Sudoku Susser for Macintosh

A comprehensive Sudoku assistant and master-level solver. Hints mode shows you what numbers are legal for the remaining squares.

The Deducer uses human-style reasoning to solve the puzzles and can take you step-by-step through their solution with detailed explanations of each step. The brute-force Recurse option solves all puzzles. And tons of hilighting modes help you see the patterns in the puzzles. You can even drag puzzles right off the Web pages of major UK newspapers into the application, then edit, save and print them for offline fun. Puzzle list now stores the complete state of the puzzle, not just the initial squares. If you partially solve a puzzle and add it to the puzzles list, when you reload it, it will be perfectly restored (all non-initial solved squares with black digits, all partially reduced squares partially reduced).
Version 2.0.3 may include unspecified updates, enhancements, or bug fixes.
