A welcome package is normally a match: the operator adds a percentage of what you put in, up to a ceiling, sometimes spread over the first two, three or four deposits. The figure on the banner is the sum of all of them at the maximum, which is a number almost nobody reaches.

To get anything like it you have to deposit the maximum every time, in order, inside the window. A package advertised as a four-figure sum across four deposits means putting in that same four-figure sum yourself.

What decides the value is the wagering requirement applied to the bonus, and whether it is applied to the bonus alone or to bonus plus deposit. The same headline figure can be worth roughly twice as much under one of those as under the other, and the difference is one word in the terms.

Watch the maximum bet while a bonus is active, too. It is usually a small fixed amount, breaching it voids the bonus and sometimes the winnings with it, and it is the single most common way people lose an offer they had already cleared.

Gambling is for adults and the minimum age differs by country — it is 21 in Belgium and 18 in most of the rest of Europe. Check the rules where you actually are.

An operator without a licence in your country is not a bargain, it is a counterparty with no regulator behind it. Every national regulator publishes a list; look your operator up before you put money in rather than after.

If it has stopped being a game, most countries run a self-exclusion register that works across every licensed operator at once, and signing up is free.
