In order to access additional options, select a Slot, next tap and hold on the bet limit tile (Beginner, High Limit or High Roller) until a pop-up will appear.
Start a private game - play alone or with friends! Strangers won't bother you in that mode.
Remove the game from the device - As you know, you need to download a small package of data when you are trying a new table or slot. After a while, all the data may take up a lot of space on your device memory. Don't worry, you don't need to uninstall the whole application! You can remove an individual slot machine or table.
