Casumo’s sports welcome offer is a second-chance deal for new customers. Place a qualifying combo bet, and if it loses, you get a 100% refund as a free bet, up to £30. The first bet must have a £5+ stake, include at least 3 selections, and have odds of 1.40 or higher per leg.
Singles do not qualify, and neither do Bet Builders, system bets, each-way, cash-outs, or cancelled bets. The free bet is valid for 7 days and must be used on another 3+ leg combo at minimum odds of 1.40 per leg, with maximum overall odds of 6.00.
While the offer requires a £5 minimum bet, you’ll need to make a first deposit of at least £10. Casumo is one of the many betting sites that accepts PayPal as a qualifying method for their offer. You can also use various other payment methods, including debit cards, Trustly, and PaysafeCard.
Typically, welcome offers credit a free bet after you place a qualifying wager. Casumo is different, as the free bet only kicks in if your first combo bet loses, so it is not a guaranteed reward. The £5 minimum stake is low, though, making it a good option for smaller-stakes players.
Casumo has a separate casino welcome offer, with different conditions from the sportsbook deal. We have outlined the key terms you need to know before claiming the bonus.
New customers can claim a 50% up to £100 casino welcome bonus. To get the offer, you must opt in while making a first deposit of at least £20. The bonus is awarded instantly and expires after seven days. The casino bonus has a 10x wagering requirement, with a £5 maximum bet while it is active. Slots and similar games contribute 100%; table games have a 10% weighting; live casino and video poker contribute 5%; and baccarat does not count. The £20 minimum deposit is a little higher than the £10 entry point you often see. However, the 10x wagering requirement is fair. We also liked that most games contribute towards bonus playthrough, which sets it apart from many other casino bonuses.
Casumo runs ongoing rewards for regular players, with most promos focused on the casino. Sports offers do appear too, but they are more common around major fixtures and headline events.
Spinumo is a daily prize wheel that guarantees a win, with prizes ranging from 1 to 100 free spins. To get a spin on the wheel, you need to have made at least one deposit in the last seven days. The free spins are worth 10p each, expire after 24 hours, and can be used on specified slots. These include player favourites like Starburst, Book of Dead, and Big Bass Splash. Any winnings are paid as cash with no wagering requirements.
Umoboards are Casumo’s exclusive slot leaderboard challenges, designed as a loyalty-style reward for active players. They appear without a fixed schedule. Each board uses its own scoring logic, so the way you play can matter as much as how frequently you play. Rankings update in real time, and formats can vary from spin volume to win-to-bet ratios to the biggest single-win ratio. Prizes go to the top finishers, with multi-value rewards and occasional surprise extras for players as they climb the board.
