Zonelock Games: Creator of Mahjong Exchange

Zonelock Games designs and develops casino software on a small scale. It is not widely known, largely because it has no corporate website, and it relies on distribution partners to bring its games to market.

Its catalogue is still short, but the games have been licensed and verified through those partner networks, so players and operators can trust that they are fair and safe.

Base and partners

The studio is based in the Isle of Man, a long-established gambling hub, and is registered under Isle of Man gaming law. It has chosen Ingenuity Games as its development partner, a move that should lead to more releases over time.

Zonelock has released two titles so far.

Mahjong Exchange

The studio's most popular game is built on traditional Chinese mahjong, where players match tiles to complete a legal hand. Zonelock adds a twist: the exchange option lets players swap the randomly selected secret tile for another face-down tile in the array. This gives players more control without changing the odds. RTP is 97.06%.

Royal Realms

Released in 2016, Royal Realms is a classic-style video slot with five reels. Free spins and a jackpot bonus game are among its features.

Our casino API is a quick way to add something different to your lobby. One integration brings in Zonelock's games, and future releases can be switched on as soon as they become available, alongside 3,600+ games from 170+ studios in our game aggregation catalogue.
