This is a the classic "copy the sequence of coloured lights". Originally called Simon.
There are coloured lights, each with its own button. The computer picks a random colour, which the player then has to copy (by pressing that colour's button). The computer then picks another colour, and adds it to the original. Now the player has to copy both colours. This continues, with the sequence getting longer and longer until the player gets it wrong, at which point the game is over.
