Codebreaker is a video game released in 1978 by Atari, featuring three distinct games, each with six variations: Bagels, Nim, and Mastermind. In each game, the player must take turns guessing a numerical code and entering it using the keyboard controller.
The games can be played in single-player mode or in a two-player mode, where the players cooperate to solve the puzzles. The objective of each game varies:
- Bagels: The goal is to guess a secret code consisting of a sequence of digits. After each guess, the game provides feedback in the form of the number of correct digits and correct positions. The player must use this information to deduce the secret code.
- Nim: In this game, the player faces off against the computer in a battle of wits. The objective is to force the opponent to pick up the last object from a pile. Players take turns removing objects from the pile, and the one who takes the last object wins.
- Mastermind: The goal is to crack a secret color code created by the computer (or the other player in two-player mode). The player must guess the sequence of colors, and the game provides feedback on the number of correct colors and their positions in the sequence.
Each of these games offers a unique challenge, requiring logic, strategy, and deduction skills to solve the puzzles and outwit opponents.
