Tournaments

Which tournaments are on CodeKairo Battles?

The list holds every published tournament of a verified college, club or company that has not finished — open for registration, registration closed, or live now — each with its format, its organizer, its start and the places taken. Open one to read its rules, see who may enter and register; signed in, your own registrations are listed above the rest with their status. Finished tournaments leave the list; their results stay on the tournament's own page and on each player's profile.

The formats

• 1v1 knockout — Players register, check in and are seeded by rating into a bracket. Every match is one problem on a clock, won by the first accepted solution or, at time, by the most hidden tests passed.
• ICPC-style contest — Teams of up to three against one problem set on one clock, ranked by problems solved and then penalty time, with a scoreboard that can freeze before the end.
