I don't think so but they have a direct avenue to advertise new games in CandyCrush to millions of players.

Their numbers imply that not only is Candy Crush much bigger than their other games, it is more effective per-user in engagement and revenue as well. So they run a real risk (which they acknowledge in the filing) that dilution of their player base with more games in the same genres may actually hurt their business. However, cross-promoting games in different genres will be much less effective.
