Let's load our luggage, but don't let the ship tip!
Players alternately place their luggage on the 3D ship. The deck is always on a slope where the luggage is put, so place carefully. If the ship tilts, the player has to take a ship's chest and add it their own luggage as a penalty. The ship tilts easily, so it's a race to load luggage before the ship tilts. If a player finishes placing all their luggage or the penalty chests run out, the game ends.
Since each of the different luggage items is a different material like brass, aluminum, iron, glass, acrylic, and wood, the strategy and fun of the game is guessing the weight right as to not tip the ship.
