Test the payout of your machine.\n\n If you are, stay put! It could be a loose slot machine! If not, move to another machine. For example, if you spend about twenty dollars at a machine over half an hour and only get about ten dollars back, that's probably not a loose machine.
The terms "tight" and "loose" in the context of slot machines refer to the payout percentages. A "tight" slot machine is one that has a lower payout percentage, meaning it pays out less frequently but in larger amounts.
