Thanks for a top-level overview. I have no practical experience with 
game /programming /, just some general concepts which I offer here, and 
leave it to others to assist.

You might add more specifics - do you want a graphics display? User 
interaction? Anything you add to your description helps us and helps you 
move to your goal.

I suggest you start simple, get something working then add another feature.

Simple? Could be as simple as 1 grain falling till it hits bottom. Does 
it have an initial velocity? Does it accelerate under the pull of 
gravity? Velocity means speed and direction. What happens when it hits 
bottom?

Then add a 2nd grain. What happens if the 2 collide?

What is your update rate (how often do you recompute the positions of 
all the grains)? What is the smallest increment of position change?

I assume you will create a class for each type of sand grain. with 
relevant properties and methods.

You will need a program that runs in a loop (probably with a sleep) to
-  update positions and  velocities of each grain (by invoking class 
methods)
-  detect and manage collisions
-  display each grain (by invoking class methods)

If you are using a graphics package I assume you will have a "canvas" on 
which you will draw some kind of object to represent a particular class 
of grain at the current x,y(,z?) coordinates of each grain.

It is possible to change the base class of an object on-the-fly, so a 
lava drop could become a sand grain.

That's all for now. Good coding!

I don't want to copy the game

Is there a Python version out there?
