Peter & Sons: art-led slots and compounding multipliers
Peter & Sons is a 2019 studio that does everything in-house — art, animation, sound and maths — and is recognisable on sight. Behind the illustration sit mechanics like DoubleMax, where the multiplier doubles on every cascade.
The studio
Who Peter & Sons are
Peter & Sons launched in 2019, trading as Spinart Ltd under a Malta critical gaming supply licence. It has 78 slots plus scratch cards and instant-win games, and distribution to more than a thousand operators across 15+ jurisdictions.
The studio’s stated model is fully in-house production — art, animation, sound design and maths under one roof — and it shows. There is a consistent hand-drawn, high-contrast cartoon style and strong character design that makes a Peter & Sons title recognisable across completely different themes. Their pitch is creative ownership over trend-chasing, and the house sound design is distinctive enough that they put the soundtracks on Spotify in December 2025.
Under the art sit real mechanics. DoubleMax doubles the win multiplier on every consecutive cascade, so a long chain compounds geometrically — which is how Barbarossa reaches a 20,000x ceiling. Step Multiplier in Abrakadabra advances a stage at a time instead of incrementing flatly.
Commercially the standout is Italy, where the studio claims reach into roughly 70% of the market through operator partnerships. That is their own figure, but the Octavian Lab deal and Eurobet launch support the direction.

What makes it different
What Peter & Sons do differently
An art direction that functions as a brand, plus three named mechanics that are genuinely different from each other.
In-house art direction
Art, animation, sound and maths are all produced internally, which is why the titles are recognisable on sight across unrelated themes. In a lobby of two thousand games, being identifiable at thumbnail size is a commercial asset, not a vanity one.
DoubleMax
The multiplier doubles on each consecutive cascade rather than incrementing. That is compounding rather than additive, and it is exactly why the Barbarossa line carries 20,000x ceilings where a flat-increment game would not.
Step Multiplier
In Abrakadabra the multiplier climbs one defined step per consecutive cascade. A more controlled escalation than DoubleMax, which gives the studio two distinct volatility feels from the same cascade base.
Power Reel
In Valkyries a dedicated reel selects between dropping wilds or locking wilds, each granting respins. The player does not choose — the reel does, which keeps the round unpredictable.
Where it runs
Where Peter & Sons games are available
Italy is the standout. The studio states reach into roughly 70% of the Italian market through operator partnerships, supported by an Octavian Lab deal and a Eurobet launch. That is a studio claim rather than an audited figure, but the direction is clear.
Regulated Europe broadly: Spain, Germany (entered March 2026), Denmark, Sweden and Greece. A February 2026 multi-market agreement with bet365 is a meaningful signal — that operator does not integrate lightly.
Expansion beyond Europe runs through Latin America via Relax Gaming, Ontario via Ellipse Entertainment from March 2026, and the UK and South Africa via Hollywoodbets from July 2026.

FAQ
Peter & Sons — common questions
Video slots — 78 of them — plus scratch cards and instant-win games. No live dealer, bingo or crash. Everything is produced in-house: art, animation, sound design and maths.
Abrakadabra is the signature hit. Barbarossa DoubleMax, Valkyries, Book of Books and Kaiser are the other recognisable titles. Abe’s Saloon (May 2019) was the debut, and Soapranos, Cyber Runner and Roadquake are current releases.
A mechanic where the win multiplier doubles on every consecutive cascade rather than incrementing by a flat amount. Because it compounds, a long cascade chain escalates fast — which is how the Barbarossa line reaches a 20,000x maximum.
In Abrakadabra the multiplier climbs one defined step per consecutive cascade instead of doubling. It gives a more controlled escalation than DoubleMax, so the studio gets two distinct volatility profiles from the same cascade base.
Because all the art, animation and sound is made in-house rather than outsourced. The result is a consistent hand-drawn, high-contrast style with strong character design that is recognisable even at thumbnail size — genuinely useful in a lobby of thousands of games.
Malta (MGA/CRP/681/2019) plus the UK, New Jersey, Ontario, Denmark, Sweden, Greece, Italy, Germany, Spain, Brazil and Argentina — the studio states more than fifteen jurisdictions. Only the Malta number is published.
