What are the game rules?

The Stack Game consists of a stack of TLOS which is sent to a simple smart contract. Everytime some one stacks TLOS, the stack grows. The last player who stacks TLOS in the end will be able to payout the whole stack for themselves (everyone will be able to hit the payout button, if ever possible).

In order to determine the last player and to make sure everyone has enough time to be that last player, the smart contract automatically adds a 'waiting time' once someone stacks TLOS. After that waiting time passed, the last player would be theoretically able to pay out the whole stack. But since anyone can stack new TLOS in the meantime, the waiting time automatically extends. See in FAQ how the smart contract calculates the waiting time based on the stacked amount.
