STRIMKO Puzzles

STRIMKO is a Sudoku-type logic puzzle created by The Grabarchuk Family. The main difference is that whereas in Sudoku every row, column and 3x3 square must contain different numbers, in STRIMKO every row, column and stream must contain different numbers. The grid size of STRIMKO varies, with the larger problems usually being harder to solve.
