Over/under betting—also known as totals betting—is one of the most popular ways to wager at licensed Colorado sportsbooks. Our guide breaks down how totals work, how payouts are calculated, and how to read the numbers using examples from the Broncos, Nuggets, Rockies, Avalanche, and Buffaloes.
Over/under betting is fully legal for anyone 21+ and regulated by the Colorado Division of Gaming, making it a core part of the Colorado sports betting landscape.
What Is Over/Under Betting?
If you’ve ever wondered what does over under mean in sports betting, the concept is simple: sportsbooks set a projected total for a game, and bettors choose whether the combined score of both teams will finish over or under that number.
This type of wager is also known as totals bet, and the terms are completely interchangeable.
The over/under meaning has nothing to do with which team wins. The outcome only matters in terms of total points, runs, or goals—making it one of the most straightforward options for beginners.
Oddsmakers create these totals using statistical models, matchup analysis, injuries, pace, and historical scoring trends. At Colorado sportsbooks, over/under lines are available for nearly every sport.
Learning how to bet over/under is simple: you’re predicting whether the final combined score will finish higher or lower than the total posted by the sportsbook.
How Over/Under Totals Work
Over/under totals follow a simple structure: the sportsbook sets a projected number for a game—such as 48.5 points in the NFL, 228.5 points in the NBA, or 11.5 runs in MLB—and you decide whether the combined final score will finish over or under that line.
Choosing the OVER means, you expect a higher combined total than the number posted; choosing the UNDER means you expect a lower one.
Sportsbooks often use half-point totals (e.g., 48.5 or 228.5) to prevent ties. When the total is a whole number and the final score lands exactly on it, the result is a push, and your stake is refunded.
| Scenario | Total Line | Combined Score | Result |
| NFL: Broncos vs. Chiefs turns into a high-scoring game | 48.5 | 51 | OVER wins |
| NBA: Nuggets vs. Suns play a defensive matchup | 228.5 | 219 | UNDER wins |
| MLB: Rockies game at Coors Field lands exactly on the posted number | 11 | 11 | Push — stake refunded |
Over/Under vs. Other Bet Types
Over/under betting differs from other wager types because you’re not picking a winner—only the total combined score. Here’s how totals compare to the other primary bet categories at Colorado sportsbooks:
| Bet Type | What You’re Betting On |
|---|---|
|
Over/Under (Totals) |
Combined score of both teams |
|
Moneyline |
Which team wins outright |
|
Point Spread |
Whether a team covers the margin |
|
Same-Game Parlays |
Multiple bets combined into one wager |
How to Read Over/Under Odds in Colorado
Reading over/under odds is straightforward once you understand how Colorado sportsbooks display totals. Most sportsbooks price both sides of a total at -110, meaning you place $110 to win $100 whether you choose the over or the under. You’ll commonly see something like:
Over 48.5 (-110) / Under 48.5 (-110)
Sometimes, the odds won’t be even. For example:
Over 48.5 (-115) / Under 48.5 (-105)
When one side is priced at -115 and the other at -105, it signals that the sportsbook is adjusting for betting action—either shading the line toward one outcome or attempting to balance the handle.
All licensed Colorado sportsbooks use American odds format, so understanding these pricing differences is essential before placing a totals bet.
Understanding the Vig (Juice) on Totals Bets
The vig, short for “vigorish,” commonly called juice—is the built-in commission a sportsbook charges on every totals wager.
When you see -110 listed next to an over or under, it means you must wager $110 to win $100, with the extra $10 representing the sportsbook’s margin.
This pricing structure helps Colorado sportsbooks maintain profitability no matter which side wins.
Some operators occasionally offer reduced-juice lines, such as -105, which lower the cost of placing a bet and improve long-term value for bettors.
While reduced juice isn’t always available, several Colorado sportsbooks feature these promotions during peak sports seasons.
Calculating Over/Under Payouts
Over/under payouts are based on the odds attached to the total, and most Colorado sportsbooks price both sides at -110.
At these odds, you stake $110 to win $100, but the math scales proportionally with any wager size.
While understanding payouts is useful, remember that all licensed Colorado sportsbook apps automatically calculate potential winnings in your bet slip before you confirm a wager.
Payout Table at Standard -110 Odds:
| Bet Amount | To Win | Total Payout |
|---|---|---|
|
$10 |
$9.09 |
$19.09 |

$25 |

Over/Under Betting by Sport in Colorado
Totals vary widely by sport, and understanding how scoring works in each league can help Colorado bettors make sharper decisions.
Factors like pace, altitude, lineup changes, and venue conditions can dramatically influence scoring—especially for local teams such as the Broncos, Nuggets, Avalanche, Rockies, and Buffaloes.
Below is a breakdown of how over/under betting operates across Colorado’s most popular sports.
NFL Over/Under Betting (Denver Broncos)
NFL betting totals generally fall between 35 and 55 points, depending on offensive efficiency, defensive strength, and matchup dynamics.
For the Denver Broncos, home games introduce unique variables. Playing at Mile High means competing in thin air—an environment that can influence both the passing game and special teams.
