Final Battle - 12

Could you clarify for newbies what a "mini-double" is? In the group, do we play 3 games – each player against every other player, resulting in a total of 3 games, or just 2 games in total?

In the first game, you play against the player who was randomly selected. In the second game, you play against the player who played in the group in the same way as you. And in the third round, two players with one win and one loss meet. After the second round, one player will have 2 wins and will advance, while another will have 2 losses and will be eliminated.
