Offline finals: Registration process

  • The process of filling up the offline finals' slots is the same as last year's process. We want to encourage solvers who aren't near the top yet but still want the experience of an offline final. The eligibility criteria is that the solver must have participated in at least 4 of the 6 online rounds ('participated' here means achieving a non-zero score in the round) OR reaches the top 60 within two or less rounds. After Round 6, we will ask the solvers from 1-30 first and give them a week to confirm participation. After this, registrations will be open to participants from 31-60 for a week, and then it is open to everyone 'eligible' by the criteria above, till we get to 60 participants. After that, due to venue restrictions, we will be ending registrations.
  • The points total from the online rounds (i.e. the best 4 rounds for each participant) will be considered to give some base points to finalists to start with in the offline round. Specifically, the finalists will start with an average of their best 4 normalized scores.
  • If online round organizers participate in the offline finals they will automatically get the same base points as the top solver of the online rounds

Prizes

All players who appear for the offline finals will receive a certificate.
Additionally,
  • Top-3 players at the offline finals will be awarded medals / trophies.
  • All players at the offline finals Under-21yrs and over-50yrs will receive special prizes.
