The 13th annual FLARE-On contest has come to a close. This year proved to be a pivotal year for the venerable and celebrated Capture-the-flag contest, as AI solvers flooded the early scoreboards and leaderboards in an unprecedented fashion. Over 600 players finished this year with 89 of those coming within the first 24 hours. The prize for this year’s contest is a coin! FLARE-On has not had a coin prize since the first contest in 2014. These prizes were available to the first finishers while supplies lasted.
