basketball!

I guessed it :D.

I also guessed. Lol. It's pretty simple guessing tho. ;)

I find it not easy to guess ...
it is not 100% to solve logical.

Hint: the 3's in r1 and in c25 form the edges of circles, one forms a basketball, the other forms a head.

I wish I could rate this 0.

Hint for the remaining 1s--most of them form two diagonal lines from the "arms".
