Practice on Ouroboros CTF, open all year

Ouroboros CTF is CTF7's practice event. Its challenges stay open all year, so you can solve them between live events at your own pace, with no clock running.

Launching soon Ouroboros CTF is not open yet. This page will link straight to it on launch day.

Ouroboros CTF Launching soon

An always-on CTF is a capture the flag competition that never closes. Challenges stay online year-round, so you can solve them whenever you have time, without waiting for an event weekend. Ouroboros CTF is CTF7's always-on event, listed alongside the timed competitions on the CTF7 events page.

Always-on practice vs a timed event

Both use the same idea: find the flag, submit it, score points. What changes is the clock, and that changes how you learn.

You need both. Practice alone won't teach you to triage ten challenges in the first hour of a live event, and live events alone leave little time to understand why a solve worked. Read what a CTF is and the main formats if these terms are new.

For clubs, faculty and organizers

A college CTF or a club event is a few hours once or twice a year. Your members need somewhere to train in between. Once Ouroboros CTF is live, you can point them to it between your own events, then run the event itself on CTF7: one free event a year for up to 50 participants, or Standard at ₹9,999 per event for up to 500, which adds dynamic flags, anti-cheat, hints and container challenges. For a season of rounds, Organization Starter (₹999 a month) includes two events a month. Lecturers can also start from the free classroom CTF kit.

Can I use Ouroboros CTF to train for a college competition?

That's what it's for. Regular practice between events builds the habits you need on competition day. Pair it with the beginner roadmap and join a live event on the events page when you feel ready.
