Peter & Sons

About Peter & Sons

No other studio in iGaming has a visual fingerprint quite so immediately recognisable as Peter & Sons: the hand-drawn characters, richly textured worlds, and animated symbols bursting with personality.

It’s a look that was developed from day one and has never been compromised, even as the slot studio has grown and its ambitions have expanded.

Founded in 2019 by a small international team of enthusiasts led by Yann Bautista, with headquarters split between Yerevan, Armenia and Barcelona, Spain, Peter & Sons started with a clear philosophy: we don’t just build games, we build worlds.

Looking at almost any release in the catalogue, it becomes clear that the artwork, the characters, the mechanics, and the audio are all designed to serve a singular creative vision rather than being assembled from separate parts.

The studio has brought together artists, mathematicians, and musicians who work in genuine creative collaboration rather than in isolation, and the results speak for themselves.

Peter & Sons Growth and Distribution

Joining Yggdrasil’s YG Masters programme in 2020 gave the studio access to some of the most powerful mechanics in the industry, including DoubleMax, MultiMax, and Gigablox.

Peter & Sons took this in stride, adopting these features and making unmistakably their own. Monster Blox Gigablox, WaterBlox Gigablox, and Dungeon Tower MultiMax showed what happened when the studio’s visual identity met Yggdrasil’s mechanical firepower.

Outside of this, Peter & Sons is also involved in Relax Gaming’s Silver Bullet programme.

With these two partnerships, Peter & Sons gain access to a global distribution network, with their games available at 200+ casino operators around the world. They are also certified in over 15 jurisdictions to meet high industry standards, including iGaming licences from the UKGC, MGA, and AGCO.

Best Peter & Sons Slots

Barbarossa DoubleMax is Peter & Sons most recognisable release by far.

Built around a 16th-century Ottoman corsair and the cascading DoubleMax multiplier system that doubles with every consecutive win, the pirate-themed release offered a 20,000x maximum win and an unlimited multiplier during free spins.

Its sequel, Barbarossa Revenge DoubleMax, arrived in October 2024 with a darker aesthetic, JumpUp and Golden Multiplier modifiers, and a raised ceiling of 30,000x.

Beyond the flagship Barbarossa series, the portfolio spans an extraordinary range of worlds:

• Book of Books is a self-aware take on the oversaturated book genre.
• Xibalba plunges players into Mayan mythology with progressive multipliers.
• Valkyries sweeps across Norse realms with locking wilds and power reels.
• Hammer of Gods pushed a 51,000x maximum win through six reels.
• Rust World is a steampunk cluster pays release with scaling multipliers

So far, the studio has released over 50 titles, distributes across more than 15 regulated markets in over 40 languages.

Volatility sits predominantly in the high range, RTPs average around 96%, and almost every release carries a bonus buy option.

“Peter and Sons are simply one of the best studios in the game right now, full stop. The art style is completely their own and the Barbarossa series in particular shows a team that genuinely understands how to build tension and deliver on it. Barbarossa Revenge is an absolute must-play. ” Mark, Content Editor

“I could look at Peter and Sons thumbnails all day. Everything about their games just feels crafted. Barbarossa Revenge is class, Book of Books made me laugh, and Hammer of Gods genuinely goes off. One of my favourite studios in the industry without question.” Jamie, Slot Streamer & Fruity Slots Founder
