Teaching you the ways of Sudoku, for beginners & improvers. BUT no Numbers !!
About Letter Sudoku
Letter Sudoku is a new take on the classic puzzle, for those that don't like numbers !
As Sudoku is a pure logic puzzle, there's no need for numbers at all, so here we use letters instead.
Letter Sudoku also uses the same techniques as our sister app "Sudoku Teacher." It's a new way to learn Sudoku. Instead of being based on ways the computer can solve a puzzle, Sudoku Teacher takes you through the methods a human would solve the puzzle with pencil and paper.
Letter Sudoku uses long established techniques of classroom learning to make sure you learn at your own pace and in your own way. You are not under pressure to learn with "rewards and levels", you can take it at your own pace and chose how much assistance you want.
Letter Sudoku does display small ads, to help us to get back some of the cost of development. You can get rid of these ads for ever by payment of a small fee. But if you are happy with a few ads at the bottom of the screen, the app is free to use for as long as you want.
