Hoo Hey How Fish Prawn Crab (Bau Cua Tôm Cá, fish-crab-shrimp) is an offline gambling game using three dice. Players can place their bets on a variety of topics, from food and drinks to cars and houses. They then roll the dice, and if their prediction is correct, they win the bet. If their prediction is incorrect, they lose the bet.

This game is played during the Tet holiday (also known as the Spring Festival or Spring Equinox), which is a celebration of the Vietnamese new year, on the first day of the lunar month. It is usually played by a single player, but in multiplayer mode, players can compete against each other or the computer. The game is based on a board that has six pictures, with each picture having a corresponding side of the dice.
