Two welcome bonuses can advertise the same headline figure and still treat a big winner very differently. The reason usually sits in a single line of the terms: the maximum win cap. Some operators express it as a fixed euro amount, others as a multiple of the bonus received, and a few as a percentage of winnings. The format matters as much as the number, because a 10x bonus multiple on a small bonus can cap your payout far below what a plain 1000 euro fixed cap would allow. Reading the cap correctly before you deposit is the difference between a bonus that pays and one that quietly truncates your best session.
How the three cap formats actually behave
A fixed cap is the easiest to read. The terms say something like “maximum withdrawal from this bonus is 1000 euros” and that ceiling applies regardless of whether the bonus was 50 euros or 500 euros. Your upside is transparent: whatever you win above the cap is removed at withdrawal. This format rewards players who take small bonuses with long odds, because the cap does not scale down with the bonus size.
A bonus multiple works the other way. The cap is calculated as a multiplier of the bonus amount, so a 10x cap on a 50 euro bonus produces a 500 euro ceiling, while the same 10x cap on a 500 euro bonus produces 5000 euros. The multiplier is fixed, but the effective ceiling moves with your deposit. That is the trap. Players compare the “10x” figure against a competitor’s “fixed 1000 euro” and assume the multiple is more generous, when on a small bonus it is the tighter constraint by a wide margin. The expression format, not the raw number, decides which cap binds.
A percentage-of-winnings cap is rarer but worth recognising. The terms state that you keep, say, 80 percent of winnings above a threshold, or that the cap equals a share of the total win. This is the most opaque of the three because the ceiling depends on the result itself, and you cannot calculate your maximum payout before you play. When you see this format, treat the advertised bonus as a soft figure and model your expectations on the percentage, not the headline.
Why the cap format changes the value of the same headline offer
Take a concrete comparison. Offer A gives a 100 percent match up to 500 euros with a 10x bonus cap, so the ceiling is 5000 euros. Offer B gives the same 100 percent match up to 500 euros with a fixed 1000 euro cap. On a full 500 euro deposit, Offer A allows five times more upside. On a 20 euro minimum deposit, Offer A’s 10x cap produces a 200 euro ceiling, while Offer B still allows 1000 euros. The ranking of the two offers flips depending on how much you deposit, which is why the cap format has to be read alongside the deposit size you actually plan to make.
This is also where the wagering requirement interacts with the cap. A 45x wagering requirement on the bonus value means you must turn over 45 times the bonus before any withdrawal, and the cap only bites once you clear that hurdle. If the cap is a multiple of the bonus, the same multiplier governs both the wagering target and the payout ceiling, which keeps the maths simple but also keeps small bonuses small on both ends. A fixed cap decouples the two: your turnover target scales with the bonus, but your payout ceiling does not.
For reference, the WELCOME2026 campaign on Netwin activates a 100 percent first deposit bonus up to 500 euros, requires a minimum deposit of 20 euros, carries a wagering requirement of 45x the bonus value, and must be completed within 3 days. Netwin is operated by Netwin Italia S.p.A. Società Unipersonale, which holds ADM GAD concession number 16035, and the brand belongs to RB Holding, headquartered in Sant’Agata sul Santerno near Ravenna. The promotional code identifies the welcome campaign at the point of deposit, so the code and the cap terms are read together, not in isolation; details of that code are set out at https://casino-netwin.it/codice-promozionale/ for reference. The Real Bonus must be wagered again before withdrawal, which is the standard mechanism that keeps bonus funds separate from cash until the conditions are met.
Reading the cap before you claim the bonus
Start with the format, not the figure. Scan the terms for the words “massimo prelievo”, “maximum win”, “cap” or “tetto”, and note whether the value is followed by a currency symbol, an “x” multiplier, or a percentage. A currency symbol means a fixed cap; an “x” means a bonus multiple; a percentage means a winnings-based cap. Each tells you something different about how the ceiling behaves as your deposit changes.
Then calculate the effective ceiling for the deposit you intend to make. If the cap is a multiple, multiply the bonus amount by the multiplier. If it is fixed, the ceiling is the same whatever you deposit. If it is a percentage, apply the percentage to a realistic win scenario. Write the number down next to the wagering requirement, because a generous cap paired with an unreachable wagering target is worthless, and a tight cap paired with a low wagering requirement can still be the better deal.
Check the time window and the minimum deposit together. The 3 day completion window on WELCOME2026 is short enough that the cap only matters if you can realistically clear 45x turnover in that period. A player who deposits the 20 euro minimum and clears the wagering quickly will hit the cap sooner than a player who deposits the full 500 euros, because the multiple-based ceiling is lower on the smaller bonus. That asymmetry is the single most useful thing to understand before you choose a deposit size.
Finally, confirm the licensing and the entity behind the offer. The Agenzia delle Dogane e dei Monopoli, known as ADM, issues the GAD concession, and the concession number 16035 identifies the operator behind Netwin. Registration runs through SPID or the platform’s own verification flow, and the conto gioco is where the bonus, the saldo and the prelievo all sit. A voucher or codice sconto is not the same as a bonus code: the codice promo Netwin identifies the campaign, while a voucher is a separate instrument. Read the termini e condizioni for the cap, the requisito di puntata and the prelievo rules in one pass, and apply the gioco responsabile limits you set for yourself before you deposit.
The practical rule is simple: a fixed euro cap is looser for small bonuses and tighter for large ones, a bonus multiple is the reverse, and a percentage cap is the most opaque of the three. Match the cap format to the deposit you actually plan to make, confirm the wagering requirement and the 3 day window are achievable, and treat the headline bonus figure as marketing until you have read the cap line. The Netwin welcome bonus is only as good as the cap that sits underneath it, and the format of that cap decides whether your best session pays out in full or stops at a number you did not expect.
