  • You can compete individually or as a team. If you choose to compete as a team, you may only submit answers from one account.
  • Teams may use the internet as well as past code to reference documentation, algorithms, and syntax. However, teams are not allowed to copy and paste.
  • Team members may be of any age and capability to compete. (Every team member must be in high school for the team to be eligible for prizes.)


  • Each challenge has a pre-determined score.
  • Your team's score depends on the number of test cases that your team’s submission successfully passes.
  • If your team submits more than one solution per challenge, then the team’s score will reflect the highest score achieved.
  • Teams are ranked by score. If two or more teams achieve the same score, then the tie is broken by the total time taken to submit the last solution resulting in a higher score.