Altitude may help deep passes travel farther, but it can also challenge kickers, especially in cold or windy late-season conditions.
Weather is another major factor. December and January games in Denver often come with snow, wind, or freezing temperatures, all of which can push totals under expectations.
Bettors should closely evaluate offensive and defensive rankings, pace of play, injury reports (especially to quarterbacks and key defenders), and real-time weather forecasts before committing to a totals bet.
Colorado Tip: The thin air at elevation doesn’t just affect stamina—it can subtly alter ball flight for both quarterbacks and kickers. Factoring in altitude can give bettors an edge when assessing Broncos totals at home.
NBA Over/Under Betting (Denver Nuggets)
NBA totals typically fall between 210 and 240 points, making basketball one of the highest-scoring sports at Colorado sportsbooks.
Fast-paced teams naturally push totals higher, while slower, defensive-focused squads create tighter numbers. Situational factors also matter: back-to-back games often trend toward the under due to player fatigue and reduced shooting efficiency.
For the Denver Nuggets, pace and offensive efficiency are the core drivers of totals movement.
When Nikola Jokić is facilitating at his usual high level and key shooters are healthy, Nuggets overs can become attractive. Conversely, injuries, rotation changes, or defensive matchups can pull totals lower.
Colorado Tip: The altitude at Ball Arena is a real factor. Opponents often show visible fatigue in second halves, which can impact scoring runs, defensive intensity, and pace.
Bettors who track how visiting teams perform late in Denver games may gain an edge when evaluating NBA betting totals.
MLB Over/Under Betting (Colorado Rockies)
MLB totals typically range from 7 to 12 runs, but Colorado is a completely different environment—literally.
Because of Denver’s thin air, balls travel farther, breaking pitches move less, and home runs spike, which is why totals for Rockies home games at Coors Field are often 1–2 runs higher than the league average.
Pitching matchups remain a major factor, especially when fly-ball pitchers take the mound in Denver. Weather also matters: even a light breeze blowing out to center field at Coors can significantly boost run scoring.
Coors Field Altitude Impact
| Venue | Altitude | Typical Total |
|---|---|---|
|
Coors Field (Rockies) |
~5,200 ft |
10–12+ runs |
|
Average MLB Stadium |
Sea level–1,000 ft |
7–9 runs |
Colorado Tip: Because the Coors effect is widely recognized, savvy bettors look for moments when totals are set too low or when pitching conditions create extra value on the over.
Even so, unders can be valuable in rare situations when elite pitchers and cooler weather combine to suppress offense.
NHL Over/Under Betting (Colorado Avalanche)
NHL totals generally fall between 5 and 7 goals, and goaltender matchups are often the biggest driver of where the number lands.
With the Colorado Avalanche, their high-tempo offense and elite playmakers—especially when Nathan MacKinnon is driving the attack—can push games toward the over, particularly against teams that struggle in transition defense.
However, totals can swing the other way when the Avalanche face more defensive-minded opponents who slow the pace, trap in the neutral zone, or limit high-danger chances. Goalie form on both sides matters too: a hot goaltender can keep a game under even when analytics lean over.
Colorado Tip: Look closely at projected goaltender matchups and opponent pace. Avalanche overs often correlate with fast-skating opponents who are willing to trade chances.
College Football & Basketball Over/Under Betting
College over/under betting can be far more volatile than the pro level, with totals ranging dramatically based on offensive schemes, coaching styles, and mismatches.
Colorado bettors see this firsthand with programs like the Colorado Buffaloes, who—especially under Deion Sanders—generate significant national attention and can swing totals based on tempo and explosive play potential.
Totals are fully legal on all in-state college teams, including the Buffaloes, Colorado State Rams, and Air Force Falcons. However, Colorado law prohibits player prop bets involving Colorado college athletes.
Air Force’s triple-option attack is another unique local factor; its methodical, clock-draining style often produces lower-scoring games, impacting totals differently than CU or CSU matchups.Colorado Compliance Note: You can legally bet on game totals for all Colorado college teams, but player props on in-state college athletes are not allowed.
Factors That Affect Over/Under Lines
Over/under totals aren’t arbitrary—they’re shaped by a blend of analytics, market behavior, and real-world conditions.
Colorado bettors gain an edge by understanding the factors oddsmakers weigh when setting and adjusting totals at licensed sportsbooks.
Team Offensive and Defensive Rankings
Offensive and defensive efficiency metrics are core drivers of totals. High-powered offenses naturally push numbers upward, while elite defenses can force lower-scoring outcomes.
Comparing both teams’ efficiency ratings, red-zone conversion rates, and defensive yards allowed per play gives a clearer picture of where a total should fall.
Weather and Playing Conditions
Weather is one of the biggest variables in totals betting, particularly in outdoor sports like the NFL and MLB. Wind disrupts passing and kicking, rain slows offenses, and snow often trends games toward the under.
Colorado-specific: Winter games at Empower Field at Mile High can be affected by temperature swings and gusty winds, while Coors Field’s unique wind patterns and dry air impact baseball scoring.
