I always find it gratifying when I finally solve a Tridoku puzzle. I felt thrilled when I solved this Tridoku puzzle.

How to play Tridoku: Tridoku consists of nine large triangles. The numbers 1-9 must be placed into the triangular cells of each large triangle. The numbers 1-9 must also be placed in the three legs of the inner shaded triangle and in the three legs of the outer shaded triangle. No two neighboring cells may contain the same number.
