Hi all, I have a sugestion. I want to add in in the playroom, a casino game, with a slotmachine, a bar etc. Thanks.

As far as a slot machine goes, Quentin doesn't want games that are too easy for players.
Putting virtual coins into a machine and pressing a single button doesn't require much thought and he wants games that make you apply at least a little brain power.
I hate to break it to you like this but Quentin hasn't taken very many suggestions from the average player.
Probably the closest thing you're going to get to this full-fledged casino game idea is Ponte's casino for the Android platform.
If Android isn't your cup of coffee, DiceWorld for IOS can get you started although you might need an Apple ID to to post your scores to Game Center.
If you don't have a mobile device of any kind, you can always try Jim Kitchen's casino game for Windows.
Hope this helps.

yeah the slot machine is slightly to easy.
However, we do have blackjack, which is a casino game.

though i do agree with tle slot machine being too simple for players, i would put forward a chip-orientated game of some sort...

we do have 2 games like that already. One already spoken of the other is Poker.
