Compared with a round-robin tournament, a Swiss tournament can handle many players without requiring an impractical number of rounds. An elimination tournament is better suited to a situation in which only a limited number of games may be simultaneously played in the tournament. For example, if a tennis tournament had sixty-four players, but only eight courts available, then not all matches in a round can be played at the same time. In a Swiss tournament, each round would have to be divided up into four waves of eight matches each. This would result in a total of twenty-four waves over the minimum six rounds. Conversely, for a single elimination tournament, the first round would require four waves, the next two, and all remaining rounds would consist of a single wave each. Over the same six rounds, only nine waves would occur. Note that the waves format is not strictly necessary, but instead a match could commence as soon as another in the same round ends, but the principle is largely the same.
