TwoRound

Tworound is a term used to describe a process that unfolds in two distinct rounds to determine a result. It is used in several domains, notably political elections, sports competitions, and other decision-making workflows. The essential idea is that a single round is insufficient to reach a final outcome, so a second stage allows for additional information gathering, coalition-building, or reconciliation of divergent preferences.

In elections, two-round systems (often called runoff or second-round voting) operate as follows: if no candidate achieves the required threshold in the first round—commonly an absolute majority—the top two candidates proceed to a second round, where the winner is determined under the system's rules. In some variants, more than two candidates may advance to a runoff, or a top-two structure may be used depending on jurisdiction. The second round typically concentrates votes around the leading contenders, potentially altering support dynamics that emerged in the first round.

In sports and competitions, a two-round format can describe either two-stage knockouts or two-legged ties, where teams or participants compete in two rounds and the aggregate result or second-round outcome determines the advancing team or final winner. The exact rules vary by sport and league, but the common feature is that the contest spans two separate rounds before a final decision.

Beyond games and elections, tworound methods are used in decision processes such as grant reviews or performance evaluations, where an initial assessment is followed by a second, more focused round of consideration or appeal.
