Driven Sudoku is a traditional Sudoku playable directly on all the e-book reader!
Playing it on a newspaper (or with a Sudoku app) Sudoku is an "open" game where the solver can choose both the cell in which he wants to put a digit that the digit itself.
On the e-readers, Driven Sudoku is the best solution for playing Sudoku, especially on the e-ink devices, but not only these.
Simply, limiting the possibilities of one "input cell" at a time, you can choose the digit for this cell, and if the digit is correct, the game moves to the next grid "updated" placed on another page, in where you will find the added number and a new "input cell" is proposed, and so on, until the grid is completed and Sudoku will be solved.
Note that in this process, every digit is always logically solvable using the other digits in the grid. But, if the inserted digit is not correct, the game jump to the "error page", where you can choose if retry or go on.
I hope everybody will enjoy with our Driven Sudoku!
