Game of Bulbs
Click the figures to set the initial and target bulbs. A click in those regions turns a bulb on or off.[more]
Set the game by clicking "establish initial bulbs", then try to reach the target bulbs by clicking the buttons under "game".
Under "game", clicking a corner changes the four bulbs in that corner. Clicking an edge changes all on that edge. Clicking the center changes the center row and column.
You may decide to show the solution or hide it. The bulbs are numbered left to right, top to bottom.[less]
