Peter & Sons casino games

Who is behind Peter & Sons casino games?

The studio is young, founded in 2019, that describes itself as an international game development company. The copyright line on its website names Spinart Ltd, and trade coverage lists Yann Bautista as founder and commercial director. The studio makes three kinds of product: video slots, online scratchcards and crash games. By its own count, its games are live with more than 1,000 operators worldwide.

Trade listings put the catalogue somewhere above 40 titles, which is small next to the established groups on our providers hub. What earns the studio attention is its look. Coverage repeatedly describes hand-drawn artwork, strong sound design and eccentric themes. In 2026 it collected four awards at the MiGEA ceremony, an industry event held in Malta.

Best-known Peter & Sons slots

Our verified slot database holds no RTP, volatility or max win figures for Peter & Sons, so the table names the games trade coverage mentions and leaves the maths to each game’s help screen. That is deliberate: we would rather send you to the source than print a number we have not checked.

Game availability changes. A title named here may not be live at every UK casino, and versions supplied in different countries can differ.

Steamworks the Workshop: a Peter & Sons game explained

Steamworks the Workshop, released on 24 October 2024, is a useful example of how the studio builds a game from a small grid. It runs on three reels and three rows with five paylines. If two reels show matching symbols or wilds but no win forms, the third reel respins for another chance. Fill the whole panel with one symbol or with wilds and a random multiplier is applied to the total win.

In the free spins round, the low-paying symbols are removed, which makes matching easier, and multipliers come into play. Small grids with respins tend to feel quick and punchy; each spin is short, and features are the main source of larger returns. As with any slot, the respin and multiplier odds are built into the published RTP, so the extra chances are already priced in. Our explainer on slot multipliers shows how multipliers fit into the overall return.

Style and maths habits in Peter & Sons casino games

Coverage describes the studio’s maths as volatile, and one review notes it has borrowed DoubleMax mechanics from Yggdrasil to power some of its models. DoubleMax is a multiplier system that grows with consecutive wins. When a studio leans on mechanics like that, the result is usually a game where most spins return little and a minority of features carry the bulk of the return.

Here is what that means in pounds. Imagine a session budget of £30 at 30p a spin: 100 spins. In a high-volatility game you might see long runs with small or no returns, and the budget can run out before a feature lands at all. In a lower-volatility game the same £30 tends to last longer but rarely produces a large single win. Neither outcome is predictable; our guide to volatility explains the trade-off.

How Peter & Sons games reach casinos

Small studios rarely sign deals with every casino directly. Instead they distribute through larger platforms or aggregators, which plug many studios into one integration. Trade coverage names Yggdrasil’s YG Masters programme as one of the routes Peter & Sons has used, and reports that its games run on Yggdrasil’s technology. Our Yggdrasil casino games page explains that programme.

Can you play Peter & Sons games at UK casinos?

Only if the casino has added them and the supply chain is approved for Great Britain. Companies that make or supply gambling software for British operators need their own Gambling Commission licence, or must supply through a licensed partner. Our facts file does not hold a register account number for Peter & Sons or Spinart Ltd, so we cannot confirm one here. You can search the Commission’s register of gambling businesses (opens in a new tab) by company name to check current entries.

1. Log in to a UK-licensed casino and pass age verification.
2. Search for a title such as Barbarossa or Steamworks the Workshop.
3. If it appears, open the information screen to confirm the developer and RTP.
4. If it does not appear, accept that the casino does not offer it; do not look for unlicensed sites to find it.
5. Before staking, set a deposit limit and decide how long you will play.

The last point matters. Sites without a UK licence lack the protections British players rely on; our guide to unlicensed casino risks explains what you give up.

UK rules that would apply to Peter & Sons games

Any Peter & Sons slot at a UK-licensed casino must follow the design rules in force since 31 October 2021: no autoplay, at least 2.5 seconds per spin, no turbo or slam-stop, no celebrating a return equal to or below the stake, and a visible net position. The Commission’s online games design consultation response (opens in a new tab) sets out the reasoning. Slot stakes are capped at £5 per spin for players aged 25 and over and £2 for 18 to 24-year-olds.

Scratch cards and crash games are not reel-based slots, so the slot stake limits do not cover them, but the January 2025 extension of the design rules to other online casino games does: autoplay is banned and non-slot casino games need at least 5 seconds per game cycle. Our game design rules page and the table game speed rules page explain how the two speed limits differ.

Peter & Sons compared with similar small studios

The studio belongs to a wave of small studios that compete on art direction and unusual mechanics rather than catalogue size. Avatar UX, which also reached casinos through the Yggdrasil network, built its name on the PopWins mechanic. Just For The Win is a Swedish studio distributed through Games Global. Larger, longer-established names such as Quickspin publish more of their figures and have bigger back catalogues.

Playing unfamiliar studios’ games safely

Trying a new studio is part of the fun for many players, but it is still paid entertainment and losses are likely over time. Keep stakes small until you know how a game behaves, use time reminders, and never chase losses.
