First of all before you take any actions – check if they have a trademark on Bingo Night Live.
If they do – then you have problems from a legal point of view and then your best bet is trying to get them to buy the domain from you. If you try making money from the domain their lawyers will eat you up.
If they don’t – the sky is the limit… you could SEO the hell out of that domain and get a nice chunk of the organic search engine traffic for it and direct traffic to the real site or put a list of other bingo sites.
I reckon that you could possibly pass their site on search engines as you have an exact match on the domain.
Anyway – good luck
