(PART 1) Frequency Disappearing Ink: 200 Math Puzzles to Train Your Brain Linked PDF

Love Frequency puzzles? Get ready for a clever new twist!

The first of the Disappearing Ink series, this book ups the challenge from the classic Frequency puzzles you love. Part 1 of this book is packed with 100 handcrafted 4x4 puzzle grids and well, it got pretty tedious to input all those numbers, so I may have left some out….you’ll be fine, right?

Use addition, pattern recognition, and number logic to uncover the unique solution to each handmade puzzle. These manageable grid sizes limit the mental math load while increasing the logical difficulty of the puzzle, perfect for keeping the mind sharp.

Disappearing Ink is a clever workout for the puzzling mind.

Why puzzlers love this book:

• 100 4x4 grids with room for notes
• Progression of difficulty from novice to existential
• Reference tables of number combinations included to aid your logic
• Full solutions in the back of the book
• New and seasoned-puzzler friendly!
