The ultimate designing and programming tournament.




Is happening in now.



About The Topcoder Open

The Topcoder Open (TCO) is our annual online and onsite tournament to celebrate and reward the community. TCO encompasses every day competitions at Topcoder and adds points to them. While you’re competing, you’re earning TCO points and more potential prizes as well as trips to the TCO Finals held in the United States!

The ultimate programming tournament is back again for another year. We can’t wait to see the live competitions go down, the innovative speakers take the stage, and see who will reign as the new champions!

How it works

Register and submit for any TCO eligible challenge. Win first place for that challenge and earn the prize money. You also would win a certain number of TCO points for earning first place.

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 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 Onsite events

The TCO Onsite Finals in the USA brings great honor and excitement to those who qualify to attend. TCO Finalists enjoy being treated like VIPs and deserve all the recognition they get.

As a TCO Finalist, you get an all-expense paid trip to the USA event, the opportunity to compete live, and become a Topcoder champion. Each year the TCO Finals are held in the USA.

TCO now has smaller 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 or two day events including some form of competition with prizes (for example, a hackathon), food and drink, networking opportunities, and fun.
