Cosmobet review for UK players

Cosmobet in short

Cosmobet is a sportsbook run by a Curacao-licensed company, and the register status of that licence is Assessment in progress. The sportsbook has cash out, a bet builder and odds boosts. Its sports welcome bonus carries 15x wagering. To compare it with the rest, open Curacao bookmakers A to Z.

Who runs Cosmobet

Cosmobet is operated by Santeda International B.V., a company incorporated under the laws of Curaçao with Company Number 151296.

The current pages print no operator and no licence. The company and licence details on this page come from earlier pages.

The Cosmobet Curacao licence

Licence number OGL/2024/1798/1048 matches one line on the Curacao Gaming Authority register, and the licensee on that line is the same company.

The expiry date on that line is already in the past. A Curacao licence is not a Great Britain licence. You can run the same lookup yourself with our guide on how to check a Curacao betting licence.

Sports and betting markets

The sportsbook covers sports betting, virtual sports and e-sport. Cash out works on any sporting event, whether prematch, live or virtual sports. A bet builder lets you combine up to 10 markets from a single sport in one bet.

Sports welcome offer and its terms

The sports welcome bonus can only be used on the sportsbook, and the minimum deposit is €/$/£20. The wagering requirements are 15x, the maximum bet is €/$/£1,000 and the expiry is within 30 days.

Two sports boosts sit alongside it:

• Weekly Bet Boost: a 20% sports bonus up to €/$/£200, once per player per week, minimum odds 1.65.
• Cosmic Bet Boost: minimum odds 1.30, maximum reward €/$/£100.

A 200% Express Bet promotion runs from 8 September 2026 to 30 January 2027. The casino side of the brand (casino, live casino and mini games) has its own 400% welcome bonus on slots, with separate terms.

Betting rules and maximum payouts

Cosmobet pays out no more than 100,000 EUR or equivalent on any single bet or spin, including a bonus round or free spin. Winnings from deposit bonuses are capped at 10 times the qualifying deposit, and anything above that is forfeited.

Payments and withdrawals

The minimum deposit is 20€ or an equivalent. Two kinds of payment are named: bank transfer and cryptocurrency, with 8 coins listed (BTC, ETH, LTC, XRP, BCH, USDT, XMR and DASH). Accounts can be played in AUD, BRL, CAD, EUR and USD, as well as those coins.

Withdrawals are made in 3 banking days, and bank transfer payouts follow the same limit. The withdrawal limits are 7,500 € per week and 15,000 € per month, or the equivalent, unless a promotion's own terms say otherwise.

To verify an account, Cosmobet asks for ID, proof of payment systems and utility bills, in Latin or Cyrillic alphabet.

Support and account rules

Support runs by live chat and email, 24 hours a day, 7 days a week. Complaints go to a separate complaints email address and are escalated inside the company when support cannot settle them.

Only one account is allowed per person, household or IP address. Cosmobet reserves the right to charge an inactive account a monthly administrative fee of 5% of the balance recorded on the date inactivity was determined. Players must be 18 or over.

Our take

Rating: 3.4 out of 5, the weighted average of the criteria that could be scored. All six criteria could be scored, so none is left out. Our team tests bookmakers and checks every fact before a page is published.

Pros:

• Licence status, 4 of 5: the register line matches both the number and the company.
• Welcome offer, 5 of 5: a low rollover and a long window to use it.
• Support, 5 of 5: live chat with round-the-clock cover.

Cons:

• Payout speed and limits, 2 of 5: a slow payout time and tight weekly and monthly caps.
• Payment options including crypto, 3 of 5: few kinds of payment named.
• Markets and features, 3 of 5: a short feature list.

Safer gambling

Cosmobet lists account limits, time out periods and self exclusion periods. Help organisations named include Gambling Anonymous, GamCare and Gambling Therapy.

GamStop covers sites licensed in Great Britain, and Cosmobet is not one of them. A bookmaker abroad is never a way around a self-exclusion: if you have registered, keep to it. UK help and tools are on our responsible gambling page.
