Train Your Brain is an enjoyable way to exercise your brain and spend a few spare minutes during the day. While this collection of math and logic puzzles vary in depth and complexity, they are certainly challenging enough to keep anyone engaged. I found the structure of Grätzer’s book to be particularly appealing. … I really enjoyed solving and attempting to solve the puzzles presented in this book. … most could be solved by anyone from an advanced high school student to a college student with a solid background in mathematics. There is something for everyone in this book.
