Multi Switch: Turn on the lights

For this multi meter I decided to create an interactive logic game. The main goal is to find a way to have all the lights turned on at the same time. Each button has a set of conditionals that turn some of the LEDs on or off. The 3 LEDs receive their power from the Arduino, which also receives the input from the buttons when they are pressed. Through exploration or logic, the user can find a way to solve the puzzle while pressing the buttons in a specific order. This game can be expanded with many more lights, making it even harder to solve each time.
