The work I did was also used as the foundation for Poker Keno and Sky Vegas Live Roulette. I supported the developers of these games when they launched on Sky Vegas Live.
The Super Keno application was developed in C in the Open TV API; it was attached at run-time using dynamic linking to Sky's WAP TV browser. The WAP TV browser had some additional API's on top of the Open TV API. The Super Keno application handled key input, real time events, animations and XML request/responses. As there service was using real time updates, the internal state machine was quite complex.
Super Keno is no longer being broadcasted on Sky Digital.
