pure logic

Wow!!! That is an incredible puzzle! Avoid guessing on this one because logic really is possible. How long did this take to create?

Plus chances are you'll guess wrong!

Now THAT'S what I'm talkin' about! GREAT puzzle! I wish they had an 11 rating!

Excellent. Can be solved without guessing.

Great puzzle. Really enjoyed that - thanks!

Very nice puzzle.

A perfect example of a completely logical puzzle that doesn't have to be full of black squares! Excellent 10/10 :D.

Really enjoyed it :)

Brillant puzzle, really enjoyed it x.

This is a very good puzzle. It really made my brain work.

It took 19 1/2 minutes... and if it wasn't for everyone saying it could be done, i would of given up. but surprisingly, it is completely do-able with just pure logic :)

Absolutely lovely!!

Excellent!

Thank you.
