Masyu (Pearl) - 400 Japanese puzzles

The goal is to draw a single continuous non-intersecting loop that properly passes through all circled cells. The loop must "enter" each cell it passes through from the center of one of its four sides and "exit" from a different side; all turns are therefore 90 degrees.

The two varieties of circle have differing requirements for how the loop must pass through them: White circles must be traveled straight through, but the loop must turn in the previous and/or next cell in its path. Black circles must be turned upon, but the loop must travel straight through the next and previous cells in its path.

The answers are given at the end of this book.
