Invicta's Super-Sonic Mastermind is founded on the original game of the same name. 1-4 players are trying to guess a combination of numbers that has been randomly selected by the computer. When a guess is entered, a response is returned indicating how many digits are correct and how many digits are correct but in the incorrect position. Depending on the difficulty level, players have a limited number of guesses to find the correct "code". The "Super-Sonic" in the name is for an upgrade of the original Invicta Electronic MasterMind that has added a timer and sound effects.
