Free The Witch

In Free the Witch, it keeps telling me to use the slot machine, but I don't know how to get to it?

LisaBPeele, first welcome to the forum. Second, there will be no more updates and currently there are lots of bugs in this game. So, enjoy it while you can.
Lastly, in answer to your question - when you lose a level, a slot machine appears at the bottom of the screen. Just click on the handle to "use the slot machine." Good luck.
