CasinoKings Casino Online UK Casino Review & Bonus

The welcome bonus from CasinoKings UK online casino had a negative actual bonus value (ABV) in our ABV100 test — meaning players stand a high chance of losing more than their £100 first deposit. We found that its bonus was actually valued around -£13.81.

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.

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.
