Sports betting: odds, markets and the conditions behind offers
Alongside the casino, many platforms offer sports betting. The rules are different from games: the result depends on a real event and the price of a bet is the odds. Sportsbook bonuses also have clauses of their own, explained in this section.
Sports betting is legal only in some countries and often only with locally licensed operators. This section explains markets and conditions; it gives no tips and is not an invitation to bet.
Reading decimal odds
Decimal odds of 2.50 on a 10 stake return 25 if the bet wins, stake included (illustrative example, not Joe's actual terms). Odds also contain the operator's margin: the implied probabilities of all outcomes add up to more than 100%, and the excess is the margin.

A free bet, worked through
A 10 free bet at 3.00 that wins pays 20, not 30: the free stake is not returned (illustrative example, not Joe's actual terms). It is the most common gap between expectation and reality in sportsbook offers.

Account limits for betting
The same tools that apply to casino play apply to sports: deposit limits, time limits, cool-offs and self-exclusion, sometimes by product category. If betting is the part of gambling you find hardest to control, ask whether the operator lets you exclude sports only.
Margins add up
Because each selection carries the operator's margin, combining several selections multiplies it. That is the structural reason bonuses requiring accumulators are expensive to clear. Clause glossary: Bonus terms.
