About

Hello! My name is Joel A. Fletcher, inventor of the patented “Mathematical Puzzle Game System and Method.” I call my new game DIAGNUMB 1 Math, designed for teens and adults. DIAGNUMB puzzles use subtraction between single-digit numbers and deductive reasoning (The process of elimination) between multiple-choice answers to solve, and are timed-based (optional) to rank your score to win. Each book contains a practice puzzle and 30 increasingly challenging new puzzles with solutions.
