Two players score over 300 minus points at the same time. Who has lost?

According to the official rules of the game, only the winner of the game receives the points of the other players at the end of a game round. These are credited to him as plus points. The first player to reach 500 points wins the game. Since only one player can win each round, only one player will receive 500 points.

However, it is also usual to count the points of your own hand as minus points. The game ends automatically, just as a player reaches the 300 or 500 points mark (this is determined in advance). The player with the fewest (minus) points has now won the game. All other games are ranked according to their score.
