What is this mailer worth?

Free play, food and the drive all have a dollar value. Add them up before you go, and see how fast extra play eats the offer.

The offer

Why free play isn't worth face value

Free play has to be bet once before it turns into cash, and the machine keeps its usual cut. $100 on a slot that returns 90% is worth about $90.

Play it through once, then cash out

Whatever the free play wins is real money. Keep betting it and you're gambling your own cash at the house's normal edge.

Watch the extra play

Betting $1,000 of your own money on a 90% slot costs about $100 on average, which can wipe out a $100 offer by itself.
