HOW TO PLAY. To begin, click the "menu" button in the lower right corner. Then click the "start" button in the menu. This displays the Select a Puzzle screen.

The first time you play, you might want to select a smaller-sized circuit. So on the Select a Puzzle screen, click one of the rectangles in the first two rows to select a 5 X 7 circuit.

The puzzle is quickly built, and the bonus timer starts. To complete broken connections, click a gap in the circuit to rotate that segment. Detailed game instructions are below.

The goal is to complete the connections so that a continuous path exists from each light bulb to the square power source at the center of the puzzle. (The power source can be rotated also.) When you complete a connection, the bulbs light up.

More details from the online help:

"The object of Circuitry is to connect all of the bulbs to the power source. Click on the cubes to rotate them.

"Press the CTRL key and click a cube to lock it. Click the cube again to unlock it.

"From the Menu, press the Helper Walls button to place a helper wall. Each wall costs you 2 turns.

"Helper walls may or may not be very helpful. Many puzzles have multiple solutions. You may have a solution that crosses a helper wall.

"Rotate the remaining cubes to solve the puzzle. Your score is the minimum number of turns needed to solve the puzzle, divided by the number of turns you took."

This Circuitry puzzle game really forces you to concentrate and use your problem solving ability. An excellent brain game.
