The Casino

Would someone please tell me where the key is and the key card to open the glass that holds the rose and the King of diamonds?

the gambling machines
between the first and second
is the pass

I said it wrong.
You need to find three coins in the slot machine to stop and then pass it out

i have the keycard and I retrieved the the king of diamonds but now i am not able to find a ruby and the last purse, i tried using the compass to help me find it but it didn't indicate anything.
any ideas
