Welcome bonus
A welcome bonus is an offer a casino or bookmaker makes only to new customers, usually a percentage match on the first deposit, a set of free spins, or both, released under conditions you must meet before any winnings can be withdrawn. The headline figure tells you what is added to your account. The terms tell you what it costs to get it out, and that second number is the one that decides whether the offer is worth taking at all.
How a welcome bonus is calculated
Most casino welcome bonuses are a deposit match. A 100% match up to €100 means a €100 deposit brings €100 in bonus funds, while a €50 deposit brings €50; the cap is the ceiling, not a guarantee.
The wagering requirement is what turns that figure into a real cost. It is a multiplier, and operators apply it to different bases, which is why two offers with the same multiple can differ by double.
Take 40x on a €100 bonus. If the multiple applies to the bonus alone, you must place €4,000 of bets before withdrawing. If the clause reads “wagering applies to deposit plus bonus”, the base becomes €200 and the requirement becomes €8,000. Same headline, same multiple, twice the turnover, and the only difference sits in four words of the terms.
Read the base before the multiple.
The other numbers in the terms
Game weighting decides how much of each bet counts: slots commonly count in full, while table games and live casino often count for a fraction or nothing, though the exact percentages vary between operators. A maximum bet rule caps each stake while the bonus is active, and breaking it can void the winnings. Many offers also cap what bonus play can pay out, and set a deadline after which unused bonus funds and any progress towards them are removed.
Where you meet it and what it is confused with
You meet a welcome bonus at sign-up or on the first deposit screen, sometimes as a box to tick and sometimes applied automatically. If you would rather play with your own money only, look for the opt-out before you pay, because removing a bonus afterwards can mean forfeiting what it touched.
A no-deposit bonus is often filed under the same heading, but it is a different offer. It needs no payment, is usually small, and tends to carry a tight cap on what you can withdraw. A reload bonus works like a deposit match but is offered to existing customers on later deposits.
The sticky and non-sticky split is the distinction that matters most to your balance. With a non-sticky bonus your own deposit is played first, and you can usually withdraw winnings from it before the bonus money is touched. A sticky bonus cannot be withdrawn at all; it is removed from the balance when you cash out, so only the winnings above it leave the account. Which type an operator uses is set out in its terms, and it is not standard across the market.
On a sports betting site, the welcome offer is more often a free bet, where the stake itself is usually not returned with the winnings.
Welcome bonuses under Irish law
The Gambling Regulation Act 2024 treats a welcome bonus as an inducement, which section 157 defines as a benefit or advantage meant, directly or indirectly, to encourage participation in gambling.
Under that section a licensee may not offer an inducement to a person or a specific group of persons, and the Gambling Regulatory Authority of Ireland may make regulations setting conditions on inducements offered to the public, or banning classes of them. Its obligations apply to operators once the relevant provisions have commenced and the operator holds a GRAI licence, and the inducement rules have been brought in on a separate timetable from licensing. Until they are in force, the shape of an offer depends largely on where the operator is licensed, so check grai.ie for the current position rather than relying on any one site’s description.
Whatever the law says on a given day, a welcome bonus is a reason to deposit sooner and play longer. Set a deposit limit before you claim one. If gambling has stopped being something you control, the HSE gambling helpline is free on 1800 753 753.
