What is the Casumo Sign-Up Offer?
Casumo are offering new customers 100% back as a free bet up to £30 when you place your first combo (accumulator) bet.
If your bet loses, you will get the full stake back – up to £30 – as a free bet to use on another combo bet.
To qualify, your first combo bet must include at least 3 selections, with minimum odds of 1.40 per selection, and a minimum stake of £5. The offer only applies to your very first combo bet, so make it count.
