OK - I think I'm first here...

Nice flowers! I think I have a long while before anything in my garden looks like those.
12:45 nice bright flowers
5:43. What beautiful flowers! No more winter!
is it believable that one can do these in under 10 minutes? how?
All good must be first nearly

ahh...if only spring would actually arrive. i have some crocus and daffodils and a few tulip leaves but not much else and I heard it was going to snow!
8:47. A few weeks ago I would have agreed with Aaron that there was no way to get under 10 mins., but you will get faster. 1. start the clock. 2. fill in the possibilities and partially solve as you go. 3. remove possibilities as you solve. I stil don't think it is possible to legitimately do these under 5 mins using pure logic, so that's the next challenge.
I like being in the first 13!!

2:02 after setup. Pretty much all sole candidate/unique candidate and basic line block (or whatever it's called) interactions. Nice flowers!
Hi Banans (is that right or was it a typo?).

If I do manual setup it takes about 3 minutes to do the setup. I usually just use 'Simple Sudoku' t do the seup automatically. The puzzle, once set up, takes me less time than the setup for hard, but it varies. Now tough, that can take a while.
Is it really going to snow there? We moved from MA to Tacoma Washington last summer and we are coming back to MA for a visit this Friday. I will be very upset if there is snow there!!!!!
16:15 - I'm with you Aaron. I've never done a hard in under 10, but I enjoy the puzzle and the beautiful photos. Those bright flowers really woke me up on a rainy S. Calif. morning.
4.18 Quite a basic one today, back for the tough later..
Maen to all. Won't be long till we get flowers here, though we're getting wet snow today. Oh well, spring is in the air!
Hi Banans (and all)
What is 'Simple Sudoku'? I cant see it as one of the option buttons?? Am I missing something?
7:46 Hi to all. That was good for me!
7:23 - with distractions! Lovely flowers ripe for plucking!!
7:46 Hi to all. That was good for me!

Linda from Massachusetts, I'll be in Mass. this weekend & am looking forward to seeing some daffodils & tulips...so far up here, all I've seen are a few crocus!
Not too bad for a Hard. Pretty flowers, too!

To Aaron from Philadelphia - in a word -- No!
under 10 minutes...NOT counting the set up...that's believable. We should start timing setups too...how long does it take to do an accurate one????
7:53 I know my setup time is increasing because I am doing more of the solving during setup, and that is just a matter of experience, seeing patterns. Guess I could have looked for solving technique links last summer when I started these, and maybe my hard times would be under 4 min. by now like some, but I did it myself!
