This is a very cool idea and I really enjoyed it! I did get caught off guard from the score wheels changing through. I was resistant to try the multiplier for some time since scoring 3 matching numbers would be pretty unlikely. I didn't realize the score wheels would change to fewer symbols after pulling the lever. Something similar happened with the upgrades, I wasn't expecting the wheel numbers to get significantly higher after pulling. Just having the wheels change as soon as the player selects a switch would completely fix that. It's not game breaking though and the game is still very good!