Injuries to Key Players
Totals can shift dramatically when impactful players are unavailable. A missing quarterback, point guard, or starting pitcher changes offensive rhythm and scoring potential. Always review injury reports and beat writer updates before placing a totals wager.
Pace of Play and Game Style
Game tempo is essential. Fast-paced teams generate more possessions, leading to increased scoring opportunities and higher totals.
Conversely, teams that slow the game—running the ball often in football or using long possessions in basketball—tend to drive unders.
Understanding how each team prefers to operate can reveal value the market hasn’t fully priced in.
Line Movement and Betting Action
Totals often move based on betting volume and sharp action. For example, if the line shifts from 47.5 to 49, it typically indicates heavy money on the over.
Monitoring line movement helps you determine whether the market is reacting to new information or simply to public betting patterns. Before making a wager, consider why the line moved—and whether value still exists.
Over/Under Betting Strategies for Colorado Bettors
Totals betting rewards preparation and precision. Colorado bettors can gain a measurable edge by analyzing scoring patterns, comparing lines across regulated sportsbooks, and leveraging alternate markets.
These practical strategies help elevate your approach whether you’re betting the Broncos, Nuggets, Rockies, Avalanche, or college programs like CU Boulder and CSU.
Research Historical Scoring Trends
Before placing a totals bet, examine how each team has been scoring recently. Looking at the last 5–10 games provides a clearer picture than season-long averages, especially late in the year when form stabilizes.
Home and away splits also matter—Denver’s altitude can boost or suppress scoring depending on the sport and matchup.
Line Shop Across Colorado Sportsbooks
Totals often differ slightly across operators, and even a half-point difference can decide a win or a push. For example, one Colorado sportsbook might offer 47.5 while another posts 48.
Because margins in totals betting are thin, shopping across licensed operatorscan increase your long-term profitability.
Consider Alternative Totals
Most Colorado sportsbooks offer alternate totals at varied odds. These let you choose lines that offer higher potential payouts or more conservative returns depending on your preference.
Example
- Standard total: 48.5 (–110)
- Alternate total: 52.5 (+180)
Alternate totals are excellent when you have a strong read on game script.
First-Half and Quarterly Totals
You’re not limited to full-game totals. First-half, second-half, and even quarterly totals are available for most NFL, NBA, and NCAA games.
These smaller markets are ideal if you expect a team to start quickly, slow down late, or show predictable pacing tendencies. They can also help avoid late-game variance such as garbage-time scoring.

Responsible Gambling for Over/Under Bettors
Over/under betting can be exciting, especially in high-scoring sports like football and basketball, but it’s important to approach totals wagering with a clear and responsible mindset.
Start by setting a firm budget before placing any bets—decide what you can comfortably afford to wager and stick to it, regardless of wins or losses.
Avoid the temptation to chase losses by immediately betting the next game’s total; emotional decisions often lead to poor outcomes.
Every licensed Colorado sportsbook provides responsible gambling tools such as deposit limits, session time limits, wager limits, and optional cool-off periods you can activate directly in the app.
Remember: over/under betting should enhance your enjoyment of sports, not serve as a financial strategy. Keep your wagering controlled, consistent, and fun. If you have any problems, do not hesitate to check our responsible gambling page.

Over/Under Betting FAQs
What does over/under mean in sports betting?
In over/under sports betting—also called totals betting—you’re wagering on whether the combined score of both teams will finish over or under a projected number set by the sportsbook. It doesn’t matter who wins the game; only the final total determines the outcome.
Does overtime count in over/under bets?
Yes. For most sports, overtime scoring counts toward full-game totals unless the sportsbook specifically lists otherwise. This applies to NFL, NBA, NHL, and college sports. The exception is MLB, which has no overtime but includes all extra innings in totals scoring.
What happens if the total lands exactly on the over/under line?
If the combined score lands exactly on a whole-number total—such as 48 instead of 48.5—the result is a push. In that case, the sportsbook refunds your stake in full. Half-point lines (like 48.5) are designed to eliminate pushes.
Can I bet over/under on Colorado college teams?
Yes. Colorado allows over/under betting on in-state college teams like the Colorado Buffaloes and Colorado State Rams. However, player prop bets on Colorado college athletes are prohibited under state law. Totals wagers remain fully legal.
What is the vig on over/under bets?
The vig—short for “vigorish”—is the sportsbook’s built-in commission. For totals betting, the standard vig is -110, meaning you wager $110 to win $100. Some Colorado sportsbooks occasionally offer reduced-juice lines (e.g., -105) on select games.
What’s a good over/under betting strategy?
Effective totals betting starts with research. Analyze scoring trends, pace of play, weather conditions, injuries, and venue factors like altitude. Line shopping across Colorado sportsbooks is also key—half-point differences can impact long-term results.
Are over/under bets available for live betting?
Yes. All major Colorado sportsbooks offer live over/under betting, where totals adjust in real time as the game unfolds. Fast-paced sports such as NBA and NFL provide especially active in-play totals markets. Live betting requires quick decisions, so stay focused on game flow and momentum.
