Buy the board game, be social, the cost will even out
Good game, most of the usual complaints on here are inaccurate (computer favors computer, rigged dice rolls, etc.). The down side is the in-app purchases, gets annoying. But the time you get bored and in-app purchase all the features you might as well have bought the actual board game and played with friends, in real life.
