What are Swiss Pairings?
Some events in Magic Online are Single Elimination. As soon as you lose a match, you will be dropped from the tournament. The rest of the events use Swiss pairings. In a Swiss tournament, you will continue to play whether you win or lose. You get 3 points for winning and 0 points for a loss. Prizes will be awarded based on how many points you have at the end of the event. Other tournaments may award prizes based on your record after the preliminary rounds. The number of preliminary rounds is determined by the number of players that began the tournament:
I'm in a Swiss event and everyone else is playing but I'm not. Was I dropped?
You're fine! You just got a bye. This counts like a win for the round but you don't have to play anyone to get that win. In the first round, players are paired randomly, with one player receiving a bye if there are an odd number. In subsequent rounds, you are paired based on your record - players with the same or similar records are paired together. If there are an odd number of players in any round, a player is chosen at random from players who have the lowest score and who have not yet received a bye. If a top 8 playoff is used, pairing for the single-elimination rounds generally use a seeding system (1st seed plays 8th seed, 2nd plays 7th, and so on).
