Mr Green Casino will now be available on Facebook launching its first social casino.
Spin Tower Casino presents "a new generation of one-arm bandits" and deals in virtual currency.
“Social casino gaming is expanding in leaps and bounds. In our assessment, Spin Tower Casino has the potential to attract a significant share of social casino gamers, both those playing existing products and entirely new gamers,” said Mikael Pawlo, chief executive officer of Mr Green & Co.
“Spin Tower Casino is part of Mr Green & Co’s strategy of investing in more products and brands in online gaming, which is our core competence. We are continuously looking for and evaluating projects and products in this area.”
