Mastermind is a strategy game where players compete against each other to guess a symbol or picture that is hidden in a grid. The first player to guess the correct answer wins the game. There are several levels of difficulty, and each level contains a number of clues, or images, that can be used to help the player guess the hidden symbol. There are also hints that can be used in case the player does not have a clue about the next symbol or picture.

The game is based on the concept of artificial intelligence, or AI, which is a computer system that is able to learn and understand human behavior. This is a field of study that has been developing since the 1950s. The goal is to design an AI system that is capable of learning and adapting to the ever-changing environment in which it finds itself.

Mastermind is one of the most popular games in the world and has been played by millions of people. It is a multiplayer game that can be played by two players and has also been adapted for smartphones and tablets.
