are ranked according to their victory points. Ties are broken by considering the sum of the current victory points of their opponents. In the next round, neighboring teams in the ranking play each other. In case they have played each other in a previous round, adjustments to the rankings are made. After five rounds of Swiss draw, the top 8 teams play three playoff rounds to determine the final placement of the teams. All other teams continue with the Swiss draw in the remaining rounds. Wargames The International Wargames Federation, the international body for wargames, uses a Swiss system for all its tournaments. For its Swiss implementations, players receive three points for a win and only one for a draw and no player can play against another player more than once. There is the further proviso that no player may play against another player from the same country in the first round as long as no one country has 40% of the entrants. For national championships such rule is amended to read that no player can play against a player from the same club in the first round as long as no one club has 40% of the entrants. Yu-Gi-Oh! Trading Card Game Konami Digital Entertainment of the United States uses proprietary software for their sanctioned and official tournaments. Konami Tournament Software (KTS) is what is supplied to the Tournament Organizers to run each tournament. The software utilized the Swiss system similarly to Magic: The Gathering—3 points for a win, 1 for a draw, 0 for a loss. Konami's official tournament policy dictates how many rounds are played based on the number of participants. After the set number of Swiss system rounds are complete, there is generally a cut to advance in the tournament. This is then played as single-elimination until a winner is declared.
