I predict this will be the first Thursday under a minute. I did it twice in two minutes myself, but sadly the first time was wrong. We might be unlucky though, since there a couple of unusual patterns to find:



Actually, now that I look at it, I doubt most people will use the first pattern. The line on the left of the 2 is already there, so you could just count instead.

Didn't know the 3 2's was such a special pattern automatically used it without thinking about it. I derived by using the 1 in the corner but it seems it works without the 1 as well. But i agree it went really quickly. My fasted thursday time so far. Strangely not faster than my fastest friday time though.

I use these very often and I explain them by counting using corner 2 propertis: "here"

Even without the 1-2-1 wall, a line above the three can be deduced. You don't need the 'even number of entries into a region principle'. By the way, a 1-3-1 wall works as well!

havn't shared my patterns for a long time already, actually it's because my busyness...

if there're enough informations for counting, at least one line around the "3" can be deduced. (similar if that's "1" not "3")


that's why I stated that "2" is useful in counting "also here"


this is the basic of counting: (for more :"Puzzles sharing")


basic of counting combine with loopy rules : (at least one line can be deduced)



Let's play: (make sure you are familiar enough with counting, then you can do it within one minute)
solution are the little "?"s

I'm not saying you're false,
I just state that in order to have the effect of wall 121 with 3:

i.e.

we combine the effect of:

i.e.

and:

i.e.


also, wall 121 with 3 don't need the 'even number of entries into a region principle'
...I've already confused many people here by using my poor english...

You are overestimating me! Here's another local puzzle: (2 lines and 3 crosses can be deduced)
