Bright Circuit
Bright Circuit is a compact light-switching puzzle. A click changes the selected lamp and its neighbours above, below, left and right, so fixing one corner can undo progress elsewhere. Lights up mode asks you to turn every lamp on. We solved a four-by-four board in five moves, then used Play again to start a fresh board with the move counter reset. Blackout mode changes the target to every lamp off. Read the current goal before planning a sequence instead of treating every glowing lamp as progress. Desktop mouse input was tested; phone controls and completing the harder board were not.
How to Play Bright Circuit
Click a lamp to toggle it and its orthogonal neighbours. In Lights up mode turn all lamps on; in Blackout mode turn all lamps off. Use Restart or Play again for a new attempt, and the mode button to change the target.
