Lets see if you get this right.

I didn't see all the lines lol. It's 3 but you need to turn the tap on first :)

The numbers are wrong then...not MY fault.

LOL...oh I see!!! Okay 3. Tricky little puzzle... 🤔

I don't trust the question. :)

Yup, it's 3 4 is closed, and 3 is shorter than 2, and cup # 2 needs needs to fill 2 cups while cup #3 neds to fill only one.

As in everything in life you need to thoroughly check the details..

I am guessing since water flows downhill?

It would depend on the speed of flow of the water but not if those blocks are there.
If it were very rapid then 1 would fill first.

I think we mostly miss seeing those because we're focusing on solving (ignoring blocks) and not on all that is there.

So, it's a clever question showing how we need to read/look carefully.

Okay i got it now its 5
Nope not 5 eaither.

Oh it's 3

1, 2, and 3 may never get filled depending on the flow rate.

None, you have to turn the spigot on first ?

5 and 7
