It's a draw .

[swannbaker]

With how few straight lines can you draw exactly 100 squares , no fewer , no more ?

[JoolsTwo]

I think 23? A grid of 10 x 10 squares? Probably wrong. :-)

[swannbaker]

Decidedly wrong .

[JoolsTwo]

Thought it might be. :-)

[eddiebun]

22 ?

[swannbaker]

Not 22 .

[eddiebun]

Of course, if you draw a 10 x 10 square, it contains many more than 100 squares, because there are 2X2, 3X3 squares too.

I still don't know the answer though !
