What is a parlay? In sports betting, a parlay, accumulator, multi-bet, and combo bet are different names for the same thing. Sportsbooks use different terms, but they all describe one of the most popular bet types in Canada.

It offers bigger potential payouts than a regular bet. A small stake can turn into a much larger return, but winning one is harder than it looks.

In this article, we’ll explain what parlays are, why Canadian bettors use them so much, and how to place one on TonyBet. Keep a calculator close, because we’ll be dealing with a lot of numbers.

What’s a Parlay Bet?

A parlay bet is one where you combine two or more selections into one bet slip for a chance at a higher payout than betting on singles.

Let’s assume your favourite Toronto teams are playing over the weekend and you decide to bet a total of C$100. On TonyBet, three lines catch your eye:

TonyBet gives you the option to place these as three single bets or combine them into a parlay. Let’s see how each option works.

You decide to place single bets with the following stakes:

Your total return in this scenario would be C$191.10. As you are staking C$100 in total, your profit will be C$91.10.

Now, let’s look at the same selections as a parlay. The odds for each selection multiply together (2.10 x 1.91 x 1.77 = 7.10). That means your combined odds will be 7.10. A C$100 stake on this parlay will return C$710 (7.10 x 100). Your profit: C$610.

Without a second thought, the parlay looks like the better option. C$610 in profit is much more attractive than C$91.10. But there’s a catch. Every selection has to win. If the Maple Leafs win and the total in the Raptors’ game lands over 225.5, but the Blue Jays fail to cover +1.5, the entire parlay loses, and your full C$100 stake is gone.

With single bets, one losing pick does not automatically ruin the whole weekend. Even if the Blue Jays fail to cover +1.5, the winning Maple Leafs and Raptors bets still return C$120.30, leaving you with a C$20.30 profit instead of losing the full C$100.

That’s what a parlay bet is: higher risk and much higher payout.

How Parlay Betting Works

The word parlay has Italian and French origins, from the word paroli, meaning to roll your winnings into another bet. That’s exactly what a parlay does: you take one bet and stack it on another.

But the math here is important. With single bets, you add the return from each wager. With a parlay, you multiply the odds. Every selection becomes tied to the next one.

Think of it like a deck of cards versus a card pyramid. With single bets, the cards are stacked flat. Remove one, and the rest remain. With a parlay, every card depends on the next. Pull one out, and the whole pyramid falls.

There are a few things to decide when placing parlay bets. Let’s break them down.

Number of Selections

Every parlay starts with at least two picks. The smallest option is a two-leg parlay, while TonyBet allows up to 20 selections on a standard parlay slip.

TonyBet also has a Combo Booster promotion. If you place three or more selections, each with odds of 1.20 or higher, the sportsbook boosts your final combined odds.

With three selections, the combined odds increase by 5%. With 20 selections, the boost reaches 100%, which means TonyBet doubles your final odds. There are no wagering requirements attached to the boosted odds. Any winnings are yours to withdraw.

Odds Multiplication

As you add legs to your parlay, the odds change.

Continuing with our example: if your parlay includes only two selections, the Toronto Maple Leafs (2.10) and the Toronto Raptors (1.91), your combined odds will be 2.10 x 1.91 = 4.01.

Add another leg, the Toronto Blue Jays at 1.77, and your odds jump to 7.10. Every extra selection increases the combined odds.

When you are placing a parlay on live events, you have to be extra careful. Any change in odds on one selection will automatically change your combined odds too. A selection can also become void if a game is interrupted or abandoned, or if, in the case of props, a player does not play. In that case, the leg is removed, and the remaining odds are recalculated.

For example, if the Toronto Raptors market is cancelled after you place the bet, the parlay stays alive with the Maple Leafs and Blue Jays selections only.

What Happens if One Leg Loses

One losing pick kills the parlay slip. Since every selection is tied together and multiplied to create the final odds, one loss causes the entire bet to lose.

That’s the catch with parlay bets. Every extra selection adds another chance for the bet slip to fail. A two-leg parlay is easier to win than a five-leg parlay because fewer things can go wrong.

Parlay Bonuses

One reason parlays are so popular among Canadian bettors is that many sportsbook promotions are built around them. Many online sportsbooks in Canada limit welcome bonuses, reloads, and free bet offers to accumulator bets. If you want to use those offers, you need to place a parlay.

TonyBet is different. The sportsbook allows promotions to be used on both single bets and parlays. There is still a minimum odds requirement and wagering condition, which changes from one offer to another, but you are not forced into a parlay just to activate an offer.

TonyBet also marks some selections with a “Boosted” tag. If you add one of those picks to your bet slip, the sportsbook gives you the option to create a parlay with the Combo Booster promotion attached.

Types of Parlay Bets

You can build a parlay in different ways. You can combine picks from different games in the same sport, several selections from the same match, or picks from different games across different sports.

Types of Parlay Bets

Standard Parlays

A standard parlay combines selections from separate matches within the same sport. You can place moneyline bets across all selections or mix them with totals and handicaps.

Example:

This is the most common way to bet a parlay.

Same-Game Parlays

A same-game parlay (SGP) uses multiple picks from a single match. For example, in the next MLS game featuring Toronto FC, you could combine:

That creates one parlay from that match. Soccer is especially popular among Canadian bettors for this style of betting because you can combine match result, total goals, both teams to score (BTTS), cards, corners, and player props in one slip.

