How to play a Tectonic ® puzzle?

When playing a tectonic puzzle, just like with sudoku, you may enter a limited number of numbers.

Whereas in sudoku the numbers 1 to 9 are the standard numbers, in tectonic puzzles these numbers depend on the number of boxes a block is made up of. The tectonic puzzle is made up of blocks of different sizes, from one to five boxes.

The aim is to fill in the tectonic puzzle in such a way that adjacent boxes never contain the same numbers. Not even diagonally. Adjacent boxes must therefore contain a different number.
