Play poker hands to build a tower of cards, one floor at a time. Each hand lays a floor piece on the plot. Stack matching suits straight up to grow your multiplier, beat every floor's target and hire a crew on your coffee break. Miss a target and the lot comes down.
A round castle town: the keep at its centre, four seasonal wards around it, one rampart, four gates. You hold one ward; the rest lie under darkness until you last long enough. Four tower schools, eight fusion towers, free-form mazes, 1-4 player online co-op.
