"Will You Press The Button?" is a Web-based game that allows players to create offers for other players. Each offer usually consists of an appealing benefit that is had at a significant cost, and users choose whether or not to accept the offer by pressing the button.
The website tracks statistics of how many users opted to press the button for each choice. The root of the game is likely Richard Matheson's short story "Button, Button", which was adapted into an episode of "The Twilight Zone." In each version of the story, a couple is offered a large sum of money if they press a button, with the stipulation that someone they do not know will die.
