Triangles Sudoku is a fascinating Sudoku variation that introduces a unique mathematical constraint to the classic Sudoku puzzle. Along with the standard Sudoku rules, the sum of the digits at the three vertices of every triangle must be the same throughout the entire grid. Although the common sum is not given, it can be discovered gradually by using logical deductions and the relationships between the triangles. This additional rule creates an enjoyable challenge for Sudoku lovers.
The puzzle first appeared in the World Sudoku Championship 2009, where it attracted the attention of many Sudoku enthusiasts. This handcrafted puzzle was originally created for the Indian team's practice sessions and is now republished as part of the Fun With Sudoku series.
