Sudoku and board games are combined in Numberplace City. You are the president of a construction company that undertook the construction of an undersea city. We will build the buildings at the same time as our rivals, but we cannot build the same building in the same column, the same row, and the same block. After you have built the minimum number of buildings, you can use various effects. Some of the effects include taking the start player marker, spinning the board, or winning the game. Well, who is the best architect?
