From the incredibly talented Grabarchuk family (Untouchable 11 , Four Rings) we have a brand new logic game called Strimko. The object of the puzzle is to fill in the missing numbers, keeping in mind these simple rules:

• each row must contain different numbers
• each column must contain different numbers
• each stream must contain different numbers

Every month we’ll be posting a new set of Strimko challenges hand-made by the Grabarchuks especially for Smartkit. This month we have 3: easy, medium, and hard.

I’m sure Peter, his brother and Dad would love to hear any feedback, so please feel free to post in the comments section below. Thanks! -RK
