Opposite sides a die add up to 7, so from the first angle we can see 1 facing right, give 2 right facing rotations of π/2 (90 degrees) which is 1/2 a full rotation. Meaning the opposite side of 1, 6 is now facing right. The forward rotations towards the screen don't rotate the right 6 side but do rotate 4 on top to 3 on top which was the original top side configuration only now with a 6 right side. After that we rotate the die again by this time 3π/2 (270 degrees) or 2/3 a full rotation. The right facing side 6, becomes the bottom side then the left side then finally the top side, making it 6.

I own dice that are not like this. They come in three kinds:
1. D3s have the same number on opposite faces.
2. Turn-taking dice are matched sets where no two dice can roll the same number. These count far beyond six.
3. Cheap dice from China are sometimes just made by people who don't know how normal dice are supposed to be.

A valid exercise can't assume such common things don't exist. Are you sure your shoes are tied?

Since acc. to the author we can assume that opposite faces add to 7, the really easy way is to realize that rolling twice forward gives the (7-n) forward-facing face, rolling sideways does nothing, so on the square before last (7-(7-1))=1 is forward facing and lands on the last square.
This would also make more complicated paths easier by "cancelling" even numbers of rotations and only having to track the odd ones in your head.

you can label the other sides as the inverse of the one you can see. there are three sides. call them a, b, c, such that a = 1 , b = 2, c =3. then, a^-1, b^-1, c^-1 represent the values on the opposite side. You can proceed with the problem.

you can make a function f which denotes one procession or flip of the die in the 1,3 axis and a function g which denotes one procession or flip of the die on the 2, 3 axis.

so if the initial state is f(0), then

f(0) = 3
f(1) = a^-1
f(2) = c^-1
f(3) = 1
f(4) = 3

and so we see that f(x) is some value x mod 3

additionally,
we set
g(0)=3
g(1)=b^-1
g(2)=c^-1
g(3)=2

so now we simply count the flips

our function is

f(2), g(2), f(3)

These operations are commutative, so first we take f(5mod 3) = f(2) = c^-1 = g(2)

So now we have
g(2), g(2), which is the same as g(4 mod 3) = g(0), which is 3.

So, this dice rolling on a track is idempotent.

Therefore, we have shown that the number on top will be 3.
