Hints




Click a Tab to reveal the Hint.

You need to move a pair of blocks in one single swap. First, take a look at how all of the wires are connected.

Find the wires connecting the monitoring device (upper right) to the prime minister's heart sensor (lower left).

Take note that the two wires leading from the pocket watch in the lower-right corner connect in the middle. Pay close attention to this path.

Have you noticed that only certain blocks can be swapped with each other and still connect? Keep an eye out for blocks that have matching wire entry and exit points.

The two blocks are both in the third row. Look carefully.


Solution

Incorrect

Too bad!

Remember, you only need to swap one pair of blocks.

Are you sure you didn't move more than two?

Correct

Amazing!

You successfully swapped the devices!
