Title from label.
"Magic Numbers features two logic games on one cartridge: Mind Reader and Nim. In Mind Reader, players must guess a mystery number of varying length. The computer will signal which digits are in the proper position or which need to be transposed for each incorrect guess. In Nim, two opponents take turns removing items from a number of piles. The player who removes the last pile from the table wins."--All game guide
