About the book
Train Tracks on paper, away from the screen: 400 grids that climb from gentle 6×6 warm-ups to 12×12 expert routes, including closed-loop variations. Every puzzle has one solution you can reach by logic alone.
The numbers tell you how much track runs through every row and column. Your job is to find the one railway that fits them all. No maths and no trivia, just clean logic.
The book has two styles. Station-to-Station Routes run between two marked stations on the edge of the grid. Closed Loops have no start and no finish: one unbroken circuit that returns to where it began. Each level is graded by the solving technique it needs, not just by grid size, so every step up teaches something new.
Who it’s for
Sudoku and crossword fans who want a new kind of logic puzzle, beginners who want a gentle start, and experienced solvers looking for a real 12×12 challenge.
