ZeusPlay: Greek Slot and Lottery Game Studio

ZeusPlay develops both lottery and casino games and supplies complete portfolios to online and land-based operators. Its team has more than two decades of experience in the gaming industry.

A 360-degree production model

Everything is made in-house. Graphic designers, animators, mathematicians, front-end and back-end developers and sound designers work together from first concept to final audio, so each game feels coherent and immersive.

New technology stack

In 2022 the studio rolled out new game and web server technology, client technology and databases, all built from scratch with current industry tools. The rebuild lets ZeusPlay produce games more efficiently, serve more partners and reduce the risk of problems during traffic peaks.

The product line now covers 60+ HTML5 slots for online casinos and three standalone instant-win numeric games for retail shops: Lucky Picks, Balkan Keno and Lucky Spins.

ZeusPlay is owned and managed by CEO Antonois Zlatanos. Revenue figures have not been published.

Key people

• Antonois Zlatanos, CEO
• Katerina Katrakylaki, CFO and Commercial Manager
• Evangelos Matselis, Product Manager

The 60+ HTML5 slots run smoothly on every device type, and many of them use mechanics designed to keep players involved.

• Haunted Walker 2: an expanded wild covers a whole reel and then walks to the next reel on each spin, creating more chances for winning lines.
• Highway Rebels: an interactive bonus where players choose their feature, such as random reel wilds, sticky wilds or random wilds.

Average RTP across the slots sits between 94% and 96%, and volatility levels vary so operators can cater to different player types.

Academic partnership

ZeusPlay works with the University of Macedonia in Thessaloniki on game mathematics. The collaboration has produced advanced mathematical tools that help the studio build well-balanced maths models for fairness and player satisfaction.

Several ZeusPlay slots have performed strongly for operators. Three examples:

Hot Diamonds 100 Dice

A classic fruit-machine style slot where every symbol sits on a die, like those used in craps. The 5x4 grid has 100 paylines, low-to-medium volatility and 95% RTP. A wild that completes a win expands to fill its reel, and five scatters on a line pay the top prize of 2,000 EUR.

The Zodiac 12

An astrology-themed slot with the twelve star signs on 6 reels, 4 rows and 30 fixed paylines. Its highlight is the 12th Spin: every twelfth spin drops a random number of wilds onto the grid. Three or more Bonus symbols award 12 free spins with prize multipliers and random wilds.

Wild Pink Cadillac

A summer beach slot with bikinis, sunshine and plenty of features, played on 5 reels, 3 rows and 20 fixed paylines. Wilds appear on every reel, replace all symbols except the scatter and carry multipliers. Scatters land on reels 2, 3 and 4 and unlock four free spin bonuses, each with its own multiplier and volatility. RTP is 97%, and the game is highly volatile.

ZeusPlay builds its own game and web server technology, which keeps the software stable at peak times, and develops its maths models with scientists from the University of Macedonia.

Slots and lottery games share an HTML5 foundation, so they play smoothly on any mobile operating system and run without problems inside casinos' native apps.

On top of the in-game bonuses, ZeusPlay titles pair well with our bonus system. It offers loyalty programmes with custom levels, deposit bonuses, tournaments and rakes with more than 50 parameters, plus other options available when you connect ZeusPlay through us.

SSL encryption and firewalls protect the integrity of ZeusPlay games. The studio's random number generator has been licensed and certified for fairness by iTechLabs, GamingLabs and the Hellenic Gaming Commission, and all of its games are licensed by the Commission (EEEP).

ZeusPlay has not yet won a major iGaming award, but it was nominated for the Slot Legacy award at the CasinoBeats awards in 2023.
