Simon is a puzzle game that challenges your memory skills. The game was invented by Ralph H. Baer and Howard J and enjoyed success in the 80s. The objective of the game is simple: follow the pattern of lights and sounds and repeat the same combination to move on to the next level. However, every time you make a mistake, you lose the level and have to start over. The game generates a series of sounds and lights randomly, ensuring that the game never ends, and the player can develop their memory with ever-longer combinations. The game also features an unbearable sound and vibration that occurs when you press the wrong button. Simon is available for free on Android.
