I'll admit right off that my review is unfair. I've been a professional puzzle constructor for over 30 years. When I pay for a small collection of Hard-level sudoku, I'm expecting to see some tricky puzzles with dazzling designs. For example, this is a puzzle I made for Japan Airline (Brainbusters column).

+======+======+======+
|_1_____|_7_____|_2_____| .. These sorts of designs are hard to make, but they are
|_2_____|_3_____|_6_____| .. expected in top-level Japanese sudoku magazines.
|_3_____|_4_____|_8_____| .. With puzzlemasters like Naoki Inaba, it's a tough market.
+======+======+======+
|___4___|___9___|___7___| .. Red Hot has nothing like these. The patterns they
|___5___|___6___|___2___| .. use are very easy to construct, with lots of givens.
|___6___|___8___|___4___| .. In addition, I would rate these puzzles moderate at best.
+======+======+======+
|_____7_|_____5_|_____3_| .. However, their interface is pretty good. One of the best
|_____8_|_____2_|_____9_| .. I've seen on the Kindle for notes. Single-click, Fill.
|_____9_|_____1_|_____2_| .. Double-click, note. Works very nicely.

The boards at sudoko.com give all the tricks for become a master-level sudoku builder. The Puzzazz group should study there, or hire someone that knows all the tricks. For a truly master-level Sudoku book, try Mutant Sudoku.

Still, the interface is superb, so I'll give them the benefit of the doubt. The puzzles are better than most offerings.

The system used to input data is very convenient. Most of the puzzles are interesting. I find them easier to navigate and use than other publishers of Sudoku I have seen.

I have done several puzzles in Red Hot Sudoku 1, and found them to be challenging enough for me. Maybe they get harder as you move on to further puzzles, but that's OK.

Exactly what I expected it to be... I thoroughly enjoyed these challenging puzzles. In my spare time when I relaxed, I found them to be quite entertaining

The game format is very similar to Suduko Unbound but the puzzles are not truly hard... I was looking forward to some really challenging puzzles. Tsk! Tsk!

I like the program and the way it works electronically, but the puzzles are not very hard and I would like them to be more challenging.

It's easy to use and satisfying to work the puzzles. My favorite kind of pencil work with a challenge to solve.
