Currently, for this week I am publishing puzzles for Mini Sudoku Series. Thropki Sudoku is part of the Triplets and Triangles LMI Sudoku Test which is going to happen coming weekend. I thought to create a couple of Sudoku of this type and I am uploading this Sudoku so that readers of this blog who want to participate in this test can have something for practice as this Thropki Sudoku type is a new Sudoku variation and nothing much is available for Thropki Sudoku anywhere.
Now coming to the name of the Sudoku. It is called Thropki Sudoku. This Sudoku is similar to Kropki Sudoku in looks may be the reason for this Sudoku being named Thropki Sudoku. Thropki also suggests something related to the number three which forms the core part of this Sudoku. This is the fun Sudoku and one hopes that one will get good practice for the Triplets and Triangles LMI Sudoku test.
This Thropki Sudoku, I am posting in the Fun With Sudoku Series as the 180th puzzle in this series. Can you solve this Thropki Sudoku puzzle?
