The Strimko Logic Puzzle

Strimko is a logic puzzle with numbers. It is based on a well-known idea of Latin squares described by a famous Swiss mathematician and physicist Leonhard Euler (1707-1783) in the 18th century. In a Latin Square in each row and each column only different numbers from a predetermined set are presented.

Strimko has the following features.

1. Strimko is a logic grid & numbers puzzle. All challenges are solvable with a pure logic, and no special knowledge is required.

2. It is a very simple puzzle concept which uses only three basic elements: rows, columns, and streams. All elements have equal numbers of cells, and the goal is to make each basic element containing the whole(!) set of specified numbers. The main feature is that in Strimko all grid cells are organized into several streams of equal length, and mostly Strimko grids contain streams running diagonally (partly or fully) and even branching. It creates quite incredible and entangled patterns resulting in amazingly interesting challenges with winding and unexpected logic, and thrilling impression.

3. Challenges are quite compact (4 x 4, 5 x 5, 6 x 6, or 7 x 7 grids), so the solver uses a small amount of numbers. Of course, it can be extended over 7 x 7 grids, but there is no special reason for that, since even within 5 x 5 and 6 x 6 grids there is a huge number of hard and extra-hard challenges. To make a challenge logically solvable, in many cases even a minimal number of clues can be enough: 3 clues for 4 x 4 grids; 4 clues for 5 x 5 grids; 5 clues for 6 x 6 grids; 6 clues for 7 x 7 grids; and so on. This is another unique feature of Strimko.
