STRIMKO™, the popular web-based logical puzzle game, comes to the iPhone / iPod touch, so you can play on the move. Strimko is a number puzzle that introduces a new twist on the classic Latin Squares concept described by the famous Swiss mathematician Leonhard Euler (1707 - 1783) and popularised in forms such as Sudoku and similar number puzzles.

Strimko puzzles are all hand-crafted, tested and difficulty graded by experienced puzzle composers to provide a continuing challenge and attractive puzzle designs. Once you've played hand-crafted puzzles, you'll never want to play mass-produced computer-generated puzzles again.

Rules: Each row, column and stream (connected groups of circles) must contain only unique numbers (1 through to the puzzle dimension).

The rules are simple, but they give rise to a uniquely appealing logic for solving puzzles, and the possibilities for challenging puzzles are endless.


* 120 never before published, hand-crafted puzzles including 20 available to unlock
* 4 difficulty levels to cater for all experience levels: Easy, Medium, Hard and Master. The Master level is introduced for the first time.
* Puzzles in four sizes 4 x 4 through 7 x 7
* Choose between Original, Classic, Grayscale or Random skins to change the look of puzzles
* All puzzles are hand-crafted by humans for humans
* Each puzzle is solvable logically and has a unique solution
* Intelligent hinting system hints a space that can be logically deduced from the current position- no random hints that spoil the challenge
* At least 20 hours of challenging gameplay for all but the most skilled players
* Additional puzzle packs available
* Access to play and control music from your library from within the app (requires OS3.0 or above)
* OpenFeint integration for achievements, friends, forums/chat


Now also available is Strimko Gold: get all the content from Strimko and downloadable packs- over 300 puzzles in total. Plus you'll receive all puzzle packs that are released in the future as free updates. Strimko Gold is the best value way to access a ton of Strimko content.

Great entertainment!


Loved it! And I keep coming back for more. 👍👍

This is, by far, my favorite game. I recommend it to anyone. It is better than any sudoku game I've tried so far (more challenging). The authors did a great job. Too bad it is not updated anymore (with more games, retina display, iPad versions, etc.). Also, the spanish localization has some major spelling and grammar errors. Other than that, the game itself is extremely good!

So long and thanks for all the memories!


This app is about to disappear with iOS 11, since it had never been updated to 64-bit. So I finally finished all 189 puzzles while I still could.

Great game! I wish it had been updated and had even more puzzles, but it was a fantastic value.

Better than Sudokou!


If you like Sudoku, then you'll love this. These puzzles will test both your logic and observational skills. They are straightforward enough to learn on, and also have a hint feature if you get stuck. Giving it four stars for the apparent bugs in the Gold version that I wanted to purchase.
