Got the pattern easily enough but took me a while to actually place a digit. After that it was nice and smooth (apart from the 10 minutes I spent blindly staring at a missed triple). Thanks for sharing!

Fun puzzle...if you know the basics, probably more of an enjoyable 1* puzzle. Thanks for sharing.
