24 cards, each of them showing four bubbles in four different colours (red, green, blue, yellow), are laid out on the table. Four dice, in the same colours, are rolled. Their faces show values from 1 to 24. All players then simultaneously try to find the card on which the bubbles' sizes match the die roll. E. g. if the green die shows the highest value, the blue one the second highest, the red one the third highest and the yellow one the lowest, players have to find the card on which the green bubble is the biggest, the yellow one is the smallest etc. The player who is first to find the correct card puts it in front of him/herself. If the same combination is rolled again, another player can steal the card. The first player to collect (and keep!) four cards wins the game.
