Improve your problem-solving skills with our brain game Mastermind. Brain training with Mastermind helps you to train your problem-solving skills in a fun way. Use logic to solve the code in as few steps as possible. This mainly concerns the identification and evaluation before you take the next step. You regularly use your problem-solving abilities and logic in daily life. This happens, for example, when the bus that you normally take to work does not run and you quickly have to find an alternative method to get to work on time.
