3 and 4 could be reversed
that's true, you don't know for certain how many cubes are in piles 3 and 4, just that one has 2 and one has 6.
2 and 6 are not necessarily in this arder
I don't get it lol
iF THERE'S ONE BAD CUBES TEASER, I HAVEN'T HEARD IT!
This really shouldn't have such low fun, this is a great teaser...
since there are 20 cubes, the largest cant be 14 since half of that is an odd number.
if the largest is 12, half of that is 6. which will leave with 2 more cubes. so there will only be 3 piles.
if the largest is 10, half of that is an odd number.
if the largest is 8, half of that is an 4, which will leave with 8 more cubes. its elementary after that.

I think that if the teaser is edited and information is changed, then all comments referring to the original should be deleted. The answer has obviously been edited. i would much prefer a unique answer. For example, what sort of a teaser would this be. I think of a 3 digit number. All of the digits are square numbers.
Answer: 111, 114, 119, 411 , 419 .....
What's the point? If you you are going to give clues to find a number it should be unique!
