The Slot Machine Technology That Makes Them Work

There are thousands of slot machines on casino floors and online, with new games dreamed up all the time. While these devices vary in appearance and bonus features, they all use a similar technology. Read on to learn the essential concepts that make them work.


A position in an NFL offense where a receiver lines up between two wide receivers. Typically shorter and smaller than outside wide receivers, slot receivers have to be exceptionally quick and precise with their route running. They must master just about every type of passing route, from the inside and outside to the deep and short, and also be able to sync up with the quarterback on timing. In addition to their route-running, slot receivers must be able to block effectively, filling in for the fullback or extra tight end on running plays like end-arounds and pitch plays.

The slot is an extremely important position in the modern game, with many of the best players in the league specializing in it. Tyreek Hill, Cole Beasley, and Keenan Allen are just a few examples of NFL receivers who thrive in the slot.

When you play slots, a random number generator (RNG) software determines how symbols land on the reels. This determines whether you win or lose, and the amount you earn. Most slot games are calibrated to return between 90%-97% of the money that you put into them. However, the exact percentage will depend on the machine you’re playing.
