Konami Slot Machines Flashing Subliminal Messages?

shadowspar writes "A Canadian province has pulled several models of Konami slot machines out of service after a news investigation revealed that they briefly flash a jackpot result on the screen every time they are played. Konami claims that the 'subliminal' jackpot images are unintentional and the result of a bug, but other US and Canadian jurisdictions are looking at pulling the machines as well."

Casinos grew suspicious after younger and younger players continually cleaned out the machine in a methodical manner before eventually treating their "conquering" of the slot as a standard Saturday morning ritual.

      What's up with Canada? This happened in 2000:

      A manufacturer of computerized gambling equipment, WMS Gaming, of Chicago, earlier this year sued Edmonton, Alberta, software consultant Zues Yaghi for $10 million after he showed the company and Canadian authorities a "back door" he'd discovered in the company's casino slot machines.

      In a case that was reported in Canada, but mostly ignored elsewhere, Yaghi went to officials of the Alberta Gaming and Liquor Commission, who videotaped the consultant winning hundreds of dollars, according to The Edmonton Journal. He turned all the money over to the officials on the spot.

      Both Yaghi and the manufacturing company say the software error in the machines allowed millions of dollars of fraudulent gains. At least two people other than Yaghi took advantage of the bug at casinos in the United States and Canada before the software was fixed, the company says.

      Yaghi may have erred when he proposed to the company that they hire him as a consultant to find and repair such flaws for a fee of $250,000. The company offered $50,000 instead, which Yaghi declined.

      The company then obtained an order from a Canadian court to seize computers from Yaghi's home, persuaded the gaming commission to ban him from Alberta casinos, and filed the $10 million lawsuit.

      In response, Yaghi is suing WMS Gaming for $1 million and the gaming commission for $3 million.

      The Neurophysiology of Response Competition: Motor Cortex Activation and Inhibition following Subliminal Response Priming
      Peter Praamstra and Ellen Seiss

      University of Birmingham, UK

      Some widely used tasks in cognitive neuroscience depend on the induction of a response conflict between choice alternatives, involving partial activation of the incorrect response before the correct response is emitted. Although such "conflict tasks" are often used to investigate frontal-lobe-based conflict-monitoring processes, it is not known how response competition evolves in the motor cortex. To investigate the dynamics of motor cortex activation during response competition, we used a subliminal priming task that induced response competition while bypassing preresponse stage processing conflict. Analyses of movement-related EEG potentials supported an interaction between competing responses characterized by reciprocal inhibition. Inhibitory interactions between response channels contribute to the resolution of response conflict. However, the reciprocal inhibition at motor cortex level seemed to operate independent of higher level conflict-monitoring processes, which were relatively insensitive to response conflict induced by subliminal priming. These results elucidate how response conflict causes interference as well as the conditions under which frontal-lobe-based interference control processes are engaged.

      The neural bases of subliminal priming

      Stanislas Dehaene

      Psychologists have long reported that words that are made invisible by forward and
      backward masking can nevertheless cause behavioral priming effects. Functional
      neuroimaging can now be used to explore the neural bases of masked priming. Subliminal
      priming causes reduced activation in multiple areas (fusiform gyrus, intraparietal sulcus, and
      motor cortex), in direct correspondence with behavioral manifestations of priming at the
      orthographic, semantic, and motor level. This implies that a whole stream of processors can
      operate unconsciously. The neural code in each area can be assessed by varying prime-target
      relations. A simple mathematical framework is proposed that tentatively relates priming at the
      voxel level with the shape of the tuning curves of single neurons in the underlying tissue.
      Priming thus provides a general method to study the fine microcode in each brain region (the
      'priming method').

It can for example easily happen when try to place a sprite on the screen, but only initialize its positions position value after having gone through the draw loop once, i.e. something like this:

    1. call update() to handle game events, one of them triggers the creation of a new object A
    2. call draw() to draw the current game state
    3. call update() and only now finalize the initialization of object A now
    4. call draw() to redraw the screen again

    With that code you would get some object flashing up at some random position. Other easy causes for random flashing could be texture loading that happens in a separate thread, since the game doesn't wait for the texture to be fully loaded, it will use a placeholder texture for the first few frames of a new scene till the real texture is loaded (see for example Halo2 on XBox). If that placeholder texture happens to not be specified the renderer might just use whatever texture is just in memory and so you would get the desired effect of textures appearing in the wrong places. Double buffering can also lead to all kinds of subliminal errors.

    I've been developing casino-type games for over 12 years, so I know how they work. This is not at all surprising since slot machines are entirely based on fraud and conning you into believing and 'feeling' like you have a chance of winning - this is just another step in that direction.

    The most sinister devices employed by the slot machines are the most fraudulent. I am referring virtual reel mapping and the near miss system. Here's how they work:

    Virtual reel mapping works like this: You think that a reel has 24 symbols (12 symbols, 12 blank spots) and conclude that your chances of obtaining any particular combination is 24^3. Not so. What happens is that the slot spins 3 virtual reels, each one consisting of 32 symbols. Positions on the virtual reel are mapped to positions on the physical reel, but guess what, the virtual reels have 8 extra symbols, and they're all mapped to blank spots on the physical reels! This significantly reduces your chances of obtaining a winning combination.

    The near-miss system works like this: Considering the virtual reel mapping mechanism described above, the near miss principal works on the basis that the extra 8 blank spots on the virtual wheel are mapped to locations on the physical reel RIGHT NEXT TO the jackpot symbols. That's why you'll see "7 BLANK 7" and "7 7 BLANK" with frightening regularity.

    And here's the kicker: There are jackpot symbols on the physical reels that aren't mapped to the virtual reel. Which means that there are symbols on the physical reels that will NEVER EVER show up on the pay line. If that isn't outright fraud, I don't know what is.

    If one puts on their cynic hat to appreciate slots from a purely human-psychology point of view, one can truly appreciate how masterfully crafted the whole set-up is. It disgusting and magnificent at the same time.

      24 stop reels are very rare (never seen them in the real world in fact) because it makes the 12 symbols have to be pretty narrow. 22 stop is the standard although 18 stop was used from time to time. Virtual reels were commonly 72 stop. 32 stop doesn't extend the odds enough to be very useful and it also doesn't give you enough granularity between positions. You can go higher than 72 of course. I saw a math model for an IGT Five Times Pay that used a 90 stop virtual reel and one for a Triple Triple Diamond that used a 200 stop virtual reel. Those were 92% payout games if I remember rightly. I was told Quartermania used 255 stop virtual reels but I never personally saw math for it.

      As a general point for people I'd like to say that there are indeed several techniques the machines use that are not commonly known, but all slot machine behaviour is VERY heavily regulated by law.
