How Simon works
Simon, originally released in 1978 by Milton Bradley, is one of the most iconic electronic memory games ever made. Each round plays a sequence of colored lights. You must repeat the sequence by clicking the same pads in the same order. Each successful round adds one step.
The average player reaches round 8 or 9 before making a mistake. Reaching round 15 places you in the top few percent of casual players. Very few people reliably pass 20 rounds without writing the sequence down.
