Windoku Killer 4 (WK 4)

[Nasenbaer]

You thought you would get a nice and quiet weekend? No way!

I know, Jean-Christophe posted one just a few days ago. But this one was already waiting for you. And since UA99 was not too hard I thought I should give you something else to do for the weekend.

So here's Windoku Killer 4 v1.0 (WK4v1.0). My estimated rating is 1.0 (despite of a tricky move I used). Don't forget your basic skills but be sure to know where the extra windows are.

Like in WK 3 is used the Innies and Outies of the Windows to crack it.

WK 4 Walkthrough:

1. R6789

d) Outies C89 = 9(3) <> 7,8,9
e) 9(3) @ N9 <> 6 because R7C8 <> 1,2,6

3. R6789
a) 6 in R678C159 locked in 15(3) @ R6C5 for C5 -> 15(3) = 6{18/45}
b) Killer pair (68) locked in 20(3) + R7C2 for R678C234
c) 14(3) @ N7 = 7{25/34} -> 7 locked for R6
d) 16(3) must have 1 since together with 10(3) it's only possible there @ R78
e) 16(3) = {168} -> R6C5 = 8 (locked for R678C159); {16} locked for C5+N8 + R678C159

6. Rest is singles with considering the windows.

The doctor is back! He says: Have some more!

Here's v1.5 with a slightly altered cage design. Be sure to have your combo tables at hand! My estimated rating: 1.25

I can't say that V1.5 was harder than V1. I used Innies+Outies to crack it where in V1 I used small combo analysis (Killer pairs).

Let's see what V2 has to offer.

Hmmm. I have to confess I didn't see the easy start in n3 because I was focused on n7 and n9. This makes it a lot easier.

I'll now look at your walkthrough, later there will be v2.0 waiting for you.

I should have named it WK4 v0.5, not WK4 v1.5. Thanks to Afmob who found the easy way.

This one is a lot harder. My estimated rating: 1.5. I hope I didn't miss an easy start this time. So here is v2.0.

That WK was even a bit harder than JC's WK 3. I took me some time to find the important move (step 3h) though the move itself wasn't difficult.

My endgame is quite messy so you can stop reading after step 3 (or maybe 4) .

Thanks Nasenbaer, for offering this interesting Killer variant!
