This is a Rummikub game developed as part of the Social & Multiplayer games for NYU.
The object is to be the first to get rid of all of your tiles by melding them in combinations on the table. The possible combinations are:
groups, consisting of three or four tiles of the same number and different colours
runs, consisting of three or more consecutive numbers of the same colour. (Note that unlike some other games, in Sabra the 1 tiles are always low in runs: 1-2-3 is a valid run; 12-13-1 is not.)
No tile may belong to more than one combination at the same time.
Jokers can be used as substitutes for any numbered tile of any colour to make up a valid combination.
A turn consists of either drawing one tile from the pool or melding one or more tiles from hand by placing them face up on the table.
The first meld made by each player must consist of one or more combinations formed entirely from that players hand, where the total numbers of the tiles used add up to 30 or more. If a joker is used, it counts as the number of the tile it represents.
