Guide How to Play Betting Odds Explained: Decimal, Fractional and American Odds state the contractual return if a selection wins. Decimal 2.50 returns $25 from a $10 stake, including the stake; fractional 6/4 expresses the same price; American +150 expresses $150 profit per $100. Implied probabilities include the bookmaker’s margin, so they do not automatically equal fair probabilities.

Guide Bonuses & Wagering Free Bets Explained: Stake Not Returned and Cash Returns A free bet is a promotional stake governed by the offer terms. Under stake-not-returned rules, a $30 free bet at decimal odds of 2.00 returns $30 profit, not the $60 total a cash stake would return. Check the qualifying bet, minimum odds, expiry, eligible markets and any wagering on resulting winnings.
Sports betting — frequently asked questions
What should I verify before using a betting site?
Match the legal operator and exact domain to the official register for your location. Then check current betting rules, account controls, withdrawal terms and the complaints route. A supplied regulator label is a comparison field, not a CasinoSherpa licence check.
Are betting bonuses and free bets worth their face value?
Not automatically. Some free bets do not return the promotional stake, and odds, qualifying-bet rules, expiry and withdrawal restrictions all affect value. Work from the current offer-specific terms rather than applying a generic percentage.
How do you rank betting sites?
The published Sherpa Score blends the supplied rating (50%), calculated bonus-value band (35%) and supplied payout-speed band (15%). These catalogue inputs are not proof of current quality or suitability.
