  Rules Normal Sudoku rules applied. Each cage is the record of n-th trick in a contract bridge game, where n is the number in the top left corner of the cage. 10, J, Q, K, A are recorded as 10, J, Q, K, A, but are treated as 12345 respectively when considering Sudoku rules. 2~9 are recorded as 2~9. For some cards, the suit of that card is given in the top right corner. Each cage contains the card played by West, North, East and South, from left to right or top to bottom. Dotted circles indicates the lead / first player of each trick. The up arrows indicate the cell must contain a J, Q, K, or A. The game result is recorded as 3NT/W +2, that is, No trump suits.

Clues outside the grid equals to the sum of the digits of cells along the indicated diagonal. Digits can repeat along these diagonals. One of the digits from 1~9 is Joker, when considering the clues of (3) and (4), the Joker never represents itself. E.g. if Joker is 1, it always means another digit in 2~9 instead. And Jokers can represent different digits in different equations. Digits in clues are also digits. So rules also apply to them unless otherwise specified. Links Penpa+
