How the predictor works
The bracket above was filled game by game. For each game the predictor looks up how often a team with that seed has beaten a team with the other seed, then rolls for the result in the style you chose. The winner moves on and meets the next winner, all the way to the championship. It is the same reasoning most bracket players use, done in one tap.
It knows seeds, not teams. A 12 seed that is better than its seed suggests, or a 1 seed with an injured star, is something only you can judge, so treat the prediction as a starting point and change the games you have an opinion on.
First-round odds by seed
These are the rounded win rates the predictor uses for the First Round, from the men's tournament since 1985:
| Matchup | Better seed wins | Upset |
|---|---|---|
| 1 vs 16 | 99% | 1% |
| 2 vs 15 | 93% | 7% |
| 3 vs 14 | 85% | 15% |
| 4 vs 13 | 79% | 21% |
| 5 vs 12 | 64% | 36% |
| 6 vs 11 | 61% | 39% |
| 7 vs 10 | 61% | 39% |
| 8 vs 9 | 50% | 50% |
Only two 16 seeds have ever won a men's game (UMBC in 2018 and Fairleigh Dickinson in 2023), while the 8 vs 9 game is close to a coin flip. The 5 vs 12 game is the most famous upset slot: the 12 seed wins about a third of the time.
Which style should I pick?
| Style | What it does | Good for |
|---|---|---|
| Safe | The likelier winner every game | Small pools, or a baseline to compare against |
| Balanced | Upsets at about half their historical rate | Most office pools |
| Bold | Every game at its full historical odds | Big pools, where you need to stand out to win |
Most pools score each round the same total (1, 2, 4, 8, 16 and 32 points per correct pick), so the champion is worth as much as the whole First Round. Spend your upsets early and keep strong teams in the Final Four.

Frequently asked questions
How does the predictor pick winners?
Every game is decided from how often that seed has won in the past. First-round odds come from the men's tournament since 1985; later rounds use a curve fitted to the seed gap, so a 1 seed is a big favourite over an 8 seed but close to even against a 2. It does not look at team stats, injuries or schedules.
What is the difference between Safe, Balanced and Bold?
Safe always takes the likelier winner, so the four 1 seeds reach the Final Four. Balanced rolls for upsets at about half their historical rate. Bold rolls every game at its full historical odds, so it picks about as many upsets as a real tournament has.
Why do I get a different bracket each time?
Each press of Predict a new bracket rolls the dice again, the way the real tournament would. Keep the one you like, change any game by tapping it, then press Share link to save it.
Can I use it with the real teams?
Yes. After Selection Sunday on March 14, 2027, open Enter the teams and region names and paste the field. The predictor keeps working by seed and shows the team names on every line.
How many upsets should a bracket have?
A typical men's tournament has around a dozen games won by the worse seed, most of them in the first two rounds. Picking every favourite rarely wins a big pool; picking too many upsets rarely survives the first weekend. Balanced is a good start for an office pool.
Is there an AI version?
