Tectonic Solver (Kemaru / Suguru) with Step by Step - Online Resolver (2024)

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.

Example:

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.

Sometimes the reasoning reaches a dead end where no immediate logical deduction can be made, leaving several possible values for a cell. In such situations, the solver analyzes the boxes with the fewest possibilities and chooses a value that it believes to be the most likely. If it encounters an inconsistency (i.e. if the grid no longer has a solution), it returns to the selection step and tries another value. To maximize the chances of success, the selection is not random; the choice is made by favoring a value which, once placed in the cell, will allow the maximum number of deductions in the rest of the tectonic. This approach is the fastest for the solver, although it may sometimes be possible to obtain the same result by a more complex and slower deduction.

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.
