We tested the first deposit bonus for every UK online casino to determine which casino has the best ROI for new depositing players. We took every casino’s first deposit offer and ran it through our custom formula to determine it’s actual value (ABV) when depositing £100 into a new account. Here is how MonsterCasino UK performed in our ABV100 test.

Unfortunately, MonsterCasino Casino’s welcome bonus for a first deposit of £100 requires you to risk so much more than you deposited that it earned it a negative Actual Bonus Value (ABV). The actual value of MonsterCasino Casino’s welcome bonus was -£1.53.

– 21 Casino: If you’re looking for the largest possible welcome bonus value, they won our the United Kingdom max bonus test.
– 21 Casino: If you’re more cautious with your first deposit, they won our UK online casino welcome bonus test for first deposits of £100.

MonsterCasino Casino’s first deposit bonus was valued at -£1.53 in our bonus test. This was good for 55th out of 133 online casinos which we tested from the United Kingdom with a baseline first deposit of £100. MonsterCasino Casino’s first deposit bonus finished in the top half of tested casinos, but its bonus was not quite as good as other casinos. An ABV100 of -£1.53 is approximately £34.47 more than the the United Kingdom average first deposit bonus — a good result, but not the best.

How quickly and often does customer service respond to emails at MonsterCasino Online Casino?

MonsterCasino Casino was below average when it came to responding to customer support questions via email. In fact, its reply percentage 40% was 60% less than the average online casino in the United Kingdom.

Bonus and Promotions Test

For our UK online casino bonus and promotions test, we considered and included both no deposit bonuses and first deposit promotions at each online casino. For the first deposit bonus, we used a standard £100 deposit as the baseline since each casino has its own maximum deposit eligibility for first deposit bonuses.
We call our calculation the Actual Bonus Value (ABV) and it includes different metrics and playthrough requirements depending on the bonus we’re evaluating. The ABV100, for example, looks at the value of a bonus if we deposit £100.
Below are MonsterCasino’s bonus and promotion test results.
