What % of the new money played on a slot machine is paid back assuming a stated 90% payback on each pull?

Barkley Hound asked:


The payback percentage of a slot machine on a single play is usually around 90. This means that if 100 people play a dollar slot machine, on one pull $90 will be given as winnings. Now for subsequent plays part of the money played is won money. My question is, in the long run what is the percentage of the total new money spent that is casino profit? Don’t forget that most players will keep putting their money back in until they have lost their limit. Very few walk away with the jackpot.

   In the long term there are no winnings. 10% of all new money fed to the machine will be lost. That is why they call them one-arm bandits.
   A roulette with one zero is a better bet.

   Play long enough and you’ll lose all your money.
