It consists of a special deck with five suits of eleven cards each, numbered from 1 to 10 plus a joker. In the first round, players receive a card and try to guess whether they will win or lose that battle, after which they compare their cards.
In subsequent rounds, players will receive the equivalent number of cards (2 for the second round, 3 for the third, and so on) and must guess how many battles they will win or lose in that round. Players who get it right will receive 10+the round number in positive points (11 points in the first round, 12 in the second and so on), those who get it wrong receive an equivalent negative score.
The winner is the player who scores the most positive points or the fewest negative points, if everyone scores negatively.
