Hop aboard the ship Tranquility for a co-operative card game where players aim to fill the sea with numbered island cards and guide the ship home. Players must maintain silence as they strive to complete the grid before any other player exhausts their actions. Victory is achieved by placing cards in ascending numerical order from bottom left to top right, with a Start and Finish card placed to win collectively. Should any player be unable to legally play or discard cards, all players lose.

Turns move clockwise, starting with the quietest player. Actions include playing a card or discarding two cards, followed by drawing back up to five cards. Ensure the grid ascends numerically by placing cards adjacent to existing ones. If the difference between numbers requires discarding, players do so from their hand. Remember, communication is off-limits.
