Normal 6x6 Irregular Sudoku Rules apply, 4 times! The end result is a 12x12 grid divided into 4 6x6 grids by red lines. (See second image if needed)

Jigsaw Japanese Sums rules apply. Regions have been divided into puzzle pieces (dark edges separate regions). Colors outside the grid indicate the order of the runs of contiguous cells that must be shaded the color of the clue. The number in the square indicates the sum of the cells in the run. There must be at least one unshaded cell between runs of the same color, but that is not required for runs of different colors. All shaded runs are given.

Red lines separate the 4 6x6 sudokus. The pink line is a Renban line. Digits on it must be consecutive but not necessarily in order. Green lines are German Whisper. Digits on it must differ by at least 3.

Please notice the puzzle pieces are fish, boats and waves of water !
