I love your site, thank you! I will be donating as soon as I set up a paypal account. You are correct, I pay a fortune for puzzle mags, this is worth the small donation and many, many more puzzles than in a mag. from the newsstand. Much appreciated!

Great site!

In addition to sudoku, there's another puzzle I like. Trigons, which could qualify as the new sudoku. In trigons, you have a pattern of intermeshed triangles. Each triangle has an inner number, which is the sum of the outer numbers.

Trigons are a staple in some of the Dell magazines. There are trigon books at, and trigon E-Books at

I've been hooked on sudoku for the past few months now but have moved onto something else. SHENDOKU is great because it can be played with 2 or more friends. Check it out at they've got some funny xmas cards too!

Back to the drawing board! My theory was that 9 givens would define a puzzle as long as all digits were used and there was one of them in each row, column, and box, but Tom Davis ( showed there were over a trillion possibilities in such cases.

I think your site is fantastic, and after addicting all my friends to this great puzzle, i have also forwarded your web site. Many thanks.

Bold, etc., claimed 24 givens are needed to solve a 9X9 puzzle, but another guy proved 17 are enough. Extrapolating from the 4X4 case, only 9 should be enough, but I think it would take a super computer to prove it.

Any thoughts?

2nd comment, because I didn't want to put a negative spin on the first one.

I do have to say that the ‘complaints’ shock me! I can understand asking you “in a nice way” if you had more Nonomino (because that’s what you “advertise”, huh??), or if it’s possible to print the answers, etc. but stating that you “should” do anything, come on people! Didn't you get here FREE just like I did?

How about a thank you for your time, bandwidth, etc?

I can't find the answers anywhere! Help the girl, somebody, please. I have searched every page for "Raw puzzle and answer" at the top of the page like it says in the FAQ?????

I'm good at puzzles, but obviously, I'm having a little difficulty following directions!!
