Hangman Electronic Circuit Game

This is the schematic for a circuit that lets you play the Hangman game in the digital domain. Hangman is the game where one player thinks of a word and writes down the number of letters in that word in the form of boxes or dashes. The object of the game is for the opponent to suggest letters of the alphabet, and if they are correct, are placed on the dashes in the correct order so that the word gradually appears. When a suggestion for a letter or number that is not in the phrase is suggested, the opponent is one step closer to a "hanging".

The circuit uses 15 LEDs to create the outline of the man (woman?) being hanged. Once the opponent guesses an incorrect letter, a touch button is pressed, which lights up the LEDs in the correct sequence.
