Simon challenges players with each new color sequence. To defeat Simon, players must remember the pattern well and then press the colorful buttons in the correct order to repeat it. The game starts with a simple sequence, but the light patterns become increasingly difficult as the game progresses, raising the tension with each round. Every time the green light flashes, the player earns a point. If all the lights illuminate simultaneously, they score 10 points. Simon saves the high score to challenge friends or to beat their own high score repeatedly.
