Testez qui a une meilleure vision de loin et une meilleure réactivité entre deux joueurs.
This game is to test who has better distant vision and responsiveness between two players who stare at each other's phone screen from a distance over 2 meters.
Both phones should be paired through Bluetooth. Before the play, player A ensures phone A acts as Host which listens to initial connection from phone B, and player B ensures phone B acts as Client that makes initial connection to phone A.
Two players stand at least 2 meters away from each other, holding a smart phone near the chest, with the screen facing the other player. Player A with phone A reads what displayed on Player B's phone, and wipes the screen of phone A according to direction of the opening of optotype E or C. Likewise, Player B with phone B reads what displayed on phone A, and wipe the screen on phone B.
The player who can read the smallest optotypes with less mistakes and at less time consumed will win.
