We're wondering where they are too. They were supposed to be in The Concourse and the Roulette room today, but I'll post something when we get an official word.
EDIT: It looks like with the delay and confusion of 1.75 our update to The Casino got pushed back in both NA and EU. We're sorry that our new game isn't available. Looks like it will be next week for the slots to arrive. If anything changes we'll let you guys know.
Awww, sad to hear the new slots were delayed. I was really looking forward to playing them after work tonight. In any case, I'm glad to see the new outfit made it! Thanks for the update and new content DL!
