When I wrote Beautiful Abelian Sandpiles (https://eavan.blog/posts/beautiful-sandpiles.html) I wanted to show off some nice images of large identity sandpiles. But the simple algorithm I used was horrendously slow. Showing a sandpile identity that was larger than 100 by 100 took multiple seconds! That's not good enough! I became obsessed with trying to find a faster way, all in an effort to compute bigger and bigger sandpile identities, bigger than anything anyone had seen before. In the end, I did exactly that.
LegionMammal978 wanted to see a proper description of the identity calculation methods. You can consider this sequel to the initial blog post as an answer.

Reminds of the 2-player game named "Chain Reaction".
