Welcome to the best restaurant in the city! Guests can't wait to be seated and eat, so you need to work fast.
In Boom Boom, players try to complete sets of cards at the same time. When you complete a stack, ring the bell; for the second stack, ring twice. How many stacks do you still need? Oh no! Someone rang the bell again. Who will end the game?
Each player starts the game with a number of face-down card stacks, while the game board has four face-up cards on it. Playing at the same time, everyone looks through one of their stacks, exchanging one card from the chosen stack with one face-up on the board, if desired. Players can look through new stacks as they like, but only one stack at a time. As soon as you have a stack of four cards with the same person, ring the bell! The player who completes all of his stacks first wins.
