Ladbrokes spoke with Microgaming. Microgaming mentioned that converting games to flash play is reviewed on a case-by-case basis. There is no current ETA on when Microgaming will have the conversion of the Osbournes slots to flash play. This is the same for all Microgaming operators.
So just regularly keep your eye on Ladbrokescasino.com for the flash play version, as they will be one of the first casinos to get their hands on it.
