AND HERE WE GO AGAIN: GUESS WHAT? 5! THE STANDARD RNG AND SEED LIKE ALWAYS.  
  
THIS TIME THE PUZZLE IS SOMETHING VERY DIFFERENT. YOU NEED KNOWLEDGE OUT OF THE SCOPE OF BOULDER DASH. BUT THAT'S LIFE.. :)

YES A 'GLIDER' CAN BE FOUND AT THE LEFT SIDE OF THE MIDDLE FLOOR. IT MOVES SOUTH-EAST! :-D

arno, CORRECT! IT WAS QUITE FUNNY THAT A GLIDER HAPPENED TO BE FORMED :) NOW THERE'S ANOTHER HINT. LET'S SEE IF THERE'LL BE MORE "I GOTS" NOW BEFORE I REVEAL THE ANSWER.

THE CORRECT ANSWER IS THAT "CONWAY'S GAME OF LIFE" ( <a href="https://en.wikipedia.org/wiki/Conway%27s_Game_of_Life" target="external">HTTPS://EN.WIKIPEDIA.ORG/WIKI/CONWAY%27S_GAME_OF_LIFE</a> ) TRANSITION RULES ARE APPLIED ONCE TO THE ORIGINAL CAVE LAYOUT. THIS TIME THE HINT WAS QUITE STRAIGHTFORWARD :) THE GAME OF LIFE IS PRETTY WELL-KNOWN, AT LEAST BY NAME AND APPROXIMATE RULES, AND ESPECIALLY AMONG RETRO GAMERS, SO I EXPECTED TO SEE MORE THAN ONE ANSWER THIS TIME :)  
  
THE RULES ARE SIMPLE:  
  
- ANY LIVE CELL WITH FEWER THAN TWO LIVE NEIGHBOURS DIES, AS IF BY UNDERPOPULATION.  
- ANY LIVE CELL WITH TWO OR THREE LIVE NEIGHBOURS LIVES ON TO THE NEXT GENERATION.  
- ANY LIVE CELL WITH MORE THAN THREE LIVE NEIGHBOURS DIES, AS IF BY OVERPOPULATION.  
- ANY DEAD CELL WITH EXACTLY THREE LIVE NEIGHBOURS BECOMES A LIVE CELL, AS IF BY REPRODUCTION.  
  
IN THIS CASE BOULDERS REPRESENT LIVE CELLS AND DIRT AND SPACE DEAD CELLS. ANY OTHER OBJECTS ARE IGNORED AND JUST LEFT AS THEY ARE. IF THERE WAS DIRT OR SPACE WHICH HAD EXACTLY 3 NEIGHBOUR BOULDERS (ALL 8 ADJACENT SQUARES ARE COUNTED AS NEIGHBOURS), THE OBJECT WILL BECOME A BOULDER. AND IF THE OBJECT WAS A BOULDER THEN IT WILL STAY ALIVE IF THERE ARE 2-3 NEIGHBOUR BOULDERS, OTHERWISE IT WILL DIE AND BECOME DIRT. TRANSITIONS ARE MADE SIMULTANEOUSLY SO THAT TRANSITIONS WHICH ARE MADE DURING THE SAME ROUND DON'T AFFECT THE RESULT OF OTHER TRANSITIONS. THIS IS DONE BY DOUBLE BUFFERING THE GAME FIELD AND THEREFORE THERE'S NO BD-STYLE "SCANNING ORDER"  
  
IT'S QUITE FUNNY THAT AFTER APPLYING THE GAME OF LIFE RULES, A GLIDER WAS FORMED ON THE CENTER LEFT SIDE. IT'S AN ICONIC GAME OF LIFE FORMATION AND IS THE SMALLEST MOVING FORMATION. BECAUSE OF THAT FORMATION I PROBABLY COULD HAVE REMOVED THE "BUT THAT'S LIFE" HINT AND STILL SOMEONE WOULD HAVE REALIZED WHAT'S GOING ON :)

THE FIRST TIME I HEARD OF THE GAME WAS ACTUALLY WHEN arno MENTIONED IT IN THE "DANCING FLY FORMATIONS" THREAD. I HAD A QUICK LOOK AT IT ON WIKIPEDIA AND THEN ALMOST FORGOT IT AGAIN. THAT'S WHY THE HINT "BUT THAT'S LIFE!" DIDN'T HELP - I JUST FORGOT THE NAME OF THE GAME. IT WAS ONLY WHEN arno WROTE HE DISCOVERED A GLIDER FORMATION THAT I REMEMBERED IT, BECAUSE THE KEYWORD "GLIDER" WAS THE REASON FOR ME TO LOOK IT UP BACK THEN ;D

darkstoorm: INDEED A DFF! THIS ONE IS DESCRIBED IN MORE DETAIL IN EPISODE 15 OF THE DFF ARTICLE SERIES:

BUT UNTIL NOW I DIDN'T REALIZE THAT ONE OF IT'S PHASES LOOKS LIKE THE GLIDER FROM 'LIFE'; THAT'S VERY COOL! ;-D
