The game is an adaptation of the real version where the toothpicks taken are replaced by red LEDs and those placed by green LEDs (A popular Brazilian game). When the player activates a key of yours and turns on the green LED it indicates that he has won, and when a player has 3 LEDs lit it indicates that he has no more sticks and with that he won the game. The circuit is powered by batteries but has a reducer for 5 V (diode) since TTL technology is used. One suggestion is to implement the game with microcontroller in a modern version.
