This is a rare Crisloid Rummikub game set. Probably from the 1970's or 1980's. The tiles are made of hollow, molded plastic with the numbers 1-13 on them and 4 Jokers. Two dice. Discs are still sealed in plastic bag. No instructions manual. A small number of tiles have a little discoloration and the faux alligator case has some minor storage wear.
