Unsinkable consists of a single laminated card depicting a blurry image of a naval ship. In the game, the players prepare a certain number of dice, and aim to balance the dice on the ship.
However, for setup, the card is placed floating in water (such as a tub, sink, etc.) On a turn, a player rolls a die and places it in the corresponding section of the ship. If the players are able to place all of the dice on the card without any of the die becoming fully submerged, the players win!
