Will 10 losses in a row guarantee a payout on the next spin of a slot machine? The only way to find out is to play!


An ATM (“Automated Teller Machine”) resembles a slot machine in many respects: the user fiddles with a set of controls for a bit, and money (hopefully) comes out in the end.

Additionally, humans have a fascination with gambling, and will often happily hand over a small amount of money for a small chance of a much larger sum.

One of the problems with a slot machine is that, over time, a user who continues to play will (eventually) go bankrupt due to the house edge.

But we can fix this and increase bank profitability at the same time.

The proposal: “ATM Slot Machine”

In these proposed ATMs, when the user inserts their card to make a withdrawal, the ATM would have a button that allowed it to operate exactly like a slot machine; the user would have an opportunity to deduct extra money from their account, and if they won, the ATM would dispense their winnings in cash right there.

The user could be limited to (say) 5 plays per day, to prevent long lines from forming behind compulsive gamblers at ATMs.

Because the user is withdrawing their own money no matter what, they would always “win” in the sense of receiving a positive amount of money from the ATM (even though a losing player might only get $40 in cash from a $50 withdrawal—which is not too dissimilar from the fees charged at many ATMs, so there may be less customer resistance to this new type of ATM than would normally be expected).

If slot-machine-ATMs violate any laws in your jurisdiction, you should protest immediately.

PROS: Adds a sense of adventure and excitement to a mundane ATM withdrawal.

CONS: May be illegal in your state or country.
