Rules:
Normal Sudoku rules apply. Two arrows of the same colour pointing toward one another in a row, a column or a diagonal indicate the presence of a sandwich. The cells containing the arrows are the boundaries of the sandwich and these cells are also the digits of the sum of all the cells between these boundaries, in any order. A cell can be a boundary for several sandwiches in the same line. Digits may repeat in diagonal sandwiches.

PLEASE CHECK OUT THE EXAMPLE AT THIS LINK IF YOU ARE UNSURE ABOUT THE RULE SET ABOVE!

There will be one orthogonally connected 13-cell region for each suit, plus 2 Joker cells that are not in a region.
