Codebreaker is a game released for the Atari 2600.


There are two different games on this cartridge: Codebreaker and Nim. In Codebreaker, you must guess the correct three- or four-digit number by the clues the computer gives you as far as right numbers and right positions within a certain number of guesses. In Nim, you and your opponent take turns removing objects from distinct heaps. On each turn, a player must remove at least one object, and may remove any number of objects provided they all come from the same heap.
