    Online sports betting is a constantly evolving landscape, within the past few years, we’ve seen things like live/In-play betting and mobile betting apps become front and center of the industry.

    With an increasing number of online oddsmakers popping up, it can leave bettors confused as to where to begin wagering. It’s so easy to access the odds nowadays, but where’s the best place to do so?

    Bettors will often find odds offered in the form of American odds. However, they may also encounter Decimal and Fractional price formats, which are as follows:

    • Decimal Odds: Popular in Europe and Canada, bettors calculate their payout by multiplying the odds by the stake. As an example, 3.50 odds X $100 wager returns a $350 profit.
    • American Odds: Often referred to as Money Line odds, American pricing uses $100 wagers as a baseline. Presented with +/- numbers; a negative line highlights the favorite, while a positive line represents underdogs. Betting on +350 odds returns a $350 profit on a $100 betting ticket.
    • Fractional Odds: Mostly used in the United Kingdom, as the name suggests, this betting line format is presented as fractions. As such, a +350 in American odds wager would be displayed as 3.5/1.

    Simply put, sports betting odds are the simplest terms of how the outcome of a sporting event may unfold. The odds reflect the probability of any competition and are often used as a benchmark for understanding who is due to win and lose.

    Types of Sports Odds and Markets Available in Sportsbooks

    There is almost a limitless number of sports betting odds, from your standard Moneyline, Against the Spread, and Totals options, to the more obscure markets like Parlay and Accumulator bets.

    The emergence of LIVE betting has given rise to a whole new way of wagering, allowing bettors to select very specific In-play markets. For example, bettors can now wager on the number of catches a certain player will make within a specific soccer match— as it happens!

    The improvements we see in technology in mainstream life have directly affected the sports betting world, as players can now enjoy the fruits of mobile betting technology—wagering on live markets as the game unfolds in front of them.

    As well as through mobile devices, LIVE betting markets are accessible through desktop sites with nearly all online bookmakers in operation today. In-play betting isn’t just available for major sports lines like tennis, but also for less popular sports such as table tennis and cricket.

    Not only that, but bettors will be able to access another highly popular betting line, which is futures markets. These markets allow you to wager on the outcome of events before they have even begun, focusing on league championships, playoffs, and player markets—such as MVPs or top scorers.
