BET PET is an entertainment device for at least two players. The operation of said device is very simple. It consists of a mechanism that enables a choice to be made between 4 possible numbers (0, 1, 2 and 3). Each player chooses one of these 4 options and makes a prognosis on the possible total of the choices of each player. The player with the correct prognosis wins. If there are no correct prognoses, the game is played again. The model is based on a hand-held device that can be used to play the game, with digital versions for mobile telephone and Internet platforms suitable for the future development of the game and growth of the ludic activity.
