Interesting puzzle game

This is an interesting puzzle game that I've stumbled upon. The object of the puzzle is to build a 3d object that meets the view requirements in the upper left corner. If you've found a solution, a green dot will appear next to the puzzle name. If you've found a solution using the least number of cubes, a yellow dot will appear next to the puzzle name. I've solved all of them (yellow dot) without cheating except the first.

It seems to give you a green dot even if you use fewer than the number they request.
I use 10 on figuur6 and it says to use 11.  So I get green because of that (though I could just add a block and get yellow).
I got yellow on all the rest.

Got all yellow, and same problem with Spiro, figuur6 doesn't seem to accept 10 as the minimum.
EDIT - figuur8 can be reduced to 12 too, instead of the suggested 16.

Hmm, I guess that the suggested cubes used isn't always the least number possible (although it should be).  Still kind of a cool concept though.

in figure6, when i use 11 i get green, when i use 10 i get yellow

Yea, I got a few greens too. I thought yellow was wrong till I looked up the solutions.
Interesting, kept my attention for a good 20 minutes.
There seems to be many mathmatic puzzle games on the site under the games section.
Please feel free to recommend them (the 4d puzzle cube is nice (double click on a square to rotate the face of the cube, abit like a Rubix cube)
