NrGrudge is a 2 player board game. When it is your turn, you move one of the digits into an empty field of the board. When all fields are filled, the game is over.

At the end of the game, for each row the values in the fields are added and the result is compared to the "task" for that row. Based on this, you earn points for the row. The same for the columns. A players score is the sum of the earned points for all rows and columns. The player with the highest score wins.

Because each player has different "tasks" for the rows and columns, each player has a different score. And each player will have a different strategy to place the digits.
