Any undergraduate student with a valid college ID. Teams may mix members from different colleges unless a specific round states otherwise.

It varies by part. The Coding Competition allows 1 to 3 members, the Cybersecurity Hackathon and the build round allow 2 to 4. The exact range is shown on each event page and enforced at registration.

Yes. TRIALATHON is designed as a progression: everyone starts at Part 1, and shortlisted teams advance to Part 2 and then Part 3. You register per part, and shortlisted teams are invited to confirm their slot.

The Coding Competition runs online. The Cybersecurity Hackathon and the final build round run on campus. Check each event page for the current mode.

Scores are entered by organisers and the leaderboard recalculates ranks from that data on every read. Part 1 uses ICPC-style ranking (problems solved, then penalty); Part 2 uses flag points; Part 3 uses jury scores. The page refreshes automatically while it is open.

Shortlists are drawn from the final standings of the preceding part, with a small number of wildcard slots at the organisers' discretion. Shortlists appear on the site only once published.

They differ per round and are listed on every problem statement: source files for the coding round, flags plus write-ups for the CTF, and a repository, demo video and live presentation for the build round.

One substitution is allowed between parts, and must be requested by email before the registration deadline for that part. Substitutes must meet the same eligibility rules.

Late submissions are not accepted by the judge or scoring platform. Deadlines are shown on each problem statement and enforced in the platform, not by hand.

Part winners come from the final leaderboard of that part. The overall TRIALATHON champion is decided on combined performance across all three parts, and is announced after the final round.
