Now, they offer what most slot players strive for–boosting their winning chances, provided they select the right game to make it work. Slot machine features add excitement to slot machines, but there is much more to them than mere entertainment. Video slots developers have pushed boundaries over the past years, developing games with five or more reels, numerous paylines, different bonus rounds and special features, not to mention HD video and 3D graphics. These hugely popular slots are operated by software developers and play out like video games without the limitations of three mechanical reels. Online slots have come a lot way since the days when traditional fruit machines with three reels gained popularity in pubs, clubs, and multiple casinos worldwide.
