How to Solve a Stardoku Puzzle

Each puzzle follows the basic rules of Sudoku: the numbers 1 through 9 must appear once (and once only) in both diagonal columns, each horizontal row, and each large 9-segmented triangle. Note that outside diagonal columns and outside horizontal rows will include each associated "tip" triangle (see example image). Each puzzle has only one unique solution, and each can be solved using pure logic. Good luck!
