The casino in Xscape looks set to open this autumn.
Work has been going on behind huge screens at the former City Limits site for more than six months as Aspers prepare to move in.
The gaming giants are expected to be handed the keys to the venue in April when they can start moving in.
When finished, the complex will house 150 slot machines, 30 gaming tables, 27 screens showing sport from all over the world, a restaurant and several bars, creating 250 jobs in the process.
Aspers will also give £500,000 a year to Milton Keynes Council to ‘support local comminities’.
