Every March, millions of Americans fill out their brackets with dreams of outsmarting friends, family, and coworkers. Yet most end up frustrated when their carefully crafted March Madness bracket predictions fall apart before the first weekend ends.
What separates the top finishers from everyone else? It's not luck — it's strategy.
Casual fans might focus on which teams are "hot" or who has the best guards, but savvy bracket pickers know that winning comes down to the math behind pool success.
Here's the good news: You don't need to be a statistics professor to dramatically improve your chances. Instead, follow these five research-backed secrets that can triple (or even quadruple) your odds of winning your pool.

Tip 1: Understand Your Scoring System
Most bracket pickers make the same fundamental mistake: they create the same bracket regardless of their pool's scoring rules. This is like a basketball team running the same offense regardless of the defense they're facing.
Different scoring systems can completely change your pool strategy:
In traditional scoring (1-2-4-8-16-32), where points double each round, the later rounds are more critical. Consider this: Picking all 32 games correctly in the first round (nearly impossible) nets you 32 points. Getting your champion pick right is also worth 32 points.
Amazingly, even if you have a perfect first round and someone else gets only 16 of 32 correct but picks the right champion, they'll finish with more points than you if your champion pick fails.
In flatter scoring systems (like 1-2-3-4-5-6), earlier rounds carry much more weight. In these pools, correctly predicting first-round upsets becomes significantly more valuable.
For upset bonus systems, where you get extra points for correctly picking lower seeds to win, optimal strategy often calls for bold upset picks that look ridiculous in standard pools. One successful double-digit seed advancing deep can compensate for missing several other picks.
Tip 2: Pool Size Determines Your Risk Level
The number of competitors in your pool should influence how much risk you take with your picks:
In small pools (under 25 entries):
Being too aggressive with upset picks is often the silent killer of brackets
Conservative strategies frequently prevail (even if they are boring)
Find a few key value picks while otherwise sticking with favorites
In medium pools (25-100 entries):
Balance conservative and aggressive picking
Look for 1-2 contrarian picks in later rounds
Avoid the most popular champion picks if (and only if) reasonable alternatives exist
In large pools (100+ entries):
Aggressive strategies become necessary
You'll need to differentiate your bracket significantly
Making bold but calculated picks on undervalued teams is essential
Think of it this way: In a 10-person pool, you need to be better than nine other entries. In a 100-person pool, you need to be better than 99. Playing it safe is a losing strategy in the latter since someone in a large pool will get lucky with a few upset picks.
Identifying a reasonably strong—but undervalued—title contender in large pools can be the difference-maker. When Connecticut won as a No. 4 seed in 2023, they were shockingly unpopular in bracket pools despite having excellent metrics in many predictive systems.

Tip 3: Find Value in Public Pick Rates
Every year, millions of brackets create patterns in how teams are selected. These patterns reveal opportunities where the public is either over-picking or under-picking certain teams relative to their actual chances.
For example, in 2019, Virginia was significantly undervalued in bracket pools after becoming the first #1 seed to lose to a #16 seed the previous year. Public perception avoided them, but their underlying metrics remained elite, creating a perfect value opportunity. Virginia went on to win the national championship.
Similarly, traditionally successful programs like Duke, Kentucky, and North Carolina are often over-picked relative to their actual odds of advancing. At the same time, less glamorous schools with strong metrics can be overlooked.
The key is finding the sweet spot: teams with a legitimate chance to advance far but aren't being selected in too many brackets. That's how you score points your opponents miss—the only way to move up the standings.
Bonus Tip: Where to Get Public Pick Data
Most bracket players don’t have access to reliable public pick data. PoolGenius tracks public pick rates from multiple sources to identify exactly which teams are overvalued or undervalued—then tells you which opportunities are worth taking in your specific pool.

Tip 4: Avoid Bad Bracket Advice
Every March, college basketball analysts share their favorite bracket-picking "rules of thumb." Most of these so-called rules are not only unhelpful but actively harmful to your chances of winning.
Examples of destructive bracket myths include:
"Always pick at least one 12-seed to beat a 5-seed."
"Your Final Four shouldn’t have more than two #1 seeds.”
"Don't pick a team that lost early in their conference tournament."
"Make sure your Final Four seeds add up to a certain number."
Every NCAA tournament is different. The most accurate March Madness bracket predictions come from evaluating the specific teams and matchups in the current year's tournament—not from forcing your picks to match historical patterns.
That doesn't mean historical data isn't valuable. However, it shouldn’t be used to create simplistic rules based on seed numbers (and other subjective factors) alone.
Tip 5: Use Objective Data, Not Emotion
Perhaps the most important bracket-picking principle is to trust objective data over subjective impressions.
Many bracket pickers make selections based on the handful of games they watched during the college basketball season, comments from TV analysts, or team reputations. This approach introduces significant bias into your March Madness bracket predictions.
The most reliable bracket forecasts come from:
- Computer rating systems that evaluate all 5,000+ games played during the season
- Betting markets that incorporate the collective wisdom of sharp oddsmakers
- Efficiency metrics that measure how teams perform on a per-possession basis
- Injury adjustments accounting for players who missed significant time
The challenge is synthesizing all this information into an optimal bracket strategy. Even if you identify teams that are more likely to advance than others believe, you still need to determine how these insights should affect your specific pool.
That’s where PoolGenius comes in.
