The sudoku.coach campaign teaches you how to solve Sudokus step by step. The step-by-step solver can show you in detail how to solve a Sudoku. If you get stuck on a puzzle, the hint system gives you increasingly precise information on what to do next.
Hey folks,
I'm Jan, and three years ago I've quit my job to see whether I could make it on my own doing something that I love.
So for the past three years I have been developing the website sudoku.coach, which focuses on teaching the rules of Sudoku and all the different techniques.
Besides the campaign, which acts as a tutorial (teaching you everything you need to know about Sudoku), there is a solver which shows you how a Sudoku can be tackled step by step, a good hint system, a practice mode to help you spot more difficult patterns, and much more...
My hope is to be able to make a living out of it and improve the site more and more. The next big milestone will focus on Sudoku variants and connecting people (sharing their hand-set puzzles).
Cheers, Jan
