based on dsm dash 8, cave c  
  
story:  
After Rockford mastered the exam, the demon seemingly keeps his promise and leads him into a room with a lot of boulders and magic walls! However, as soon as Rockford enters, he hears a door slamming behind him and an evil laughter! Now Rockford sees the problem: the magic wall at the bottom will absorb almost all the treasures he creates! Can he still save enough diamonds to escape again?  
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\  
  
why i especially like this cave:  
\ with the additional magic wall at the bottom, this is a classic-style unusual puzzle where ^ has to secure as many \\\ as possible before they vanish in the absorber!  
\ the only cave of dbd19 where the random seed has a huge influence on the difficulty!   
  
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\  
  
how many \\\ are possible? i remember i tested this cave on two consecutive days and i got 2\\ both times, but i'm not sure whether tit was the same 2\\ each time... :d

 dustin , well there are definitely more than 2\ possible because i can see 4\ right away and there are a few additional interesting spots. but too tired now; i'll take a closer look tomorrow :)

ok, with  nicol 's help i've got 3\\\ now. maybe these are the three which i collected on both testing sessions together :d

 dustin , i'm working with my solution.. currently 9\ but i'm finally done i think. this a crazy cave. after 6\ i already thought there's no more.. :)

it's always fascinating how random generated caves can offer difficult challenges! i'm curious... :d

 nesdori , do you still want to "prove" your 9\ or are you still looking for more? :d

 dustin , i really don't have more ideas so my 9\ free. 8.5 fps is quite hard both to execute moves and watch them. so i recommend slow-motion especially for 3|+ sequences to see what each | is doing :) it's also possible to get a \ from the three rigthmost |:s intead of four but it needs a lucky push. as there's no other use for the fourth | i of course chose the deterministic non-lucky variation :) i also made another 995 points solution demonstrating the 3| way to do it.

 nesdori , ah yes! the idea of stopping a falling \ for one or a few frames has far more variations than i was aware of! great run! :d

 dustin , it's funny and astonishing how effective randomness sometimes is. if i had this general idea and i had to place walls by hand the resulting cave wouldn't have been this good. what seemingly was "zero \ cave" suddenly is 9\ cave, just amazing.. :)

 nesdori , indeed! i think there's one big difference between human-built puzzles and randomized ones: if you solve a human-made puzzle, you automatically expect a human brain behind it and you try to find the author's intention behind this or that detail of the puzzle. (at the moment, i note that effect a lot when i play uwe drichel's collection.) on the other hand, if you just randomize something and then try to maximize this randomized puzzle (here in bd in terms of max\), then you know it makes no sense to look for "intentions". you just have to try and develop techniques, and it's a lot more about trial and error than in human-made puzzles.  
  
other actual example: chess :d if i open a chess book and see a diagram which says "white to move - what would you play?", i expect something special to be in the position, and my thinking automatically differs from how i would think about the same position in a real game. an interesting idea (which i haven't tested yet) would be to pick up some random game in the database, click on the position after white's 32th move and try to find a move for black :d
