You and your classmates each have $10.0 in the bank. The bank keeps 100% of all deposits on hand as reserve.

Each of you decides independently and simultaneously each round whether you want to withdraw your money or not.

Regardless of how many players withdraw their money, the bank remains solvent and the players who withdrew in that round get their deposit of $10.0 back. If you decide to leave your money in the bank, you will get your initial deposit of $10.0 back as well as $10.0 of interest.
