You need to make your server authoritative over the clients. Which means you need to move the logic that controls the slot's position  and player coin counts onto the server side if it isn't there already.


Here's a quick timeline of events:

  1. User pulls down lever or whatever to start the slots spinning. Start spinning animations.
  2. Client send request to server for final resting slot positions. Keep it simple request like "getPositions" or something.
  3. Client receives resting positions from server and resulting player coin count from server.
  4. Slots animate to positions received from server and update coin count display.

Basically you never want to have to trust the client for ANY information. There are a few exceptions like user login/forms.
