Sujiken Puzzles

Sujiken puzzles are a unique and innovative type of logic puzzle that contains triangle-based grids, unlike traditional Sudoku, which uses a square grid. It is constructed from 45 cells placed in a right-triangle. The cells contain digit from 1 to 9. As with Sudoku, you must ensure no digit is repeated within a row, column or one of the three 3x3 larger squares.
