“The priority is to prove the model properly; make sure the games perform and demonstrate that it works commercially.”

The proposition is already being tested commercially. Live casino supplier Eeze has become the first supplier to utilise Studio in a Box as it looks to expand its proprietary content into slots. Using Yggdrasil’s framework also gives Eeze access to its wider distribution network.
