Logic Masters Deutschland e.V.

RULE SET:

Normal Sudoku rules apply. Place the digits 1 through 9 in each row, column, and box.

RENBAN (PURPLE): Digits along a purple Renban line must be a set of consecutive non-repeating digits, and may appear in any order.

REGION SUM (BLUE): digits on a blue region sum line have an equal sum N within each box it passes through.

MODULO-3 LINES (GREY): Any set of three sequential cells along a grey Modulo-3 line must contain a complete set of residues Modulo-3: one digit from (1,4,7), one from (2,5,8), one from (3,6,9).

X-Pairs. Cells separated by a "X" must sum to 10. Not all X-pairs are given.

For our color blind friends:

Region Sum lines are really thick.
Renban lines are a medium thickness.
Modulo-3 lines are very thin.
