A brain games book collects puzzles that exercise different skills. Sudoku is pure logic and deduction; word search trains scanning and focus. Look for graded difficulty so the puzzles keep up with you, and an answer key so you can check your work. Our printable packs cover both.

Forty word searches set in large, high-contrast type on a 13 by 13 grid: gardens, birds, baking, travel, music and more. Comfortable to read without squinting.
