Hi Robert, thank you for your solution;
it is an easy puzzle, 38 clues not minimal that i solved with a short forcing chain:
- Code: Select all
5r26c9 => r3c4 <> 5
r2c9=5 - b1n5{r2c12 r3c2}
r6c9=5 - b5n5{r6c56 r5c4}
ste.
with templates initializing it is enough to find its solution:
- Code: Select all
