tiles and two joker tiles. The number tiles range in value from one to thirteen in four colors (blue, red, yellow, and black). Each combination of color and number is represented twice. Players each have a rack to store tiles without revealing the face of the tiles to the other player(s). Rules The following explanation is based on the rules in the 1998 Pressman American edition: Setup Tiles are shuffled together and either placed into a bag or spread out face down across the table. Each player draws and reveals one tile. The player whose tile has the highest number value will start the game. Tiles are returned to the pool, and players collect 14 random tiles and arrange them on their racks. Play begins with the starting player and proceeds in a clockwise (for modern variants) direction. Play For the first player’s move, they must play a set (or sets in some versions) with a value of at least 30 points. Point values are taken from the face value of each tile played, with the joker (if played) assuming the value of the tile it is being used in place of. A player may not use other players' tiles to make the "initial meld". If a player cannot make an initial meld, they must pick up a single tile from the pool and add it to their rack. Play then proceeds to the next player. Once a player has made their initial meld, they can, on a separate turn, play one or more tiles from their rack, making or adding to groups and/or runs. If the player cannot (or chooses not to) play any tiles, they must pick a tile randomly from the pool and add it to their rack. Players may not make their initial meld and along with that play on groups and runs during the same turn. You can play on runs and groups after the turn of making the initial meld. Players may play tiles by amending sets already in play. The only limit to the length of a run is the extremes of the tile values. Groups are limited to four because colors may not repeat within a group. Sets All tiles in play must be arranged in sets of at least three tiles. The two valid set types are called runs and groups. A run is composed of three or more, same-colored tiles,
