This page allows you to test any classical strategy for the game described in "Quantum Pseudo-Telepathy Saves the World" [1]. In the game, three players (Alice, Bob and Charlie) are separated by a large distance, and then each is given a smooth boulder or a jagged boulder. The number of smooth boulders will always be three (the 3-smooth case) or one (the 1-smooth case). Each of the players must then make a choice: to keep his or her boulder or to give it back.
In order to win the 1-smooth case, the three players must keep an odd number of boulders. In order to win the 3-smooth case, the players must give back an odd number of boulders.
To test a classical strategy, please indicate what each of the three players will do with a smooth boulder and with a jagged boulder. Each time that you change the strategy, new information is shown about which situations fail. Do not be discouraged if you cannot find a classical strategy that always wins. There is no such strategy!
