Five classic games,each with one twist.

Green Game Studio games keep the rules you know and change one: a floor that collapses, bets that stay sealed, ships that drift, dice that are drafted, a board the tide shrinks.

Every game plays offline, needs no account and shows no ads. Android and iOS, coming soon.
