Terms and multiplier

How to read a welcome bonus before accepting it

A 100% with a requirement of 80 times is dearer to clear than a 200% with a requirement of 60: the headline percentage decides nothing, it is the multiplier, the calculation base and the maximum stake that decide.

The auditor bull, reading the small print of a long unrolled contract

The percentage that appears in the headline of a first-deposit promotion is the easy part. Online casinos with a welcome bonus publish an eye-catching number, but that number does not say how much the offer costs to clear. What decides whether a promotion is worth taking is the wagering multiplier, the base it is calculated on and the per-round cap that applies while bonus balance remains. That last clause cancels most bonuses out.

Vave is this site's featured partner: its row comes first and is marked, and it is the only casino the site links to. The other rows are not ordered by quality. A cell with no figure means the operator does not publish that detail, or that we have not read the document where it would sit; it never means zero.

Vave is this site's featured partner and the only casino it links to. The “Open” button on any row leads to the same place: to the casino that sponsors this page, not to the operator printed beside it. The “Read” link does lead to our own review of that row. On 28 August 2026 we withdrew about 5,000 USDT from Vave with no document asked for: that is one withdrawal on one date, and clause 8.7 still stands.

The wagering multiplier is not a minor detail

Anyone searching for an online casino welcome bonus tends to look at the percentage: 100%, 200%, or whatever the operator advertises. The percentage only indicates how much extra money is added to the deposit. It does not say how many times that money has to be wagered before it can be withdrawn. That figure is the multiplier. It appears in the terms and conditions, not on the banner. If the multiplier is not published, the offer cannot be compared with others. In Spain, the legality of online casinos requires the conditions of promotions to be clear, but the level of clarity varies between operators.

Online casino bonuses are not free money. They are a deferred wagering contract. The multiplier is applied to an amount, and that amount may be only the bonus sum, the deposit plus the bonus, or even the winnings generated. Before accepting, it is worth reading that particular line. The multiplier and its base are read together for each operator in the best crypto casinos compared.

Wild.io's promotions page listing its current bonus offers and their headline conditions — The banner adds up to 350% and 200 spins. The clause that sets how much has to be played before withdrawing is not on this page but in separate terms.

What the wagering requirement is calculated on

The calculation base is the second figure that decides whether the promotion is reasonable. The same multiplier, for example, does not produce the same result if it is applied only to the bonus or to the deposit plus the bonus. Some online casino promotions use the least favourable base and bury it in a long paragraph. Others include the bonus winnings in the base, which multiplies the total amount to be wagered. There is no standard figure in the Spanish market. Each operator licensed by the Dirección General de Ordenación del Juego (DGOJ) decides its own formula, always within the Gambling Act 13/2011 on gambling.

Ambiguous small print on this point ought to raise suspicion. The restricted countries clause has not been confirmed one by one; read the terms before depositing. If an operator does not publish the calculation base in an accessible way, there is no way of knowing the real cost of the promotion.

The maximum stake allowed cancels most bonuses out

The maximum stake while the bonus is active is the clause that invalidates the most promotions. Many online casinos with welcome bonuses limit each round to a low amount, often lower than the one you would use with your own money. If you go over that limit, the operator can cancel the bonus and the winnings attached to it. It does not take a huge stake to breach it; an ordinary round on a medium-volatility slot is enough. The stake limits for high roller players are especially incompatible with these promotions.

This clause usually appears separately from the multiplier, in a section on “bonus use” or “valid bets”. It is not advertised on the registration page. Anyone who does not read it can meet the whole multiplier and still see the bonus cancelled when they request a withdrawal. Fast withdrawals after the bonus depend on no intermediate limit having been breached.

The Betpanda.io home page: a weekly cashback banner with a countdown, a strip of recent big wins and featured slots — Captured on 25 August 2026. The banner sells the account itself — anonymous and without limits — which is a coherent pitch for the only operator here with no gambling regulator behind it. Before taking up the invitation, read the terms: it is the operator who decides what happens to the balance afterwards.

What the rules say in Spain

The DGOJ requires the terms of promotions to be published before the player accepts them. In Spain, all bonus figures are expressed in euros (€). The Gambling Act 13/2011 on gambling sets the framework, but does not fix a maximum multiplier or a specific maximum stake. That means two legal casinos can offer bonuses with very different costs. The comparison is not made by looking at the percentage; it is made by reading the multiplier, the base and the maximum stake.

No-deposit offers, the ones given on registration, are also subject to these rules. A gift balance does not remove the wagering requirement; it only changes the initial amount it is calculated on. That kind of promotion tends to come with higher multipliers and lower maximum stakes. It is not a worse offer by definition, but the cost of clearing it is calculated in the same way.

In the event of a dispute over a promotion, the player can turn to the DGOJ or to the FEJAR helpline. The law does not turn a bonus into an automatic right to withdraw; it turns the published terms into a contract the operator has to honour.

How to check before depositing

Before accepting any first-deposit offer, it is worth opening the terms and locating three data points: the multiplier, the calculation base and the maximum stake allowed. If any of them is missing, the offer can be discarded. New online casinos sometimes publish more aggressive bonuses, but the terms remain the only reliable criterion.

The game contribution table is the fourth data point, and it is usually on another page: online slots tend to count at 100% and table games at a fraction or at nothing. Casinos that accept cryptocurrencies may add specific conditions about conversion into euros or about the volatility of the deposit. Those conditions are also part of the bonus. The point is not to avoid every promotion; it is to know what you are accepting.

At Mejores Cripto Casinos nobody plays. The terms and conditions are read and the clauses are compared. A welcome bonus is a contractual offer, not a gift. The headline percentage matters least of all. The multiplier, the base and the maximum stake are what is left once the advertising is gone.
