The March Mammal Madness Busted Bracketeers pool is an abbreviated version of the March Mammal Madness pool. It works just like the March Mammal Madness pool except it begins with the Sweet Sixteen. If your initial MMM bracket picks didn’t quite pan out, this pool allows you to start anew, picking a new champion and following the action through to the end.

Players pick the whole bracket before the first match starts. The scoring is the same for all players and is exactly the same as the official March Mammal Madness Tournament rules.

March Mammal Madness is a simulated tournament where a team of scientists research the combatants and their habitats to determine the winners. Find out everything about the MMM tournament at the official March Mammal Madness website!

Starting in 2026, the March Mammal Madness Pools are exclusively available on poolsmmm.org, which has all the same great features as poolsbyround.
