DragonByte Coding Challenge 2026
Wincent
📌About the Event
DragonByte Coding Challenge 2026 is a global algorithmic programming competition by Wincent for developers, engineers, and competitive programmers who enjoy solving hard coding problems under time pressure. The challenge tests algorithmic thinking, edge-case handling, optimisation, and decision-making through multiple rounds, ending with an on-site final in Bratislava, Slovakia for the top eligible participants

🎯 Eligibility & Rules
- Who can participate:
- The first two online rounds are open globally.
- Full-time employed participants are allowed, except Wincent employees and people living in the same household as them.
- On-site finals eligibility is restricted to participants from eligible regions/countries listed by the organizer.
- Competition rules:
- Participants solve one or more algorithmic problems in each round.
- Participants must design algorithms, write programs, compute outputs for given datasets, and submit the outputs.
- Any programming language can be used because only the program outputs are judged.
- Source code must be submitted with the output file, and deliberate code obfuscation is prohibited.
- Simple AI tools for boilerplate coding are allowed, but using AI to solve the logic of the problems is treated as cheating.
- Round-wise selection:
- In the Qualification Round, participants must reach the announced score threshold to advance.
- If fewer than 1,000 participants reach the threshold, the top 1,000 participants with a positive score advance.
- In the Main Online Round, the top 20 scoring and eligible competitors receive invitations to the final round.
- Evaluation process:
- Submissions are graded according to each problem’s scoring rules.
- Datasets may be labelled public, private, or secret, depending on when the result is shown.
- Participants can make up to 20 submissions per dataset; each resubmission adds a 15-minute penalty.
- Rankings are based on total score; ties are broken by total solving time plus penalties.
