Tectonic Solver

Tectonic (also called Kemaru or Suguru) is a digital logic game where the user fills a grid with numbers. Tectonic is played on a grid divided into regions of 1 to N squares that the player must fill in with numbers.

A Tectonic grid follows 2 rules: each block must contain the numbers 1 to N (without repeating numbers) and each cell must be different from its neighbors (including diagonally).

Indicate the known figures, and trace the outlines of the regions/blocks. It is possible to copy and paste and/or note directly in the boxes.

The program approaches the resolution of a Tectonic in a similar way to a human, evaluating the possibilities in each box and making deductions.

— Only possible value: this cell can only contain this specific value, other values do not respect the rules.

— Only possible cell: this value cannot be present in the other boxes of the block or region.

With each cell or number validation, the solver exposes an additional step in its progress for better understanding.

The best strategy is one that narrows down the number of possibilities and helps fill in the boxes with numbers. Some tips:

— Identify the regions of the grid, especially the small regions of one or two squares for which the numbers are obvious.

— Start with regions and boxes with neighbors with many numbers already placed.

In a Tectonic, the grid presents regions sometimes called blocks (or groups, or sectors or sub-grids).
