Interested in the way things work, Rich Rollo enjoys working with patterns and all things math. His favorite hobbies include golf, bowling, Legos™ and Rokenbok™ (all of which involve keeping a score, using geometry, or small scale engineering.)
A math teacher by trade, Mr. Rollo always finds ways to keep his students interested and engaged in the topic at hand. The inventor of Number Cross Puzzles more than ten years ago, he has used the puzzles as an enjoyable warm-up exercise or extra credit in his classes over the years. It was really the enthusiasm of his math students that motivated Rich to finally get his puzzles published!
