Register and submit for any TCO eligible challenge. Win prizes and TCO points to get you up on the leaderboards.


Each competition for a certain time frame would enable you more opportunities to earn TCO points. At the end of the TCO stage, your total points could be high enough to earn you a trip to the onsite TCO finals in the USA or additional prize money.

The TCO takes place online with points accumulation for Development and Design Tracks and online elimination-style rounds for the Data Science and Algorithm tracks. After all the competitions online are completed, the top performers from each track win prizes and trips to the USA TCO Finals to compete, network, and meet other members and admins.


TCO also includes regional events around the world. The goal of these regional events is to bring the TCO to more Topcoder members.

Regional TCO events are one day events including competitions with prizes (for example, a hackathon), food and drink, networking opportunities, and fun.


What OTHER MEMBERS say about Topcoder

If you check the TCO interviews most of us would say that we are not going there to win but to meet the others, so I don’t really care about, I’m sorry to say, the competition. I wouldn’t win anyway and it freaks me out. I go there because of you guys, to meet you. It’s such a nice feeling to have, this kind of friendship, and it’s amazing that we are competing against each other. There are no hard feelings, no negative feelings besides that. It’s really nice, I don’t know how Topcoder does that.

I read on social media about the TCO event and was curious about how to qualify for it, so I joined a challenge and got a 3rd place in my first challenge. It gave me an adrenaline rush and it was my first love with Topcoder.
