Ly's Challenges is a subset of the mini-games in Rayman Revolution, which are offered to Rayman by Ly the Fairy, if he visits her in one of the three locations - Ly's House in The Minisaurus Plain, Ly's Stele in Globox's House or Ly's Cave in Rainbow Creek.
Each of the challenges requires Rayman to collect a certain number of Red Lums, competing against time, obstacles or enemies. Collecting all the lums constitutes a completion of that challenge, and Ly will award Rayman by permanently extending his life bar. Contrary to normal levels, all lums must be collected in a single playthrough - failing to complete the course, or completing it without all the lums will require Rayman to start over from 0 lums.
