Mine finder logic puzzle books for Amazon KDP & Etsy

A logic puzzle on a grid of squares. Some squares show a number: how many of the up to eight squares around it hide a mine. Using only those numbers, the solver marks every mine. Numbered squares never hold a mine, and a good puzzle can be finished without a single guess.

No. The generator solves every grid with the same steps a person uses — a number whose mines are all found or all placed, the difference between two neighboring numbers, and chains of overlapping groups — and rejects any grid where that logic stops before every mine is known. There is never a 50/50 choice.

The logic each level needs. Easy puzzles are solved with direct deductions from one number at a time. Medium adds set subtraction: comparing two numbers whose neighbors overlap. Hard needs chains of such subsets, and keeps fewer numbers in the grid. Bigger grids and more mines make each level longer.

Each puzzle gets a score from 1 to 100: the longest chain of steps the solver needs (45%), how many subset steps it uses (35%) and the share of mines (20%). It lets you sort a book from gentle to tough and can print under each grid ("Difficulty 42/100").
