http://www.cubelagoon.com/?ref=1285 Basically, you answer surveys to gain points and then use those points to claim prizes. Such as a rubiks cube. Its 100% free. I've gotten a 3x3 white cube and a 4x4 rubiks cube from here. Its very fast. For a 2x2 cube, its 4.75 points and each survey is around 0.5-2 points. So you can get it in no time. Just use that link and sign up and start answering surveys.
On a 3x3 there are 9, 4x4 there are 16 and so on. Basically whatever number of squares on one row going across times that number.
Plastic.
