinos list, so search each lobby by game name. None of these is a Peter & Sons promotion: they are welcome deals for new players aged 18+, with terms applying.

Coral offers 100 free spins, each worth 10p on selected games, when you deposit and bet £10 or more on slots; accept within 48 hours, use within 7 days, no wagering on the winnings. Ladbrokes, after a deposit and £10 of slot play, credits 50 free spins on each of the first 10 days (500 in all, 10p each, no wagering). PlayOJO, whose operator’s group invested in Peter & Sons as noted above, offers 80 free spins at 10p on Big Bass Bonanza for a first deposit of at least £10, with winnings paid in cash. Some e-wallets and prepaid cards don’t qualify, and Coral and Ladbrokes share an operator. More on our casinos page.
