I'm just thinking that if the game do not stop at 2048 it will be much more challenging, as reaching 2048 is a relatively easy task for AI.

It shocks me that the magenta is not on the physical spectrum. It means that there is no such a frequency that produce the color magenta.

Slightly more common example of "colors" that doesn't exist in spectrum are white, all shades of gray, and black :)

Brown is another strange color.

Check my AI for 2048 https://news.ycombinator.com/item?id=7474909

Only reach 8192, but with the game implemented in the right way :)

I must say that the game itself is implemented in the wrong way! The AI here is just playing another much simpler game here.
