Need some last minute help with your bracket before March Madness tips off? Check out the University of Illinois at Urbana-Champaign’s (UIUC) Bracketodds, which uses probability theory and statistics to predict and analyze the success of teams in the NCAA Men’s Basketball Tournament based on seeding.

The website was created in 2011 as an educational project with undergraduate computer science students at UIUC and is intended to be used as “a tool to evaluate and compare various seed combinations in later rounds of your bracket and to assess your bracket odds” as the model does not have the accuracy to give probabilities for games before the Sweet Sixteen.

If you’re struggling to complete your bracket, the bracket generator can build a bracket for you by sampling across the 9,223,372,036,854,775,808 possible brackets. However, it is important to note that the generator is blind to the teams themselves and only makes predictions based on seed matchups.

Rather unsurprisingly, higher seeds have better odds of winning the championship than do lower seeds, but the greatest thrill of March Madness is found in the upsets and deep runs by lower seeds.
