I previously created a combined slitherlink and sukoku puzzle, but I was unsatisfied because the grid was smaller then a regular sudoku. So I made another, larger one.
Below is a 9 by 9 grid. This is filled in with numbers based on the usual rules of sudoku. All of the numbers from 1 to 9 must appear in every row, column, and block.
A single, closed loop must also be drawn on the edges using the rules of slitherlink. The numbers describe how many edges adjacent to the square the loop passes through. Because a square only has 4 edges, the loop must use the number modulo 4. Numbers with a red background are liars. Liars are always incorrect, thus the loop must use a different number of edges. Since these rules are complicated, a table can be found below.
Sukoku number | slitherlink | slitherlink (red) |
---|---|---|
1 | 1 | 0,2,3 |
2 | 2 | 0,1,3 |
3 | 3 | 0,1,2 |
4 | 0 | 1,2,3 |
5 | 1 | 0,2,3 |
6 | 2 | 0,1,3 |
7 | 3 | 0,1,2 |
8 | 0 | 1,2,3 |
9 | 1 | 0,2,3 |
And also, the above grid has been converted into a more traditional slitherlink grid.
