Maze master Dave Phillips' latest series of distinctive configurations — based on the interlaced swirls and ornate symmetry of Celtic designs — is certain to challenge maze enthusiasts as much as it will delight the countless devotees of Celtic art.Puzzlists can test their skills with 36 tricky labyrinths. The goal is to find a way back to the starting point, moving through all designated points and passing each arrow in the appropriate direction. The series begins with the easiest puzzles and culminates with the most difficult, offering maze lovers at all skill levels challenges geared to their abilities. Just one important rule to remember, however: paths and intersections may be used only once! Those who lose their way in these convoluted constructions can take comfort in the fact that solutions appear at the end.
