how about something a little harder? this one is easy. you weight 6 on one side 6 on the other, which ever is the lightest you dump those 6 out then split the remaining 6 into 2 groups of 3, again look for the lightest and dump that one out. now your left with 3 so u measure 2 of the 3 if they r the same weight then you know the 3rd ball is the one or if one is heavier then the other then you know that way as well ;)
Yep, that's it. Now what if I were to tell you that there's more than one way? At least 5 more ways to do this. See if you can figure them out. (Your solution would be 6:3:1)

If you get bored, try 18 balls, using the scale again only 3 times.

And TZ, you can use put as many balls on any sides.
You could also do 2 on each side and do that 3 times.
