Many people believe that slots pay out in cycles or have a specific pattern to them. However, this is false. Slot machines use Random Number Generators to generate thousands of numbers every second, each of which corresponds to a particular outcome on the machine. This means that the machine does not know whether it is about to hit or not.
The earliest slot machines were mechanical, but nowadays they are almost all electronic and connected to a central server. This allows for quicker payouts and a wider range of options. Some casinos even offer progressive jackpots, where the winnings from several machines in one casino are pooled together and the jackpot can grow into millions of dollars.
