How to Fill Out a March Madness Bracket
Step 1. Download a Blank Bracket
The first step is getting a blank bracket once the tournament field is announced. The NCAA selection committee reveals the 68-team field on Selection Sunday, which typically occurs in mid-March. Blank brackets are available from NCAA.com, sports media sites, and sportsbook apps.
Step 2. Understand the 68-Team Structure
The NCAA tournament follows a single-elimination format with the following rounds: First Four (8 teams compete for the final 4 spots), Round of 64 (32 games), Round of 32 (16 games), Sweet 16 (regional competition), Elite Eight (regional champions determined), Final Four (national semifinals), and the National Championship (final game). You must predict the winner of all 63 games to complete your bracket.
Step 3. Learn the Seeding System
Historical win percentages by seed matchup reveal where upsets are most likely. The 12-over-5 upset is the classic upset spot at roughly 35.7%, while the 8-vs-9 matchup is essentially a coin flip at 48.6%. See the upset trends table below for full details.
Step 4. Predict Winners, Balance Picks, and Submit
Start with your Final Four picks and work backward. Include calculated upsets for differentiation while keeping some top seeds advancing deep into the tournament. Your bracket must be submitted before the first Round of 64 game, usually around noon ET on Thursday.

Bracket Strategy and Scoring Systems
Standard Doubling (Most Common)
| Round | Points per Correct Pick |
|---|---|
|
Round of 64 |
1 point |
|
Round of 32 |
2 points |
|
Sweet 16 |
4 points |
|
Elite Eight |
8 points |
|
Final Four |
16 points |
|
Championship |
32 points |
The maximum possible score under standard doubling is 192 points. Alternative scoring formats include Fibonacci (1-1-2-3-5-8), flat scoring (equal points per round), and upset bonus systems that award extra points for correctly picking lower seeds.
Pool Size Strategy
Small pools (under 20 entries): Play conservatively with favorites. In smaller fields, consistency matters more than differentiation.
Large pools (100+ entries): Make contrarian picks for leverage. Analyze ownership percentages to differentiate your bracket from the majority.

March Madness Upset Trends
The Classic 12-Over-5 Upset
Since the tournament expanded to 64 teams in 1985, at least 1 12-seed has defeated a 5-seed in 33 of the last 39 tournaments. That’s an occurrence rate of roughly 85%, making the 12-over-5 upset the single most reliable bracket pick available.
Famous Cinderella Runs
- Loyola Chicago (2018): 11-seed reached the Final Four
- Oral Roberts (2021): 15-seed reached the Sweet 16
- Saint Peter’s (2022): 15-seed reached the Elite Eight
Lower-seeded teams are well-rested and higher seeds have had little time to prepare for unfamiliar opponents. Later rounds tend to feature fewer surprises as stronger teams advance.
-
Always include at least 1 12-over-5 upset in your bracket. This matchup produces an upset in roughly 85% of tournaments.

Additional markets include conference performance props, individual game spreads, moneylines, totals, same-game parlays, and live in-game betting.
According to data from the American Gaming Association (AGA), legal sports betting handle during March Madness reached an estimated $3.1 billion in 2024. This reflects the tournament’s position as 1 of the most heavily wagered events in American sports.
March Madness Betting Odds
Championship odds vary across sportsbooks. Shopping for the best line can improve potential returns.
| Sportsbook | Favorite | Second | Third |
|---|---|---|---|
| FanDuel | +340 | +340 | +480 |
| BetMGM | +320 | +325 | +475 |
| DraftKings | +320 | +340 | +450 |
| bet365 | +325 | +340 | +475 |
| Caesars | +315 | +315 | +425 |
Understanding American odds: Odds of +400 mean a $100 bet could return $400 in profit if the team wins. Odds of -150 mean you would need to bet $150 to potentially win $100 in profit.
Since the tournament expanded to 64 teams in 1985, No. 1 seeds have won roughly 65% of national championships. The betting favorite entering the tournament has won roughly 1 quarter to 1 third of the time.

Types of March Madness Bets
Point Spread Bets
Spreads balance games between favorites and underdogs by assigning a handicap to the stronger team. For example, a No. 1 seed at -20.5 means they must win by 21 or more points for the bet to pay out.
Moneyline Bets
Bettors only need their chosen team to win the game, without covering a spread. This is the simplest bet type available.
Totals (Over/Under)
Sportsbooks set a projected total score, and bettors wager on whether the actual combined score will finish above or below that number.
Futures Bets
Futures allow bettors to wager on outcomes determined later in the tournament, such as the national champion or Final Four participants.
Player Props
Player props focus on individual statistics such as points scored, rebounds, assists, and three-pointers made in a single game.
Same-Game Parlay (SGP)
SGPs allow bettors to combine multiple outcomes within the same matchup into a single wager for larger potential payouts. See our Same-Game Parlay Guide for detailed strategies.
Live Betting
Live betting allows wagers to be placed during a game as odds change in real time. This is particularly popular during the opening weekend of March Madness. See our Live Betting Guide for more details.
Parlays and Round Robin
Parlays require every selection to win but offer larger payouts than individual bets. Use our Parlay Calculator to estimate potential payouts.
