In computer technology, a location where a memory card or other data storage device can be inserted to add capacity. A slot may be one of several different types, including ISA (industry standard architecture), PCI (peripheral component interconnect), or AGP (accelerated graphics port). In addition to slots for media cards, modern motherboards frequently include expansion slots for various add-on devices such as sound cards, video cards, and hard drives.

Myth 1: The machine you play is “due to hit”

This is a common belief among many casino players, but it’s unfounded. It’s based on the misunderstanding that each machine has its own set of paytables and random number generators, so if one machine in a row doesn’t have a good payout history, it is due to hit soon. The reality is that each machine in a casino has the same random number generator, which sets combinations of symbols on each reel every millisecond. In order for a particular machine to pay, you need to be there at the exact moment that the winning combination appears. This is why people who leave a machine to go get coffee or use the restroom can see someone else winning on that same machine in the same split second.
