To illustrate a valid solution, here is a first non-optimized at all solution of value 79
Let us fill a Peaceful Weighted Sudoku Grid with as many value thanks to Chess pieces with the following rules:
- There must be a Black King in the grid not checkmated
- There must be a White King in the grid not checkmated
- There must be at least one Black Queen
- There must be at least one White Queen
- There must be at least two Black Rocks, Bishops and Knights
- There must be at least two White, Rocky, Bishops and Knights
- There must be at least 8 Black Pawns and 8 White Pawns
For each row, each column, each diagonal and each box:
- There must be at most one Black Queen
- There must be at most one White Queen
For each row, column and each box:
- There must be at most 1 Black Rock
- There must be at most 1 White Rock
- There must be at most 1 Black Knight
- There must be at most 1 White Knight
- There must be at most 1 Black Bishop
- There must be at most 1 White Bishop
- There must be at least 1 Empty square
- There must be at least 1 Black Pawns (and at most 8 Black Pawns)
- There must be at least 1 White Pawns (and at most 8 White Pawns)
For each diagonal:
- There must be at least 1 Empty square
- There must be at most 1 Black Bishop
- There must be at most 1 White Bishop
Everytime a Queen appears you score 8 points
Everytime a Rock appears you score 5 points
Everytime a Bishop appears you score 3.3 points
Everytime a Knight appears you score 2.7 points
Everytime a Pawn appears you score 1 point
What is the maximum score you are reaching? :D
Notes: there is no promotions for the pawns and you choose whether Blacks attack towards the north or if it is Whites :)
