Windows 8 dreamboard5/6/2023 When you make your first click, which is never a mine, a random spot if picked on that net and whatever size board is positioned around that spot. What I'm thinking is that there is a huge pattern of infinte mines and patterns that stretches forever (?) in a 2-dimensional plane. I'n sure many of you have experienced this too. The patterns that were shifted appeared on the oppsite side of the board. I've has a board that was my 10 board, shifted left about six rows and up about 10. The first mention of possible shifts came when Matt posted, "Just a little theory about the board generator: I've noticed many a board that is basically a shift of another board. The board on the right is a shift of the Dreamboard. Is it possible to know how mines are placed on the board, how "randomness" is made by the program?" No one had an answer. Emmanuel Brunelliere (France) posted, "The 16 I've just got finishes on the same board that Damien Moore's 14. On Owen Fox (Ireland) tied his record of 18 seconds - on the same board he had made his original score of 18! Marc Schouten (Netherlands) noticed Matt already had made a video playing that game. Matt completed the Dreamboard in 14 seconds. If you try to copy you will miss out on the other boards." Joe Nuss (USA) wrote, "With the crazy frequency with which that baord has been showing up, i bet everyone here's had it at least once" adding that it "makes you think."Įxamples continued to accumulate. I don't know if I'd want to get that board though.I make it a rule not to try to get other peoples games.so far I got two 14's and today a 15.all excellent boards, of course. Three days later Matt blasted while playing the Dreamboard. I wish there was a way to guarantee a fresh board every time someone starts a game." It turned out that Robert had not chosen the PRNG and was unable to offer an explanation. By this point at least six examples of duplicate games had been found.Īfter Damien mentioned he was talking to Robert Donner, Dan Cerveny (USA) posted, "It will be interesting to see what Rob Donner says about the random board generator. His only complaint was not recognising the game sooner and making a faster score. On Damien recognised a Beginner game from one of Matt's videos, and he did the last three clicks from memory. David Barry (Australia) noted perhaps minesweeper used a small set of boards, similar to the way Freecell used only 32000 boards. He pointed out that such a case would have repeating patterns, and the way to make truly random boards would be to use a PRNG with a repeating pattern greater than the number of possible boards for each grid size. This would limit the number of boards on each level to a maximum of 65535 variations. Brett Piatt (USA) proposed that the game used a pseudo-random number generator (PRNG) creating 16 bit numbers. In that case, the Dreamboard would be close to the beginning of the sequence. One possibility was that Gernot had played on a second computer or had downloaded Winmine again. The same player getting a board twice was a shock than the existence of duplicate boards. Posting on he wrote, "Wow! 12 in intermediate! And Gernot got the SAME EXACT BOARD AGAIN!!!!!!!!!!!!!!! Hmmmmm, something's not right in the game of minesweeper." There was a delay posting the score on Authoritative Minesweeper, but Matt McGinley (USA) realised immediately it was on the same board. Gernot then broke his record again on, jumping from 15 to 12 seconds on Intermediate. The main feature was several screenshots of what became known as the Dreamboard. Damien posted an article on called "Random Games?" and collected examples. It soon became worrying that despite the vast number of presumed mine arrangments, records were often being made on the same boards. Over the next few months more duplicate boards were noticed. Unfortunately, the Guestbook posts from this era are lost. Thus everyone would see each board once in their lifetime in the same order. Now it was believed games generated randomly from a fixed starting point. A few days later, Lasse Nyholm (Denmark) noticed that the game was identical to an earlier 18 second game scored by Damien Moore (Canada). This changed when Gernot Stania (Germany) set a world record of 15 seconds on the Intermediate level. It was originally thought boards were generated randomly.