The same approach also works in the NBA and NFL, where bettors can combine total points, player props, handicaps, and team totals.

On TonyBet, you can build SGPs using Bet Builder. It lets you customise your picks from one match into a single bet slip and see how the odds change before you place the bet.

Cross-Sport Parlays

Cross-sport parlays combine picks from different leagues and sports, like the first example we used:

A lot of Canadian bettors build this type of bet slip on weekends when the NHL, NBA, NFL, and soccer are all on the board. You can build cross-sport parlays with almost any market type: moneylines, handicaps, totals, player props, team totals, or a mix of all of them in the same slip.

How to Bet a Parlay on TonyBet

With TonyBet’s one-tap bet feature, placing a parlay is simple:

  1. Log in or sign up on TonyBet.
  2. Open the sportsbook section and choose either pre-match or live betting.
  3. Browse the featured picks or choose the sport you want to bet on.
  4. Select a match and choose your market: moneyline, total, handicap, and/or player prop.
  5. As you add selections, TonyBet automatically calculates the combined odds.
  6. Enter your stake and review the potential return.
  7. Confirm the bet.

The bet slip does all the math for you. If your selections combine to 6.48 odds and you stake C$15, TonyBet immediately shows a possible return of C$97.20.

Some events also include a Cash Out feature. If your first two picks win and the final game has not started yet, you may have the option to settle the ticket early and lock in part of the profit.

Main Advantage of Parlay Betting

The biggest reason people like parlays is the payout. A single C$10 bet at 1.80 odds will return C$18. But combine three selections at 1.80 each into one parlay, and the same C$10 stake will return C$58.32.

Parlays also give you more action to follow. If you have the Toronto Raptors, Toronto Maple Leafs, and Toronto Blue Jays on the same ticket, you have action all evening. That’s one reason parlay betting is so popular during busy sports weekends in Canada.

Another advantage is for bettors with smaller bankrolls. Someone betting C$5 or C$10 can still chase a larger payout without putting too much money at risk.

Risks of Parlay Bets

Right off the bat, parlays are hard to win. Every additional selection increases the payout but reduces the chance of winning. For a parlay to cash, every leg has to win.

Probability is the real problem because the chances multiply along with the odds. For example, a four-leg parlay with every selection priced at 1.80 creates combined odds of 10.50 — 1.8 ^ 4 = 10.4976 ≈ 10.50.

But if each leg has roughly a 55.56% chance of winning, the chance of all four picks winning is only about 9.5% — P = (1/1.8) ^ 4 = (0.5556) ^ 4 ≈ 0.095 ≈ 9.5%.

The payout looks great, but the odds of actually landing it are much lower than most bettors expect.

Another risk is getting greedy. A lot of bettors start with two strong picks, then keep adding more because the payout keeps getting bigger. One late touchdown, one empty-net goal, or one missed free throw can ruin the ticket.

Smart Tips for Building Better Parlays

The best parlays are not the ones with the biggest possible payout. They are the ones built around strong picks, realistic odds, and a balance between risk and reward.

Here are some smart tips to help you build winning parlays.

Smart Tips for Building Better Parlays

Keep It Simple

Bettors who win parlays keep their tickets simple. Two- and three-leg parlays land far more often than six- or seven-leg tickets. A same-game parlay built around the Edmonton Oilers to win and Connor McDavid over 1.5 points has a much better chance than a six-leg ticket built from random games.

Research Is Key

If you want more consistent parlay wins, make research your best friend.

Also remember:

For example, a starting pitcher can completely change how strong a baseball team is on a given day. Kevin Gausman has been one of the best starters for the Toronto Blue Jays, and when he pitches, the team are more likely to win. If you see a game without him on the mound, the same bet on the Blue Jays may play out very differently.

Value vs Probability

You may see three likely-to-win picks at 1.20 odds each and feel you should build a parlay. But together, those selections create odds of only 1.73 — 1.20 ^ 3 = 1.728 ≈ 1.73

Now calculate it yourself. If you split a total of C$10 across three separate singles, your total return would be about C$12. If you place the full C$10 on the parlay, the return rises to C$17.28. The extra payout is only C$5.28, but if just one selection loses, you lose the entire C$10.

Build parlays by matching value against your stake and the probability of winning.

Avoid Adding Longshots Just to Boost the Odds

Bettors sometimes add random longshots from different games just because they make the payout look bigger.

A bettor might start with the Toronto Maple Leafs to win and the Toronto Blue Jays +1.5, then add an anytime goalscorer bet at 5.00 odds from another NHL game. The payout jumps, but the extra selection is much less likely to win and can ruin an otherwise solid ticket.

Parlays vs Single Bets

You now know that single bets are easier to win, while parlays are harder. A good approach is to place single bets on your strongest picks, then add one smaller parlay for a chance at a bigger return.

That way, you spread your bankroll across safer bets while still giving yourself a shot at a larger payout.

Responsible Gambling

Betting should be entertainment, not a way to make money. Gambling can be addictive—only bet what you can afford to lose, and never chase your losses. Set deposit, loss, and time limits before you play, and take regular breaks.

If gambling stops being fun or starts affecting your finances, relationships, or wellbeing, seek help immediately.

  • How many selections can you include in a parlay?

    TonyBet allows parlays with up to 20 selections. Smaller tickets are still the better option because they are much easier to hit.
