Last week I didn't contribute a Sudoku to the Daily League, but this week I'm back. This week features another Frame Sudoku variant. As I'm a fan of most sudokus with sums and I'm pretty good at them, writing these generally comes pretty easy to me. It generally avoids the annoying problem of running out of solutions. I'm pretty sure I've seen this variant before. I'm just not able to remember where I have.
The last few Sudokus had been a bit easier than some of my others. I think this one will again be a bit more challenging, because it has a bit narrower solution path. I think I used the rules pretty well and it stays challenging till the end. I don't want to scare anyone off. I don't think there are any really hard deductions. I just expect slower times than in the previous few weeks. I hope you all enjoy it.
