Acigol is a puzzle game in which the player must try to find the hidden ruleset that governs a set of light switches. The only hint the player is given that each switch looks at the state of previous switches. The goal is to turn all the lights on. Once the player has figured it out it's still possible to try out different amount of lamps.
