<N7DOT> I still am unable to get to exit number 1... Pesky bots! I'm wondering though, Dave, if uploading a modification attempting to force escaping through the upper exit using minimalistic and 'just barely impossible' fixes to block the other doors (and removing the deadly aspect of the laser maze) would spoil the version you were intending to upload. If not, then once I can *actually* get to door 1 maybe I'll upload such a modification and call it 'The Accidental Puzzle' or something like that.

Oh dear, that was silly. Fix coming... Mark, you can ctrl-0 to get speedrun back :)

<Dave> OK, I'll have a quick try at explaining the transponder version because I'm never going to upload it anyway. I never fully tested it because it wasn't good enough but ...

You have a grid full of panles with crossovers in bizzaro and park transponders on it. The panels map to an identical grid of remotes with blocks in bizzaro. The remotes map back to the same spots on the original grid. If the bizzaro grid is fired horizontally from the right from it will turn all the crossovers making a path to the rightmost transponder, repeat from the left. Fire across the original grid, any number other than 2 or certain cases of higher even numbers will fail, 0 cancels out. Higher evens than 2 can be ignored anyway. Refire the same way to reset the grid to its original state and repeat vertically. Hope this makes sense ...
<Dave> PPS. I am still clueless about your dalek/teleport direction reversal mechanism. Every time I tried I came unstuck with multiple consecutive reversals.
<Dave> N7. Continuing from previous comment outside of the level comments ...

I'm curious, you are full of interesting ideas, how far did you get with this before? The difficult bit is testing two axes using only one 'singularly active' piece without introducing a huge maze of remotes. (by 'singularly active' I mean a piece that can only switch over one other cell). In the transponder version I mentioned before, the transponders are 'multiply active' because they are used as both a trigger and part of the test procedure allowing a bi-axial test for exactly two pieces on each line on both axes, this makes the zero test redundant.

The final implementation using 'singularly active' pieces (ie. spheres) only checks for an even number on each axis but is backed up by a 'fail on zero' test. This only works becuse four in a line is not possible without failing either the 'zero test' or the 'parity test' somewhere else.

PS. If you solve these levels every dalek dies, if you fail they don't. If you have access to a large enough monitor (I only have this at work), the animation of the test procedure, especially for Queens, is really good. :)

<N7DOT> woo solved it :) (with 2007 version of course)

<N7DOT> Oops, forgot a question I had: Is there a good reason why spheres were used instead of steel?
<N7DOT> You beat me to it! I had been planning an implementation of No Three in a Row, but that didn't get much work on it.
<Dave> The rules: Every sphere must be in the 9x9 field, no more than two in any row or column. Simple as that.
