Tectonic is a free and fun Sudoku game. It's an exciting game that's designed for all ages.
As a rule, adjacent boxes can never contain the same number. With tectonic you can challenge yourself with logic puzzles, and have fun all day long.
The principle is simple: all 1-cell zones must contain only a 1, 2-cell zones must contain a 1 and 2, and so on.
A number can never touch another number in any direction.
There is no time limit, so you can take as much time as you need to solve each puzzle.
You can play all 6 difficulty levels for free and improve as you play.
