Beta Books: What do I get?


Engage your analytical side with these numerical brain teasers. Math and logic puzzles help you stretch your mind to think in new ways. They flex your lateral thinking as you work through fresh problem styles. Each puzzle type comes with an explanation, a method for solving them, and solutions if you get stuck.

The puzzles in this book are short, self-contained, and “gritty.” They offer an enjoyable challenge and are designed to be solvable within a few minutes. You only need basic arithmetic to solve these puzzles; no advanced math required. There’s plenty of variety to keep things fresh. From wandering digits to magic triangles, from summing grids to water pails, you’ll find something that catches your interest. Each puzzle is brief, so use them as a warm-up to your daily work, for a delightful diversion on your coffee break, or solve a few while you wind down for the day.

Grab a pencil and your thinking cap, and get solving!

What You Need

To get the most from these puzzles, you’ll only need your mind, and maybe a pencil and paper. Bring along a colleague, friend or a child to share the fun!
