Rules for the International Solving Contest (ISC)

  1. Event: The ISC is a solving competition appointed by the WFCC for individual solvers taking place on multiple locations worldwide on a Sunday at the end of January concurrently in all participating countries.
  2. Organisation: at the WCCC of the preceding year central controller(s) are appointed by the WFCC delegates who will take the overall responsibility of the contest.
  3. Admittance: For the admittance of each participating place a reliable local controller with email address has to be appointed for the responsibility of organising the local tournament, preferably by the local controller of the respective country; otherwise the central controllers decide about the acceptance of local controllers.
    There is no limit for the amount of local competitions and multiple places per country are possible. Solvers are admitted in any local competitions, also in other countries.
  4. Categories: The competition comprises three solver categories:
    • Category 1 for experienced solvers, but open for all solvers
    • Category 2 for inexperienced solvers with no rating or with an active, non-active orhalf-rating of less than 1700
    • Category 3 for youth not older than 13 years in the year of the competition

    Separate results are recorded for youth, females and seniors. For Category 1 only results of solvers will be rated. However, for all solvers no norms for titles are possible.

  5. Begin: The start of the contest should be at 11 a.m. CET (Central European Time) in all countries. Central controllers can allow a different begin of the contest for Asia and the Americas and an earlier or later begin of one hour at most for all other countries.
  6. Rounds: The rounds of the contest last two hours for all categories. 
    There are two rounds for category 1 and 2 with a break of at least half an hour with a maximum of one and a half hour between the two rounds. For category 3 there is one round only.
  7. Modus:
    • Category 1: for each round a 2#, 3#, n#, eg, h# and s#
    • Category 2: for each round two 2# and one 3#, n# and eg and in one round a h# and in the other round a s#
    • Category 3: four 2#, a 3# and an eg
  8. Rules and Appeals: General applicable solving rules of the WCSC/ECSC apply accordingly. Appeals by solvers have to be sent to the central controllers who will decide in the first instance. In case of disagreement a 3 man committee with members of the WFCC Solving Committee will be appointed for the final decision.
  9. Tools: (technical tools used by central and local controllers)
