Nice puzzle, but done entirely on guesswork :L.

I must have guessed wrong :(

Don't forget to try the puzzle before posting it. Thanks, Elowen!

Yep...had to guess the entire time, but I got it right the first time I tried to validate! Pretty easy even if it isn't really logical! Thanks! ~:)

SPOILER ALERT!!!!
If you are having problems, keep in mind that its two "circles"...one inside the other. On the OUTSIDE of the circles the squares will be placed in an "X" pattern (but they are only on the OUTSIDE of the circles. They do not continue in the middle of the puzzle!) Hope that helps a bit!!

When i get a perfect solution..why does it say invalid ????
there may be more than one solution, that does not make mine wrong !!!

@fabs2012: I am not sure if you are new (so if you aren't just disregard this message)...
The puzzles are created by all of us (anyone can make one). You have to match the design made by your fellow players EXACTLY to get a "valid" answer. There have been MANY times when I have had a "perfect solution" on many puzzles as well. You just have to keep trying different "perfect solutions" before you get the EXACTLY correct answer.

I hope that helps explain things! ~:)

Managed it first time but was pretty much guesswork. went off cross-referencing the "2"s where they cross over.

It doesn't need guess work. since it is symmetric, all of "2" can be placed in cells 5 and 6 of the rows and columns.

Thanks.

Saeed, you are very incorrect--while the 2s can be placed by symmetry, several of the 1s can be placed in different patterns that still observe symmetry.
