Wagering requirements, computed before you accept

Take an illustrative bonus of one hundred dollars at a thirty-five-times requirement. Before anything can be withdrawn you must place bets totalling 3,500 dollars — thirty-five times the bonus. Now bring in the house edge from our house-edge guide: cycling that much money through a game keeps a predictable slice of it. That expected cost, not the headline amount, is what the bonus is worth to you; run the numbers and many offers price out negative before you have clicked anything.

Beyond the multiple itself, read for: game weighting (slots often count fully, table games a fraction or nothing); maximum bet caps while wagering, whose breach can void winnings; time limits on completing the playthrough; and whether the requirement applies to bonus only or to deposit plus bonus — the same multiple on the doubled base is twice the obligation. The UK regulator's technical standards (RTS 3) exist precisely because the likelihood and the rules must be visible to the player — read the rules with that entitlement in mind.

A bonus is worth accepting when the expected cost of the playthrough is smaller than the value you place on the extra play, and you would have made those bets anyway. It is worth refusing when the multiple forces you into games, stakes or a pace you did not choose. Most operators let you decline a bonus at deposit — the option nobody advertises and the one seasoned players use most.
