Difficulty: Hard

Discover a focused and rewarding puzzle experience with the Tree of Life Edition of this long-division cryptarithm book. Every puzzle in this collection uses only long-division formatting combined with letter-to-digit substitution. There are no addition, subtraction, multiplication, or cross-figure cryptarithms. This book is dedicated entirely to long-division cryptarithm logic problems for solvers who want a consistent and specialized challenge.

The book is organized into four main categories. The first category introduces the Domain level of the Tree of Life. The remaining three categories are devoted to the individual Domains: Bacteria, Archaea, and Eukarya. Each group contains its own set of hidden phrases and its own style of challenge, giving the collection a clear structure that progresses from broad biological concepts to more specific branches of life.
