Pell Puzzles

A 6x6 grid must hold exactly eight paths with lengths 1 through 8, each connecting one X to one O, while the length-1 path simply marks an X. Paths may not touch themselves or form solid 2x2 blocks. Solve times feed a global leaderboard, and earlier puzzles are listed in a dated archive.
