While a physical slot machine uses revolving mechanical reels to display and determine results, a video slot is powered by software that randomizes a sequence of numbers and finds matching symbol positions on the reels. The computer then causes the reels to stop in those positions, and the symbols that appear on the payline determine whether you won or lost.

In addition to the pay table on the face of the machine, a video slot typically displays a help menu that describes how to find and understand the various options. Often, this menu includes information on how to activate bonus features and other special functions that can boost your bankroll.

Historically, all slot machines used revolving mechanical reels to show and count combinations. However, the mechanical reels were limited in number and speed, so manufacturers created electronic equivalents that are now the norm. These are called video slots, and they have the same basic functions as their ancestors.

In modern video slots, the reels are displayed in a window and the symbols are represented by lights. The video screen also shows a status bar with information on the current game and its history. In addition, players can access game settings and rules by clicking the “Help” button or “Show Rules” link. If the player has not registered, he or she can click on the “Register” link to create an account and get started playing for real money.
