Casumo Casino Online UK Casino Review & Bonus

We measured the return new players could expect to receive from a first deposit bonus at every UK online casino. The value of each first deposit bonus was determined by running the welcome bonus offer and conditions through a custom formula which we call ABV100 to determine exactly how much you should expect from a first deposit bonus when you make a £100 deposit. This is how well Casumo Casino did in our first deposit bonus test.

Casumo online casino earned a negative bonus value in our TBV100 test which means that due to the wagering requirements and other bonus terms, you risk losing more than you deposited. With a value of -£23.7, it’s unlikely that you’ll earn much money from Casumo Casino’s welcome bonus.

– 21 Casino: Won our max casino bonus test with a bonus value of £61.71.
– Best Value Promotion: 21 Casino won our casino bonus value test for a £100 first deposit.

Casumo Casino did not rank in the top 50% of our first deposit bonus test, and its bonus value of -£23.7 was only good for 99th place. We based this ranking by using our Actual Bonus Value formula and a £100 first deposit amount. While you can still do worse than Casumo Casino, it’s first deposit bonus value of -£23.7 was -£7.3 less than the average casino in the United Kingdom. You can find a better first deposit bonus.
