The path must change direction at every roundabout, and it must also change direction exactly once in the intervening squares between roundabouts.
A Domino puzzle consists of a rectangular grid, with each cell of the grid occupied by a single digit number. The grid represents a pair of domino pieces laid out in a rectangular array. To solve such a puzzle, it is necessary to outline pairs of adjacent numbers in such a way that every piece of the domino pair is revealed.Study the puzzle until you discover an adjacent pair of cells which you believe represent a domino piece. Then point the mouse cursor to approximately the mid-point of the line separating the pair of cells, and click the mouse. This will remove the line. If you make an error, another mouse click in the same location will restore the line.
