The Game is a logic-based puzzle experience where your objective is to resolve a complex electronic circuit by achieving a state of total darkness. Each level presents a unique configuration of power switches, logic gates, and lightbulbs interconnected on a digital grid.
You interact with the Game by toggling the state of power switches to redirect the flow of energy through the system. As signals propagate through AND, OR, NOT, and other Boolean logic gates, the state of the connected lightbulbs will shift. A level is successfully completed only when every lightbulb in the configuration has been successfully deactivated. Success requires analyzing the logical dependencies of the circuit to identify the specific combination of switch states that results in a complete system shutdown.
By playing, you acknowledge that the challenge of Lights Out—including Boolean algebraic reasoning, signal propagation analysis, and the necessity of mastering complex logical operators—is an intentional part of the Game's design and core experience.
A stable internet connection may be required to load ads or complete purchases.
There are no strict age restrictions. Players are responsible for complying with local laws regarding age-appropriate content and consent.
We may update these Terms from time to time. Continued use of the Game constitutes acceptance of any updated Terms.
These Terms are governed by the laws of Singapore. Any disputes arising under or relating to these Terms will be resolved exclusively in the courts of Singapore.
