4872 first game. I got all the pieces on every level except the first because I didn't realize you could. Pretty fun and I don't even play chess. Are the levels designed by hand or generated?
They must be generated. Hand designed levels probably wouldn't have things like pawns on the first rank, or four opposing rooks, or situations where the first move unavoidably loses points.
I had a similar thought, randomly generated in 'strength'/points and positions. Pawns on first row are impossible, and last row turn to Queens (or whatever).
There must be a 'relative position' though in the mix of the algorithm, because on some levels the pieces are scattered in the four corners and some others they are on 'perfect-knight-stepping-sequence' so I could take 5-6 pieces in 5-6 moves and then exit.
Levels are generated randomly. The number of black pieces grows until level 10, then randomly fluctuates.
