LIT 2026 🔥
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. Teams will choose
when to start the contest window (7/31 11:00am to 8/4 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 8/1 11:00am to 8/3 11:00am ET
with a live scoreboard. Teams have all 48 hours to compete. Additionally, teams with exceptional
performance will also receive certain prizes. For more information about the two rounds, please
check the contest rules.
Please join us in the
LIT Discord Server for the latest announcements, help, or team formation.

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 . Even if you are already familiar with competitive programming, we promise that the CTF round will provide a whole new refreshing experience.
