Sudoku Susser

Sudoku Susser is a free program that helps solve Sudoku puzzles. In addition to being more convenient than pencil-and-paper, the Susser also can show hints, solve the problem step-by-step using human deductive reasoning, or brute-force solve it using recursion. You can drag Sudoku problems directly from web pages, save, edit, print and more. And if you like the program, you can tip the author to encourage him to improve it.

What is new in this release:

• Bug fix in 2.5.6 caused paste of text puzzles to sometimes fail if a log panel had the focus; this has been fixed.
• Relaxed a restriction in the Consequence Trees hilighters that caused it to sometimes miss contradictions that had a common "trunk" path. While it's arguable that this restriction is reasonable (and I'll argue it, damn it!), it's pedantic, unhelpful to the user, and sometimes caused the hilighter to report a verity that, while it had correct implications (and wouldn't steer you wrong), wasn't a "real" verity. Kudos to Setemkia (Fawn) Falling Tree for noticing this.

Requirements:

Mac OS X 10.2.8 or higher
