Tectonic is a straight brain teaser.
Michael Dijkhuizen
It’s a bit like sudoku. When you open a game for the first time, how it works for new players is somewhat unclear. Request instructions in Dutch via the menu. The number puzzle is divided into a number of zones. For example, if such a zone has four cells, you must enter the numbers one to four. Identical digits from different zones may not be adjacent horizontally, vertically and diagonally. That makes solving a so-called tectonic puzzle quite difficult.
Operation is simple. Tap a box first, then tap the target number at the bottom. If requested, the app shows the solution of the selected field via the light at the bottom.
Tectonic contains thousands of puzzles. Some are free, but most puzzles are paid for with credits. With a free account and registration for the newsletter you will receive five hundred. You can also buy additional credits at any time.
