I remember that I needed 2 minutes to find the first two, and more than 10 minutes to find the 3rd. It's a good one!
Lol, I am not that quick

Took me about 1 minute to find the first one,

about 30 minutes to find the second one because it requires an odd way of thinking imo

and I don't even see how a third solution is possible, although I am sure there is one ( and possibly more ).
