Casumo Casino has out from the pack ever since its conception back in 2012. Its main appeal from the start has been its unique gamified Adventure, which allows players to earn points by playing casino games which they can then use to level up, receive bonuses and unlock new content with throughout the casino. Added to this the fact Casumo offers a £1,200 welcome package with 200 extra spins, and you get one of the most attractive casinos online.
