The welcome bonus offer is one of the key advantages that online casinos hold over their land-based counterparts. The welcome offer is usually a deposit match which allows you to double or even triple your casino balance . You can claim hundreds of pounds that way, something impossible in brick-and-mortar casinos. But you have to ask yourself: is there a catch?

It turns out that welcome bonuses are also one of the primary sources of frustration for most casino players. We see that often on the casino forums where we post and the questions we receive from our readers. There are many wagering terms and playthrough requirements which you need to be aware of.

Our ranking of the UK’s best online casino bonus offers is prepared based on a detailed check of the underlying terms and conditions. While comparing just the sums of the available offers is easy and can be done by any bonus hunter, we keep track of the fine print that most players miss.
