How to play
What is Strimko?
Strimko is a logic number puzzle invented in 2008 by the Grabarchuk family. You fill an N×N grid with digits 1..N so that no row, column, or stream (a wavy region of N cells) repeats any digit. It's like a jigsaw Sudoku.
How do you play Strimko?
Click a cell to cycle through 1, 2, 3, ..., N (and back to empty). Each row must contain 1..N exactly once, each column must contain 1..N exactly once, and each stream (a wavy connected region) must contain 1..N exactly once. Press Enter to check, R to restart, H for a hint.
