The game was originally published in GAMES with the rules for two two-player games (The Basic Game and Solomon Nim) by Gardner and one (Son of Solomon) by Sackson. There were also two solitaire games and some puzzles.
Kadon describes their version like so:
"We're honored to have an exclusive of this game invented by the beloved author of countless books on recreational mathematics. The hand painted, 15" square fringed game cloth (washable) serves for four games for 2 players, plus a variety of jumping and positional puzzles for solitaire. The title game lets players invade the opponent's castle, capture as in checkers. Another game is an unusual version of "Nim". And "Caravan" is a desert-crossing trek, with strings attached. The 18 solid hardwood maple disks are hand-tinted in 3 colors. Directions are on a "scroll"."
Caravan is new to the Kadon edition, as is the three-player game, if different. Son of Solomon is presumably not included in this edition as it requires numbered pieces.
