From the back of the box:
"Refreshingly different, POCKET ENIGMA is the perfect game for TWO adults.
"It's a race to the centre, BUT with a twist; you can sabotage your opponent. See them squirm as you move them back. Yes, at long last the pocket game that brings out the scoundrel in us all.
"The Riddle is the key - the NEW Challenge of the 90's. Some are easy, some fiendishly difficult. Can't solve them? Ask for a clue and see who your friends really are."
Pocket Enigma is a small version of the Enigma game of riddles, with a small board inside the box lid, two pieces, a dice, some instructions, and 500 riddles. The objective is to move your gaming piece through a maze, from a starting point on the outer edge of the board, to the finishing point, at the center of the board. Players take it in turns to roll a die and move their pawn the indicated number of spaces along the track. There are special spaces along the track where a player is asked to solve a riddle.
It is a stand alone game , but it also states on the box that this is an expansion for the original game, adding 500 new riddles to the original.
