About Puzzle Marathon

This is a differently designed LMI test.
  • All puzzle grids in this test are marathon grids, i.e. they are much bigger in size than usual.
  • There is no fixed time limit for any puzzle. The challenge for solvers is to solve all of them in least amount of time.
  • The test will be open slightly for more than a week, with the idea that everyone can get around to solve all puzzles conveniently.
  • Each puzzle can be started, solved and submitted independent of others, and in any order, anytime during the week.

Thanks to all authors for writing puzzles for Marathon.
