One special light gets it's right input value reversed. The special light makes the puzzle interesting.
Anytime a blue light it pressed, all the yellow lights are checked starting at the bottom and then going up. Based on their input values, the yellow lights will change.
You can play for two goals. One is to get all the yellow lights to be lit. The other is to get all the lights, yellow and blue, to be on.
You can reset the game by pressing the R button in the upper left hand corner.
