Main regulations for a physics fight

  • In each physics fights three (or four) teams take place and in turn take the roles of reporter, opponent and moderator (and observer). Read more about the roles on our How to play? page.

  • In each physics fight, each team has 3 non-penalised tactical rejections and 1 permanent rejection. In the first fight, one more tactical rejection is allowed. After using all the rejections, each additional rejection is stored as permanent and reduces the reporter coefficient on 0.2: 2.8, 2.6, 2.4….

  • The penalty coefficient is preserved for the semifinals.

  • Each team has a one-minute timeout per physics fight, which can be taken if not interrupting other teams’ monologue.

  • The top team after the selective fights makes it straight to the finale, 2-7 places form two semifinals: 2,5,6 and 3,4,7.

  • The Opp cannot challenge a problem which a) was permanently rejected by the Rep earlier; b) was presented by the Rep earlier; c) was opposed by the Opp earlier; d) was presented by the Opp earlier. The rules are lifted in the order d), c), b) and a).

  • Each team member can make it to the stage only twice for normal fights, and once for the finale.
