Well, the author Robert Abbott is still making mazes and puzzles, though he's focusing more on board games these days. I discovered that many of his mazes are on his website Logic Mazes and provide some free entertainment for the maze enthusiast. (You have to be patient with his mazes. I had to solve several of them in roundabout ways. :))
Give your brain a workout. Click on the easy mazes and work your way up. It's an education in new ways of thinking.
