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.
Below are TheOnlineCasino’s bonus and promotion test results.
