American odds

American Odds, also known as Moneyline Odds, are primarily used in the United States. They are represented either by a positive (+) or negative (-) sign followed by a number. The positive sign indicates how much profit you would make on a $100 bet, while the negative sign shows how much you need to bet to make $100 in profit. For example, +150 means you win $150 on a $100 bet, while -150 means you need to bet $150 to win $100.

European Odds

European Odds, or Decimal Odds, are the most common format used in Europe and many other parts of the world. They are straightforward to understand because the number represents the total payout, including the original stake, per unit bet. For instance, if the odds are 3.00, and you place a bet of €100, you would receive €300 if you win, which includes your €100 stake and €200 in profit.

UK odds
UK Odds, or Fractional Odds, are traditionally used in the UK and Ireland. They are represented by a fraction, such as 5/1 (read as "five to one"), and they indicate the profit relative to the stake. In this example, for every £1 you bet, you would win £5 in profit. So, if you were to bet £100 at 5/1 odds, you would receive £600 in total if you win - your £100 stake plus £500 in profit.
