3. At the very top of the page it says "solve two related puzzles".
11. Words can be read in any of the 4 directions, as in the example.
10. The standard rule for the loop: Loop does not touch or intersect itself. In the example, the V pentomino is used twice. In this sense, it is possible to repeat. But there is no third V pentomino among the 14 given pentominoes. Therefore, you cannot use the V pentomino three times.
