perplexus.info :: Shapes : No Fault Coverage

No Fault Coverage (Posted on 2005-12-18)

Fifteen dominoes have been arranged in a 5x6 grid below. The '==' and '!' represent fault lines in the arrangement. A fault line is a straight line going all the way through the arrangement without hitting any of the dominoes.

Rearrange the dominoes so that there are no fault lines in the grid.
