Tranquility is a co-operative strategy game for 1-5 people, suitable for players of all ages, and lasts around 15-20 minutes. Players must collaborate to fill the sea with islands and guide the ship home before any player runs out of cards. Cards must be placed so that the grid ascends in numerical order from bottom left to top right. However, it won`t be that simple, as in the world of Tranquility, the only way to play is in silence. All the players win if they manage to complete the grid and have placed a Start and Finish card. All players lose if a single player can no longer play or discard any cards.
