About Peter & Sons
Peter & Sons is an independent slot studio founded in 2019. The company was set up by Petar Vasiljevic and Yann Bautista, with Petar's sons Aleksey and Ignat also part of the leadership — which is where the name comes from. The core team draws talent from Armenia, Spain, and several other countries, with offices in Armenia and Spain.
The studio joined Yggdrasil's YG Masters program in 2020, which gave them early access to patented mechanics like Gigablox, DoubleMax, and MultiMax. In 2022 they signed a Silver Bullet deal with Relax Gaming, and in 2023 SkillOnNet made a strategic investment in the company. Distribution partners now include EveryMatrix, Playtech, BRAGG Gaming, Light & Wonder, and IGT — covering over 1,000 operators across 15+ regulated markets.
Peter & Sons holds an MGA license (MGA/CRP/681/2019) and is certified by the UK Gambling Commission, Swedish Gaming Authority, and a dozen further regulators. All games are built in HTML5 and run on desktop and mobile.
Awards: Best New Provider at the SlotsWise Gaming Awards 2021, Rising Star Game Developer of the Year at the Kongebonus Awards 2025, and Rising Star of the Year at the International Gaming Awards 2026.
What Peter & Sons Games Are Like
The studio's signature is a hand-drawn art style — fully built worlds, not recycled templates. Games skew high volatility, with most RTPs landing between 96.00% and 96.70%, right at or just above the 96% industry average.
Recurring mechanics include cascading/tumble reels, Gigablox (oversized symbols filling up to 6×6 spaces), DoubleMax (wilds that double a multiplier on each cascade), and MultiMax (growing multiplier wilds). Free spins and respins are standard across most titles, and several games include bonus buy where regulations allow.
Themes run wide: Vikings, Wild West, ancient Rome, zombies, magic, circus, feudal Japan, and more. The Barbarossa series spans multiple entries across different mechanics. Ghost Father and Ghostfather Awakened show the studio building on its own IP across sequels.
