Can we start deleting unnecessary old versions of this and mods (if any) so I don't have to solve them? ;)

I agree that a strip of electric on the bottom will call too much attention to the blue sphere.

362 Memory Hole (v4) mjn (96) Mon 21 Feb 2005 18:38 SPOILER

Okay, here are my thoughts on fixing it:

Item #1: If, at any point, the two black spheres are next to the laser, the panel must be used.

Proof: The second (leftmost) can't move until the first moves, and the first must go down. The second must then go right, because you can't stand in front of the laser to push it left. At this point, it can't go up or down, so it has to go into the hole.

Item #2: If there is electricity below the two black spheres, then they must go into the hole-area, and before any other spheres can.

Proof: At the start, the blacks can't go up or down without disappearing, and the can't go left without some other sphere first getting stuck on the left wall, so they have to go right. The last blue is the only colored sphere that can be pulled out of line safely, and it can't go into the hole before the blacks because there's no way to bring a block down until three spheres are lined up at the hole.

It may still be possible to destroy a black and then use a block in its place, but you'd still have to take a green or red out of order, which could only mean catching it with the blue once it's on the right wall, and then there'd be no way to get the blue in before it.

Anyone see any holes in this?

Yeah, I was thinking about the strip of electricity, but I'm worried that it might draw too much attention to the last blue sphere's unique situation.

I was also thinking about putting a black square in the bottom right corner of the main space, like you did in Memoryless Hole #2. Would that break your cook? (Mine involved bringing the second black sphere down, then bringing a red down on top of it.)

Hmmmm. My intuition is that if we add a strip of electric at the bottom, like in Memoryless Hole v4, that should make it impossible. Not quite 100% sure, though - it's close. For example, I think that level would have been cookable if the blue panels surrounding the memory hole were electric.

I'll let mjn have the honors, though, at his leisure. The basic idea of the level is very cool.

358 Memory Hole (v4) Tom 7 (1) Mon 21 Feb 2005 10:02 SPOILER

Ah, we gotta get an uncookable version --- any tips, Brian?

355 Memory Hole (v4) bpotetz (144) Mon 21 Feb 2005 02:23 SPOILER

Cook: Booyah!
This is too good to describe in a post.
You'll have to solve it yourself in yet another memoryless level.

(You came really close that time, mjn)

After much consideration, I'm pretty sure that this version finally does away with all the non-panel solutions, so I'm gonna call this the "final" version.

(Since Memoryless Hole preserves those solutions, I guess versions 1 and 3 could be deleted, if you want, Tom.)
