Strimko is a logic grid & numbers puzzle and can be solved with a pure logic. The puzzle concept is very simple and 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.
Strimko 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.
You can play Strimko online but you can also download the logic puzzles. Happy Puzzling!
Update : There is also Strimko for iPhone
