Not All Bets Are Created Equal
When you first visit a sportsbook, the range of bet types on offer can feel overwhelming. Moneylines, spreads, parlays, teasers, round robins — what does it all mean? This guide breaks down the most common types of sports bets so you know exactly what you're placing and why.
Single Bets (Straight Bets)
A single bet (also called a straight bet) is the simplest wager: you're betting on one outcome in one event. Win and you collect; lose and you move on. Singles are the foundation of disciplined betting because you can evaluate each selection on its own merits without compounding risk.
Best for: Beginners, value-focused bettors, bankroll management.
Parlay Bets (Accumulators)
A parlay (called an accumulator or acca in the UK) chains multiple selections together. All picks must be correct for the bet to pay out. The appeal is the multiplied odds — a 4-team parlay at -110 each pays out at roughly +1228. The risk, of course, is that one wrong pick kills the entire bet.
- Pros: Large potential returns from small stakes
- Cons: Much harder to win; sportsbooks hold a much higher margin on parlays
Best for: Entertainment bets with small stakes; not recommended as a primary betting strategy.
Teaser Bets
A teaser is a modified parlay available mainly in American football and basketball. You get to move the point spread in your favour by a set number of points (typically 6 in NFL), but in exchange, the payout odds are reduced. For example, you might move a -3 favourite to +3, making the bet much easier to win — but you're still linking multiple teams.
Teasers that cross key numbers (3 and 7 in football) are particularly popular among strategic bettors.
Round Robin Bets
A round robin creates multiple smaller parlays from a group of selections. For instance, selecting 4 teams in a round robin creates every possible 2-team and 3-team parlay combination. It's more expensive but provides partial payouts if not all selections win.
Futures Bets
A futures bet is a wager on a long-term outcome — a season champion, award winner, or division title. These are placed well in advance and your money is tied up until the event concludes.
- Higher potential payouts than game-by-game betting
- Opportunity to find value early, before public opinion moves the line
- Long wait for resolution; opportunity cost of capital tied up
Prop Bets (Proposition Bets)
Props focus on specific outcomes within a game rather than the final result. They come in two main forms:
- Player props: Will a player score? How many yards/points/assists will they record?
- Game props: Will there be a safety? Which team scores first? Total first-half points?
Props are fun and varied, but typically carry higher vig than main markets. Research matters — deep knowledge of a specific player's recent form and matchup can provide a genuine edge.
Live / In-Play Bets
In-play betting allows you to place wagers after a game has started, with odds updating in real time as the action unfolds. This opens up tactical opportunities — for instance, if a strong favourite goes down early and their odds lengthen, you might find value backing them to recover.
In-play requires fast thinking and discipline to avoid impulsive bets driven by what you've just seen.

Which Bet Type Should You Use?
For most bettors, singles should form the core of their activity. Other bet types can complement your strategy, but understanding the risk and margin of each type is essential before diving in. Start simple, track your results, and add complexity only once you're comfortable with the basics.
