The reason for the game being packaged in a tin (other than to fool me into thinking I had a little something to accompany my coffee) was because it was a 25th anniversary limited edition - and it did make it feel special.
Inside the tin was a playing board, maze tiles, treasure cards and four plastic, coloured playing pieces in the shapes of mystical figures.
The game took a bit of getting used to because instead of moving the pieces around the board in the conventional manner, the board layout itself moves around. The idea is to move the maze to enable yourself to travel around and be the first to collect all your pieces of treasure. The maze is moved by inserting one maze tile in one of 12 places around the edge of the board thus sliding the whole row of tiles along one position. This one move can have a dramatic effect on the maze which hopefully works to your advantage (and if you're lucky/skillful/evil, to the detriment of opponents!)
Labyrinth is a game for 2-4 players of 7+ years. It certainly kept three teenagers thoroughly entertained and away from their laptops for a good half hour!
