The game runs over a fixed number of rounds and the winner has the largest fraction of claims that have been proposed by the winner and that have survived at least one opposition attempt but have never been successfully opposed by others.
Concepts: hypothesis / problem /solution SCG is a two player game, where the players compete for points by proposing and opposing hypotheses to each other. The players compete over a fixed number of rounds. During each round a player proposes challenging hypotheses, and the opposing player has the option to oppose some of them through one of two means: 1.) (refuting) by forcing the first player to contradict its own hypothesis by constructing problems and solutions, or 2.) (strengthening) by refining the hypothesis to make it stronger but not refutable. Concrete examples (problems conforming to the hypothesis) are exchanged to determine which player is correct. The winner is determined at the end of the rounds as the player who has proposed the largest fraction of unopposed hypotheses compared to all hypotheses offered by that player.
