The new 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.

This is a free bracket pick'em pool based on the March Mammal Madness Tournament. Instead of a pool for sporting events, this pool is based on mammal vs mammal combats. Actually it has grown to include any species vs any species, not just mammals. Pick who will win each bout.

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 2025 MMM tournament at the official March Mammal Madness website!

Unlike our other pools, there are no changeable league options. Players pick the whole bracket before the first bout starts. The scoring is the same for all players and is exactly the same as the official March Mammal Madness Tournament rules.
