Hey there! LexMACS (Lexington Mathematical Computer Science club) is proud to announce that LIT (Lexington Informatics Tournament) is back for 2025!

LIT is composed of 2 rounds: the standard round and the Capture-The-Flag ( CTF ) Cybersecurity round. The standard round is a USACO-style team contest with 8-10 problems and a 3-hour contest window. The CTF round will rely on contestants’ knowledge of computer security and general problem-solving skills to complete challenges and locate a "flag" for each. Some of our problem-setters and testers include EmeraldBlock, jay_jayjay, C0DET1GER, eggag32, Jasonwei08, hihitherethere, Mishazher, Furyna, RandomChicken, and gg_gong.

Participants may create teams of up to 3 members! You can choose to start the standard round at any time during our 4-day contest window (August 22, 11 am ET to August 26, 11 am ET). You can also solve challenges from the CTF round at any time between August 23, 11 am ET and August 25, 11 am ET. For more info on LIT logistics, visit https://lit.lhsmathcs.org/.

Furthermore, we will have over * $20,000 * worth of prizes for teams with superb performances, as well as some secret prizes. Top 8 teams from both the standard and CTF rounds will receive cash prizes! We also have cash prizes specific to both college/post-high school and middle school students, along with game night cash prizes! Regardless of your skill level, we promise that the contest will provide something exciting and refreshing!
