I’m not a Python expert, but I believe you ran the money -= 5 in an if statement, this will probably not affect the money variable after the if statement is finished.

      money -= 5 
      roll1()
      roll2()
      roll3()
      checkwin()

the money doesn’t subtract 5 after rolling the slots

the following code works because previously, if a function is called and it tries to edit a value that’s not defined in the function, it’s not affected outside. So using global var_name will cause it to be edited “globally”
