First - what is a Solver Behaviour?
Think of it as a silent observer that watches your game with an intent to modify the cube to a Pattern it desires. In between turns, The solver will rotate the cube so long as neither player are in check/mate.This is optional. Don't freak out!

Here are the 2 we have so far:

Normal
this solver is self explanatory. The solver will rotate the cube on the shortest path to a completely solved cube.

Undo
Similar to Normal except this Solver solves the cube by Undoing all moves made by players! A subtle but important difference.

Checkered and Stripe patterns are next but first we'll see how these do for now! Once again, these are optional. Don't freak out!

As for the UI:

After:

Again, sorry for the delay, hope to see you all soon!

P.S. Beta testers... good luck.
