LIT 2025 🔥

LIT (Lexington Informatics Tournament) is a competitive programming tournament for contestants of all levels, hosted by members of the LexMACS club along with many guest problemsetters/testers.

Participants may form teams of up to three, solving challenges together. We'll have an opening ceremony (8/22 10:00am ET), and teams will choose when during the contest window (8/22 11:00am to 8/26 11:00am ET) to start the Standard Round. When the window ends, scores will be compiled and we will release a leaderboard.

We also run a CTF Round, which will be open from 8/23 11:00am to 8/25 11:00am ET with a live scoreboard. Teams have all 3 days to work on it. Additionally, teams with exceptional performance will also receive certain prizes. For more information about the two rounds, please check the contest logistics.

Please join us in the LIT Discord Server for the latest announcements, help, or team formation.

Explore New Formats

Traditional OI format can be boring — you are given some problems in a set amount of time, and you need to solve as many problems as possible. That is why, on top of a standard format OI contest, we have hosted a CTF round since LIT 2021 (learn more about contest logistics). Even if you are already familiar with competitive programming, we promise that the CTF round will provide a whole new refreshing experience.
