Customer Reviews

Great Elecronic Version
I did a lot of research before buying an electronic version and this game and this one seems to be the best one. Other than no backlight, which I don't really care about anyway, this one is great. The game is all controlled with the stylus. Just touch the empty slot with the stylus and touch the number you want in the slot. It's that simple. It has three levels of play with an endless supply of computer generated puzzles. It even has 400 pregenerated unique puzzles. And an added bonus is that you can take a puzzle from a newspaper or some other source and enter it into the game to solve electronically.

Adept
This particular unit has been around awhile (I also have one from London branded "number puzzle"), now rebranded by Franklin for an American release.

First, there is no backlight.
Second, some of the puzzles end where two answers are both correct, which drives some Sudoku purists nuts.

But these are the Only drawbacks.
The unit fits well in the hand, and is easy to use. You can put in your own puzzles, pause, Undo, and toggle sound.

I cannot imagine having a Sudoku handheld game whose screen isn't fully a touchpad, and which doesn't have the ability to put in puzzles from your favorite source! And I can't imagine I'm the only one either!

Non-unique solutions; no pencil marks
Nice size, good mode of entry. However, I have two complaints. The first is that some of the generated puzzles have non-unique solutions, which means that logic takes a back seat to guessing. The second is that there's no provision for pencil marks. Pencil marks are the ability to keep track of which numbers have been eliminated from a square. For example, the downloadable Sudoku games available for the Palm system offer this--you enter the available numbers, which appear in smaller font, arranged 3 X 3 in each square, and delete each number as you logically eliminate it.

Looking at the hardware, I can see why they don't offer pencil marks: each box is a 7-segment LCD, so it can only display full sized numbers. The Palm screen, on the other hand, is bit mapped to about 320 X 320 (depending upon your model) and can display many different fonts in many different sizes.

My wife says my dogs bought it for me for Father's Day. I think she helped them wrap it, however.
