Visit Cosmobet and the welcome package is the first thing most new players notice, so it's worth setting out exactly what sits behind the headline figure before you deposit a penny. Promotions are one of the main reasons players pick an operator, but the number on the banner is only half the story – the other half lives in the terms, and that's where offers quietly become expensive or straightforward depending on how they're built.
We've gone through the operator's own bonus terms to lay out, in plain numbers, what the Cosmobet welcome package pays, what you give up in exchange, and which of the recurring promotions are genuinely worth a second look. T&Cs apply. 18+. New customers only. Please gamble responsibly (BeGambleAware.org).
The welcome package in plain numbers
Cosmobet splits its welcome offer across four separate deposits rather than one lump sum. Each of the first four deposits is matched at 100% up to 500 €/$/£, with up to 250 free spins attached to each one. That's a potential total of 2,000 in matched funds plus 1,000 spins across the four deposits, provided you make all four.
| Deposit | Match | Free spins | Minimum deposit |
|---|---|---|---|
| 1st deposit | 100% up to 500 €/$/£ | Up to 250 | 20 €/$/£ |
| 2nd deposit | 100% up to 500 €/$/£ | Up to 250 | 20 €/$/£ |
| 3rd deposit | 100% up to 500 €/$/£ | Up to 250 | 20 €/$/£ |
| 4th deposit | 100% up to 500 €/$/£ | Up to 250 | 20 €/$/£ |
The free spins themselves scale with how much you deposit: a deposit of 20–99.99 earns 50 spins, 100–199.99 earns 100 spins, and anything from 200 upwards earns the full 250. Each spin is worth $0.10, and they land on a single named slot, "The Cosmobet Greatest Catch" – worth noting since they're not portable to other titles. Crypto depositors get a separate first-time offer instead: a 200% match up to 1,000 €/$/£ on their first-ever cryptocurrency deposit, with the same 20 €/$/£ minimum.
What you give up in exchange
Here's the part that matters more than the headline percentage. The welcome package carries a 30x wagering requirement on the deposit plus bonus combined, and the crypto offer runs slightly steeper at 35x. On a £500 match that's £30,000 to clear through play before any of it can be withdrawn – a figure worth sitting with before you commit the full deposit.
Three more conditions shrink the offer further:
- You have just 7 days to clear the wagering before it expires.
- Your maximum bet while the bonus is active is capped at 5 €/$/£ per spin – go over it and you risk voiding the bonus.
- The bonus is valid for slots only, so table games and live dealer play won't count toward clearing it.
Even once cleared, Cosmobet's general bonus terms cap what you can actually withdraw from deposit-bonus winnings at 10 times the qualifying deposit. A £20 deposit, in other words, caps out at £200 in withdrawable bonus winnings regardless of how the spins land. That cap applies across the brand's bonus terms generally, not just to the welcome package, so it's worth keeping in mind for any offer you claim here.
Claiming the welcome package
The offer is tied to the deposit itself rather than a separate opt-in step, so claiming it follows the same path as registering an account:
- Sign up and enter an email address, then choose a username and password.
- Accept the terms and conditions and privacy policy to finish registration.
- Make a deposit of at least 20 €/$/£ – each of the first four deposits triggers its own matched bonus.
- Free spins are credited automatically based on the deposit size, and must be used within 24 hours.
Ten games are excluded from bonus play on the welcome package, including Golden Beauty, Bronco Spirit and Reel Heist – play on an excluded title and your wagering progress on those spins won't count. The crypto welcome bonus carries its own, separate exclusion list.
What else runs regularly
Beyond the welcome package, Cosmobet runs a handful of recurring promotions for players who deposit often rather than just once. A 10% crypto cashback applies monthly to net losses from cryptocurrency deposits, credited as a casino bonus with its own 30x wagering requirement and a 7-day expiry. The Spin Quest rewards daily deposits of 50 $/€/£ or more from Thursday through Monday with escalating free spins – starting at 50 on Thursday and building to 90 by Monday – with a bonus 150 spins if all five days are completed.
On the sportsbook side, a 150% sports bonus up to 1,000 €/$/£ is available on a first sports deposit, carrying a 15x wagering requirement and requiring at least three selections per bet at minimum odds of 1.30. A smaller Weekly Bet Boost adds 20% up to 200 €/$/£ once per week on a fresh deposit, at a lighter 10x wagering requirement. There's also a cashback mechanic tied to a specific game, Chicken Race, paying free rounds based on qualifying bet volume.
None of these offers replace reading the terms for yourself – the numbers above are what the operator publishes, but wagering requirements and exclusions change the practical value of a bonus far more than the headline percentage does.
What voids a bonus, and when to skip one
A few conditions can cost you the bonus entirely rather than just slow down clearing it. Players from Thailand, Finland and Japan are not eligible for deposit or welcome bonuses at all. Betting on an excluded game, exceeding the maximum bet while wagering is active, or letting the clearing window lapse all forfeit the bonus outright. If a withdrawal is requested while the total amount wagered since the last deposit sits under three times that deposit, the operator also reserves the right to apply transaction processing costs.
There are genuine cases where skipping the bonus is the sensible choice. If you only plan to deposit a small amount and play briefly, a 30x wagering requirement on top of a 7-day clock can turn a modest deposit into pressure to keep playing past your comfort point just to clear it in time. Declining the bonus and playing with your own deposit, free of wagering conditions, is often the better option for anyone who isn't planning extended sessions.
Whichever you choose, treat any bonus as entertainment value, not as money you're owed. Set a budget before you deposit, and remember that wagering requirements exist precisely because the operator is not giving the match away for free – it's a trade, and it's worth deciding in advance whether the trade suits how you actually play.
