This edition of the classic code breaking game offers high quality and superb value for money. The game really needs no introduction, but the idea is to guess the four colour combinations hidden behind the screen. Clues are given by the placing of white and black pegs to signify that a correct colour has been placed in the right place or a correct colour has been put in the wrong place. Given these clues the opposing player has 10 goes to try and crack the code. Players take turns to be either the code maker or the code breaker. The winner is the player who scores the most points over an agreed number of rounds. This game is designed to work as a travel game as all the pieces fit inside the plastic outer case and the nature of the game is that the pieces stay in place during the game in any case. Classic code-cracking fun!
