Divide the grid into regions, each consisting of nine orthogonally-connected cells. Every row, column, and region must contain the digits 1 to 9 once each. Digits along a pink line form a non-repeating consecutive set, but may be written in any order. A cell with a number in its top-left corner is a “Chess Sums” cell. The number in the top-left corner indicates the amount of Chess Sums satisfied by the digit in that cell. A digit in a Chess Sums cell gives one or more of the following: • The sum of all digits that share its region and are a king’s move away • The sum of all digits that share its region and are a knight’s move away • The sum of all digits that share its region and are a bishop’s move away
