CTC Scoring system

The scoring system and formula are exactly same as last year.

  • 60 minutes allowed to solve the Tapa puzzle after you start
  • 2 minutes penalty for each wrong submission
  • 15% time penalty for each late day (maximum 2 late days are allowed – so a puzzle can be solved upto 72 hours after it is uploaded)
  • Each puzzle has its own points, which is computed from solving times of top 10% players on that day.
  • Each player gets points for solving a puzzle based on own solving time and others’ solving times. Exponential distribution is used.
  • Total points for a player is sum of puzzle points over 35days.
