All Strimko puzzles are solvable with pure logic; no special knowledge is required. Strimko uses only three basic elements: rows, columns, and streams. All elements have an equal number of cells, and the goal is to make each row, column, and stream contain the whole set of specified numbers. Cells in the grid are organized into several streams of equal length, which often run diagonally and even branching. Such mechanics create entangled patterns resulting in interesting challenges and unusual logic.

Strimko challenges were handcrafted by Helen, Tanya, and Peter Grabarchuk, and hundreds of original Strimko puzzles were published in various forms and platforms: Web, iOS, PC/Mac, Kindle, paperback.

Overview

Rule #1 Each row must contain different numbers.

Rule #2 Each column must contain different numbers.

Rule #3 Each stream must contain different numbers.
