What is Bigwintheory and where did it all start?

Bigwintheory came up as an idea with three friends. We all have a big passion for casinos and slots in general. At first we where watching some casino streamers that we saw started doing review sites and such and we thought why should we not do the same since we also love slots? That is the idea from start and now we are here – hoping to start stream casino soon and provide good content for all of our players! Hope that you like what we do and always make sure to have fun while playing. We are doing everything we can to provide you the best content and bonuses out there.
