There are four contestants in a cake-decorating contest in which all of the decorating work is to be done during the two-hour contest. All contestants take into account what they believe to be the most likely choices of the other decorators as input into their design decisions. This type of "game" is closely related to a

simultaneous-move game because all players decorate at the same time.

positive-sum game because the winner receives a prize.

dominant strategy game because only one decorator will win.

sequential-move game because designs are thought through before decoration begins.
