Mazer is a book that contains 27 different maze puzzles of varying complexity.In this edition, we introduce three major concepts in mazes. Type 1 mazes are traditional mazes where you travel in spaces from beginning to end. Type 2 mazes are the opposite in which you travel on the lines instead of in spaces. And the third type is a combination of both types. We also introduce a 3rd dimension to mazing with multiple page puzzles.
