March Madness 2025 tournament format and schedule
The event, culminating in the March Madness National Championship, is a single-elimination or “knockout” tournament. Once a team loses — it’s out.
Each winner will play another in the next round, and so on until the tournament’s champion is crowned. Selection, seeding, and region allocation take place on the Sunday before the tournament, dubbed Selection Sunday.
The tournament is played over three weekends, but the action kicks off with the First Four.
- First Four — Four games played between the four lowest-seeded automatic qualifiers and at-large teams within their subset. The former compete for the #16 seed line, and the latter for a line in the #11–14 range, which varies each year.
- 1st weekend — First and second rounds are played.
- 2nd weekend — Regional semifinals (Sweet 16) and finals (Elite Eight).
- 3rd weekend — The regional winners advance to the national semifinals and finals (Final Four).
- National Championship — The two remaining teams lock horns in the tournament’s rip-roaring finale at State Farm Stadium in Glendale, Arizona.
Here’s the round breakdown, number of games played, and key dates to watch out for:
| ⛹️ Round | 🏀 Number of games* | 📅 Men’s division | 📅 Women’s division |
|---|---|---|---|
| First Four | 4 | March 18–19 | March 19–20 |
| First round | 32 | March 20–21 | March 21–22 |
| Second round | 16 | March 22–23 | March 23–24 |
| Sweet 16 | 8 | March 27–28 | March 28–29 |
| Elite Eight | 5 | March 29–30 | March 30–31 |
| Final Four | 2 | April 5 | April 4 |
| National Championship | 1 | April 7 | April 6 |
*All scheduled games account for one rest day between each game.
March Madness brackets explained
“Brackets” refer to the tournament’s structure, organizing teams into a predetermined sequence of matchups.
When you fill brackets and bet on teams within, you’re betting on the winners of each game — from the opening rounds to the National Championship.
March Madness brackets are an integral part of the tournament, and can be a huge factor in who makes it to the Final Four. The brackets for the men’s and women’s teams are set on Selection Sunday.
Selection
There are 68 teams in both divisions, of which 32 spots are automatically given to teams that won their conference’s championship. The remaining 36 slots are at-large bids awarded by the Selection Committee. Major conferences are generally favored over mid-majors with similar performance.
These teams are then split into four regions of 16 teams each: East, Midwest, South, and West. Unlike conferences, the regions are not tied to the team’s geographical location; instead, the Selection Committee determines which team plays for which region.
Seeding
Seeding runs in tandem with selection. The S-curve (overall seed ranking #1–68, also referred to as the “true seed”) is set by the Selection Committee, based on factors like record, strength of schedule, as well as the NCAA Evaluation Tool (NET) in men’s Division I tournament and the Rating Percentage Index (RPI) in all other championships.
Each region’s teams are then assigned a seed from #1–16. The S-curve is used to keep each region balanced, ensuring that the top four seeds in each region are comparable in strength to the top four in every other region. The #1 seed, for example, can’t be paired with the strongest #2 seed (#5 overall).
Popular March Madness bets
Sportsbooks add an extra layer of strategy to March Madness betting on top-of-bracket moneylines by offering point spreads and same-game parlays, alongside various performance, team, and player props.
Here are common and popular March Madness markets to watch out for:
Spreads
Point spreads, or bets on the gap in points between two teams, are standard in basketball betting but gain an extra boost of popularity during March Madness. The NCAAB tournament lends itself to lucrative point spreads during the opening rounds, as higher-ranked teams go up against lower-ranked opponents.
Props
Big leagues tend to have wild bets, and March Madness is no different. The NCAAB March Madness league is perfect for performance and team propositions, such as race to X points, three-way margins, odd/even totals, whether the game will end with a buzzer beater, and other unique markets.
Futures
Futures are available ahead of the March Madness tournament to let you try and predict the outright winner in advance. Some sportsbooks offer futures for the tournament’s MVP, a.k.a. the Final Four’s Most Outstanding Player, and other player markets.
Derivatives
Derivatives let you predict outcomes of specific segments of March Madness games: both 20-minute halves and overtime. A great option for punters familiar with the teams’ performance and pace on game day.March Madness betting strategies and tips
Betting on March Madness doesn’t differ significantly from wagering on any other sporting event. While familiarizing yourself with March Madness bet types can go a long way, there are a few other tips and strategies to consider before you fill that bet slip.
Look for experience and balance
You tend to see the same teams and coaches advance to the final rounds, and for a good reason. This doesn’t mean an underdog story can’t happen, but teams with history of good lineup management and sound adjustment from game to game are generally a safer bet. Evaluate offensive and defensive efficiency ranks — you’re looking for strong offense and stalwart defense.
Evaluate the strength of the schedule
Strength of schedule refers to the difficulty of a team’s schedule based on the opponent’s win percentage. This shows team performance, but make note of which conferences were competitive and which were two-dimensional. A low-loss record in mid-majors, for example, falls short of a big-league team’s higher loss count when consistently facing tougher matchups.
Factor in recent form and momentum
Pay attention to every school’s recent form and momentum. Teams with a good track record in their conference tournaments are solid considerations for early progression. Don’t overlook consistent performance; the win-loss ratio isn’t the be-all and end-all.
Take advantage of in-play betting
Consider hedging your pregame wagers with live betting. In-play March Madness betting lines generally move with every play and possession, offering opportunities to take advantage of lucrative odds and put your real-time spectator edge into play.
Account for the home-court edge
Teams may end up on the opposite coast or merely miles away from court for March Madness. Factoring in travel wear (and crowd noise) can be a deciding factor early on in the tournament, when you can make the most of point spreads. Analyze home/away splits, cover, wins/losses, field-goal percentage, and points allowed to see which teams are less likely to flop when on the road.
Go for teams that cover the spread
In the latter March Madness brackets, look for high-ranking teams with strong Against The Spread (ATS) records. The majority of March Madness champions over the last 15 years covered >55% of the games in their championship seasons, indicating reliable performance and exceeded expectations. A good ATS record isn’t a compass pointing to the winner, but is wise to reference.
Keep tabs on powerhouse schools
The Power Five conferences are part of the nation’s most elite conferences in the tier, and the stepping stone to some of the sport’s most successful athletes. Keep an eye on powerhouse-school teams stepping up their game for March Madness, as many top performers tend to peak in postseason.
Stay informed
Knowledge is power, so arm yourself with hard data and keep abreast of latest news. A close eye on news sources will lend insights into team strategy, latest standings, betting odds, expert analysis, player injuries, and even betting favorites for March Madness.
Expert tip: gamble responsibly
Just because March Madness is big event doesn’t mean you should go as wild as the crowd. No matter the strategy or tip at your disposal — winning a bet is never guaranteed. Place limits on deposits, wagers, and time to keep reality in check and problem behavior at bay.
If you’re experiencing gambling-related harm, contact national helplines or a support organization in your state.
