Sorta an interesting thing I've stumbled over and been investing time into completing. the first 9 were easy, but i'm stuck on the 10th one. If anyone solves all 10 or even just the 10th one, let me know. That shit is hard.... I'm giving it a break now. Its the kind of game for those who have very good spacial perception, or far beyond normal mathematics and planes comprehension. Please if anyone solves the 10th one post screenshots of the 3 different views.
