The default map is 8mm6.
With mutual agreement, you can play 8mm6a, Mini-Nostalgia, or Jebus.
In the first round, the player who goes first in a pair scratches off the top one.
Then, the right to go first will be determined by drawing lots and
marked with small ones.
Losers in the upper bracket fall into the lower bracket, where the game is played until elimination.
The winners of the brackets compete for the Medal.
Moreover, the finalist from the upper bracket only needs to win once,
but the winner from the lower bracket needs to win twice
