### Friday Puzzles #141

Why would you not enjoy putting numbers into a grid? I think this one has sent me slightly mad. If you get this in under 10 minutes I’ll be impressed. If you get it in under 5 then I may have to hunt you down and kill you. Enjoy!

### Friday Puzzles #101

For some reason I’ve found it necessary to make a nice easy example of a nikoli puzzle called Ripple Effect. It is the first such example I’ve done, and whilst I feel a little guilty putting something so tame out, a) for many readers this will be the first time they’ve seen such a puzzle, b) for a first timer it solves pretty nicely, and c) I have my mind on other things puzzling-wise. Hope you enjoy!
