Players lay down runs and sets on a game board marked out in a grid with each player having his own color quadrant. The runs and sets can tie together like a crossword puzzle. The player to go out first gets to score all the runs and sets that start in his own color as well as any that may connect with them regardless of their location on the board. The first to reach 500 points wins. This is the game that ties Rummy to Scrabble and makes it loads of fun.
