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 controls and touch lamp switching and Restart were tested. Use landscape on phones because the portrait mode-button labels overlap. Mobile checks used Android Chrome touch emulation; physical phones, iOS Safari and completing the harder board were not tested.
How to Play Bright Circuit
Click a lamp with a mouse, or tap it on a phone in landscape, to toggle it and its orthogonal neighbours. In Lights up mode turn all lamps on; in Blackout mode turn them off. Use Restart or Play again for a new attempt. Swipe the page margin to reach controls above or below the board.
