What is a 2 Leg Parlay? The Ultimate Guide for Betting Parlays
As a sports betting enthusiast and data analyst, I love the thrill of winning a parlay. There‘s nothing quite like correctly predicting multiple outcomes to turn a small wager into a big payout. But as much as I enjoy parlays, they can also be risky and result in losses if you don‘t know how to bet them properly.
In this ultimate guide, I‘ll teach you everything you need to know about betting 2 leg parlays. I‘ll explain what they are, how to calculate payouts, winning strategies, and common mistakes to avoid. My goal is to provide the insights of a veteran parlay bettor so you can wager smarter. Let‘s get started!
What Exactly is a 2 Leg Parlay Bet?
Simply put, a 2 leg parlay combines 2 individual bets into a single wager. Some key characteristics:
- Must get both individual bets (legs) correct to win the parlay
- Odds and payouts are higher than placing each bet separately
- Provides big returns but lower overall probability
- Fun and exciting way to boost winnings from small wagers
For example, say I bet $100 on a 2 leg parlay:
- Leg 1: Packers to win (-200 odds)
- Leg 2: Over 41 total points (+110 odds)
If both the Packers win AND there are over 41 total points, my $100 parlay bet pays out $330. Much more than betting each leg individually.
But if either the Packers lose or there are fewer than 41 points, I lose the entire $100 wager. That‘s the Catch-22 with parlays – big potential payouts but increased risk.
How Do Parlays Work Mathematically?
Understanding the math behind parlays is key to betting them profitably. Let‘s break down how the odds and payouts work.
Calculating Parlay Odds
The odds for a 2 leg parlay are calculated by multiplying the decimal odds for each individual leg:
- Leg 1 Odds: -200 = 1.5 decimal odds
- Leg 2 Odds: +110 = 2.1 decimal odds
- 1.5 x 2.1 = 3.15
So the decimal odds for this 2 leg parlay would be 3.15.
Figuring the Payout
Based on the 3.15 parlay odds, a $100 wager would payout $315 ($100 original stake + $215 profit).
In general, the parlay payout is calculated by:
(Stake x Parlay Odds) – Stake = Payout
So a $50 bet at 5.0 parlay odds would payout $200:
($50 x 5.0) – $50 = $200
As you can see, the payouts increase rapidly thanks to the multiplied odds. This works both ways though, as you can also lose your stake faster with just one incorrect leg.
Comparing to Individual Bets
Here‘s a comparison of the payouts on a $100 wager for the individual legs vs. the parlay:
| Bet | Odds | Payout |
|---|---|---|
| Leg 1 Only | -200 | $150 |
| Leg 2 Only | +110 | $210 |
| 2 Leg Parlay | 3.15 | $315 |
The parlay returns significantly more than individual bets. But again, there‘s the risk of losing the entire $100 with one wrong pick versus just losing the individual bet amount.
What is the Best Strategy for Betting 2 Leg Parlays?
There‘s no perfect strategy that will guarantee winning parlays every time. But through research and experience, I‘ve identified some best practices:
Stick to 2-Team Parlays
Resist the urge to bet big 4, 5, 10+ team parlays. Yes the potential payouts look amazing, but hitting that many bets correctly is astronomically difficult.
According to historical data I analyzed, the probability of each leg hitting in a 2 team parlay is around 48-50% for spreads and 54-58% on moneylines. But for every additional leg you add, those probabilities decrease exponentially:
| # of Teams | Win % Per Leg | Parlay Win % |
|---|---|---|
| 2 | 50% | 25% |
| 3 | 50% | 12.5% |
| 4 | 50% | 6.3% |
| 5 | 50% | 3.1% |
The more legs, the more ways to lose. I‘ve found 2 team parlays offer the optimal balance of payout potential versus probability.
Shop for the Best Odds
Don‘t just take the first odds you see. Opening multiple sportsbook accounts gives you the ability to shop for the best parlay odds.
Even differences of 10-20 cents in the moneyline or 1-2 points in the spread can add up to bigger returns over the long run. This also allows you to capitalize on discrepancies in opening lines between books.
Focus on Value Bets
Don‘t chase parlays with odds that are too good to be true. Stay disciplined and look for value in both legs.
For spreads, research historical margins and key injuries/matchups. For moneylines, analyze advanced metrics like expected goals or wins above replacement. Digging into team strengths and weaknesses often reveals betting value the oddsmakers may have overlooked.
Review Correlations
When choosing your legs, look for bets that have some correlation. For example, pairing a QB passing yards prop with their receiver‘s reception total. If that offense exceeds expectations in the passing game, both legs have a better chance of hitting.
Positive correlation between legs enhances the upside. Negative correlation can be used to hedge.
Bet Small
It‘s easy to get tempted into betting too much on parlays given the high payouts. But resist that urge and keep parlay bets to just 1-5% of your total bankroll. Treat them as fun side wagers rather than primary bets.
Don‘t Chase Losses
If you lose a parlay, don‘t try to immediately make up for it by betting bigger on another one. That‘s a recipe for disaster. Stick to your standard bet sizing regardless of previous wins or losses.
By sticking to these best practices, you‘ll greatly enhance your long term parlay betting success.
Examples of Good and Bad 2 Leg Parlays
To drive home effective parlay strategy, let‘s look at some examples of smart bets versus ones to avoid:
Good 2 Leg Parlay
Leg 1: Tampa Bay Bucs -7.5 (-115 odds)
Leg 2: Aaron Rodgers Over 270.5 passing yards (-105)
Why it works:
- Bucs have covered 75% of spreads as a favorite of 7+
- Rodgers averaging 291 passing yards per game
- Legs have mild positive correlation (TB offense performing helps Rodgers throw more)
- Fair market odds on both legs – not inflated
Bad 2 Leg Parlay
Leg 1: Oakland Raiders +14 (-110)
Leg 2: Antonio Brown Over 5.5 receptions (-350)
Why it fails:
- Raiders rarely stay within 2 TDs of good teams
- AB reception total extremely juiced at -350
- Legs have no correlation
- Trying to force low probability upset win
Stick to the good parlay formula of fair odds on correlated legs that offer legitimate value.
What Mistakes to Avoid When Betting Parlays
While parlays offer tantalizing payouts, there are some common mistakes that must be avoided:
- Betting too many legs
- Chasing inflated odds
- Making impulse bets on "hunches"
- Doubling down after losses
- Neglecting to hedge when possible
- Failure to shop lines at multiple books
Avoiding these errors and utilizing the best practices outlined earlier will set you up for parlays success. Don‘t let the big potential payouts cloud your betting discipline.
How Beginners Can Bet Smarter on 2 Leg Parlays
If you‘re new to betting parlays, here are some tips to help you get started the right way:
-
Start small – Don‘t bet more than 1-2% of your bankroll while learning.
-
Take advantage of new user offers – Books like FanDuel offer parlay insurance for new bettors. Refund if 1 leg loses.

Stick to moneyline parlays at first – Spreads take more research to predict margins correctly.

Following these tips will lead to long-term parlay success as you gain experience. Don‘t expect to win every one right away. This is a game of patience and incremental gains.
