I'm back ! Just got home from my latest Vegas trip. There is a whole new generation of machines there now, many of which are updated versions of the 'traditional' Double Diamond style machines, using white LEDs for the reel illumination, and so on. However, there are also a whole bunch of machines now that at first glance look like a conventional one, two or three credit per play machine, and still have traditional themes like Lucky 7s or Double Diamond, but are actually like the 1c and 5c machines where you can play up to 25 lines with a variable stake per line. To set that up, they usually have two rows of very conventional internally lit buttons, but on some of these latest machines, they have just a few buttons that at first glance look like a standard oblong button, internally lit yellow, but on a closer look, actually contain a miniature backlit graphical LCD panel. How cool is that ? The legend of the button can be changed 'on the fly', and when it's not performing any control function whilst the reels are running, it can dance away with pretty little patterns and graphics.
I can't recall having seen buttons like this on any other equipment before, but what an obvious idea it is. How much better for multi-level control functions, than having to display what's going on on a separate LCD panel. Anybody else seen them used on any other equipment ?
