Q: Whoa, $2.99 is expensive! Why are you charging so much?
A: On Amazon I see books of puzzles for more than $3. Those books have at most a few hundred puzzles. This Sudoku game will generate hundreds of thousands of unique puzzles. There is always this answer too: The Oatmeal (read it for a good laugh, even if you are not convinced).
Q: How are you generating the puzzles?
A: I'm using an algorithm called "Dancing Links". The puzzles are generated right in your browser.
Q: How did you implement that?
A: I used an excellent application framework called Sproutcore.
Q: Are you going to add new features?
A: I hope to, for sure. I am always looking for constructive feedback so I can improve the sudoku playing experience.
Q: Will I have to pay for new features?
A: I don't plan on double charging my customers. If I add significantly complex behavior, like sending puzzles to friends, forming groups, social networking integration, I might raise the price, but if you bought it you won't have to worry.
