Wisdom Effect Benchmarks
Puzzle book benchmarks
We test what makes a puzzle book good, such as how consistent its difficulty levels are, and publish the raw files so you can check every number.
All benchmarks
How we test
Independent rating
We rate puzzles with outside tools, such as Sudoku Coach, not with our own engine.
Raw files to check
Every benchmark links the PDFs we tested and every puzzle, so you can repeat it.
Open to corrections
We compete with some products we test. Found a mistake? Write to info@wisdomeffectapp.com.
