Basic Gameplay: Simon is a memory based game. Once the 'Play' button is pressed, the game board will highlight one of the coloured game pads. The player must then copy the computers selections. If the correct pad is selected by the player the computer will then play the pattern again adding an additional pad press to each turn.

Difficulty Level: In this version of the game selecting the 'Normal' option runs the game for 10 rounds, if you guess ten consecutive pad presses correctly you win the game. If you select the hard option the level required to win doubles to 20 correct consecutive pad presses.

Once you win or lose it will display on screen and all lights will flash. The 'Play' button will then become selectable again to start a new game.

The original Simon is an electronic game of memory skill invented by Ralph H. Baer and Howard J. Morrison, working for toy design firm Marvin Glass and Associates,[1] with software programming by Lenny Cope. The device creates a series of tones and lights and requires a user to repeat the sequence. If the user succeeds, the series becomes progressively longer and more complex. Once the user fails or the time limit runs out, the game is over. The original version was manufactured and distributed by Milton Bradley and later by Hasbro after it took over Milton Bradley. Much of the assembly language was written by Charles Kapps[citation needed], who taught computer science at Temple University and also wrote one of the first books on the theory of computer programming. Simon was launched in 1978 at Studio 54 in New York City and was an immediate success, becoming a pop culture symbol of the 1970s and 1980s.
