The IOCCC announced winners for its 29th annual programming competition, maintaining high submission volume and quality levels similar to 2024's contest despite being only the second year after a four-year break. Contest organizers documented and improved their judging process, from submission closure through winner selection and website updates. Winners will be presented on the Our Favorite Universe YouTube channel, with individual segments linked to each entry's page.
