The only difference in the latest iteration of Rummikub 6 is the 6-player max count. Even though I played with my new Rummikub 6 set a few times after it first arrived, I had to wait until the Christmas holidays to travel to my family home in Rochester, NY to play with a full 6 players. Finally, I can play with my wife, parents, and siblings all at once, and that was what allowed me to put the finishing touches on this review.
