Like Sudoku and KenKen, Strimko asks the puzzle-solver to complete a Latin square under certain constraints.
A Strimko puzzle consists of an N×N grid of cells, partitioned into N regions of N cells each; these regions are called "streams." The solver's goal is to fill each cell with a number from 1 to N, such that no row contains the same number twice; no column contains the same number twice; and no stream contains the same number twice.

Every Sudoku puzzle is a valid Strimko puzzle; a Sudoku is simply a Strimko in which the "streams" correspond to the nine subgrids. Puzzles equivalent to Strimko are often published under the name "Jigsaw Sudoku"; this name appears in print as early as 2008.<ref name="Moayeri2008">{{cite book |title=Diagonal Jigsaw Sudoku |author=M.
