Logic Masters Deutschland e.V.

Rules

• Normal sudoku rules apply.
• There are two invisible 1-cell-wide orthogonal paths (red and purple) in the sudoku:
  • They start and end at the dots (in their respective color) in the top left and bottom right corner.
  • The digits outside the grid indicate the maximum amount of cells in their column / row a red or purple path passes through, including the start and end.
  • Both paths may not overlap.
  • One of the two paths only allows prime numbers including 1. The other path only allows odd digits.
• Region Sum Lines: For each blue line in the grid, digits on the line have an equal sum N within each box it passes through (the sum may be different for each blue line).
• Cells connected by an X sum to 10.
