Great job. I am so glad to hear that. Are there any strategies or techniques in particular that you struggle with?

@@SmartHobbies The one in the last video. And the XY pairs and fish something (I don't remember their names), I can't spot them! Haha

Well constructed puzzle, most enjoyable to solve without notations. A little bit of hesitation at the start, and indeed, I haven't seen anything else to get moving other than the 3 in r1c7. With this, the next digit is the 7 in r1c5 and in r5c5, then the 45 oblique pair in block 2, the 2 in r2c5 and the 3 below that 2. So not much thinking necessary, the 15 pair in block 8 is just sitting there :) And of course, the 38 pair in row 9. A good catch from there is that we now have a 27 remote pair in row 9 at col 3 and 8. This is how, without counting numbers (which I do so badly) you have the 1 as the only possible digit in r9c1 and the 5 at the other end in col 9... The puzzle at some point also becomes a good exercise to try and keep pairs in mind to find further restrictions. Not always evident,, for example I lost track of the 79 pair in the top row of block 4 at some point while solving the middle horizontal portion of the grid... Just lost a bit of time and finished in 18 minutes. Thanks for posting, this was a good demo and a fun puzzle.

I wouldn't have identified the first 15 or 3. Well done. That being said, I wasn't completely surprised, because I am getting better using your strategies regularly.

I assume that the strategies are these: notice the pairs, the triples, and at least one quad. (The quad in row 1 finally cracked the puzzle for me.) Backtracking, I noticed a triple that I missed, but as that was after the quad, I was just too busy unraveling everything else and it didn't matter. BTW, I have adopted Rangsk's practice of looking for repeated digits in each band. It helped minimally here. 0:50 It's true. I didn't place a single digit until I noticed the 3 restriction in column 5. I wish that I'd noticed it when filling out column 5. I wish that I'd noticed it when filling out block 2. I noticed it after centermarking the entire grid. Once I noticed column 5's restriction, and removed the other 3s from block 2, I found the 1269 quad in block 1 and placed the 7 and 3. 4:40 And now I have no idea why I stopped cornermarking once I finished with the (virtually non-existent) 8s. Cornermarking 9s would have caught that 49 pair. (I already had 4s marked.) I think I was going after empty cells, hoping for something. Row 9 gave me a 27 pair. Later on, filling block 8 gave me a 15 pair, a 38 pair, and finally the 49 pair.

Finding the 3 was key to this solve. This was a pretty tricky solve for SGP. Thank you for the comments.

I had a hard time getting rolling on this puzzle. I knew there was a break-in point that I hadn't found, but once I found it I was able to finish. Just too bad that much time was lost early on. Total time, 25:32, with no help from anything except glancing back a few times at the 'strategies demonstrated in this video' list. That wouldn't be considered cheating, would it?

I would not consider that cheating, Brad. I put the strategies there to help people but it is not telling you where to use it.

@@BradJames878 yes. The only info they get is order of puzzles (easier is usually in the front) and point values if they get right (harder puzzles give you more points).
