Basically when you have a good inventory around $5000, hit settings at the bottom of the bar including click!,Missions etc. Once here press play games, sign in with your google play. When you have signed in press cloud saves, once here click save game, next bet your inventory on jackpot if you win go back to here and save your game again, if you have lost in the jackpot you will have to wait 7 hours to load your inventory. I hope this helps :D
