4.2. Stack to Stack Moves
- To test the initial versions I generated a 1000 test boards.
- I noticed some of them were not solvable.
- I played some of them manually, and noticed they were solvable using a move that I missed.
- The latter was a meta-move that placed a card on a parent card on the same stack
- By implementing it, all of my boards turned out to be solvable.
