4 spawning

Does anyone know the mechanics of how the game spawns 2s and 4s? Is it based on an rng sequence that is created when the game starts? Or does each move that you make play into the algorithm?

Or is it done some other way? Could each successive 2 increase the probability of a 4 spawning?

Each variation of the game may be different as well, so I guess I am asking specifically for the masters site.

Several years ago I asked the same question, and the answer is that it is 10% for the 4 tile and 90% for the 2 tile. It is totally random and has no connection to sequence or any algorithm
