The MMMMM is a free award-winning monthly crossword, published at noon on the first Tuesday of each month. Its difficulty level is similar to a NY Times Wednesday or Thursday puzzle. To finish the puzzle, solvers need to figure out the meta, which is usually a song or band. Solvers have until Sunday at 11pm to submit their answer to the meta.
In addition to these metas, the 12 monthly puzzles include a mega-meta. The 13th and final puzzle of the year is published on the last Tuesday of December, and gives hints for the mega-meta. Solvers can guess the mega-meta early and earn bonus points as explained in the contest rules.
Each month, a randomly chosen solver gets a free MMMM coffee mug. At the end of the year, a Grand Prize winner is chosen using a random drawing. All solvers who that have solved at least 9 of the 13 metas correctly are eligible to win the Grand Prize.
