The game "Gourd-Crab-Fish-Tiger" is a Vietnamese gambling game using three dice.

The six sides of the die, instead of showing one to six pips, have pictures of a fish, a prawn, a crab, a rooster, a calabash gourd, and a stag. Players place wagers on a board that has the six pictures, betting on which pictures will appear. If one die corresponds with a bet, the better receives the same amount as their bet. If two dice correspond with a bet, the better receives two times their money. If three dice correspond with a bet, the better receives three times their money.
For instance, if you place $3 on fish, and the dealer rolls 2 fish and one stag, then you would get an additional $6.

"Gourd-Crab-Fish-Tiger" is similar to the dice game Crown and Anchor played by British sailors, or chuck-a-luck played in America. Bau cua tom ca is often played at Tết (Vietnamese New Year).
