Number Runs In Rummikub you lay down number ‘runs’ from your rack or add to existing sets of numbers on the table. Number ‘runs’ are sets of at least three numbers, of the same colour, that follow each consecutively – for example 1,2,3,4 in red. | Number Groups Number ‘groups’ are tiles of the same number but in different colours. You have to have a minimum of three tiles of the same number but different colour to make a ‘group’. For example, you could add a yellow 5, a red 5 and a blue 5 to make a set. | The Joker The Joker can represent any number or colour tile, but watch out… if the Joker is still smiling on your rack at the end of the game he’ll cost you 30 points! The joker here represents a black 7, meaning you have a full group of 7s. |
