How Bonus Rounds Work on Slot Machines


Slot machines are simple gaming devices that accept coins or paper tickets with barcodes as payment. They spin reels and if a winning combination is struck, the player is awarded credits according to the paytable. Slot machines vary in symbols, although classic symbols often include fruit, lucky sevens, bells, and a stylized version. Bonus features are also common, and are usually aligned with the theme of the slot game. Several common variations of slot machines exist, including Video slot machines and classic reels.

Video slot machines have a video image rather than actual rotating reels

While the basic operation of video slot machines is similar to that of regular machines, their main difference is the use of a video image instead of actual rotating reels. Instead of spinning reels, video slots use photoelectric cells that generate current when light strikes them. Each reel is equipped with a photo diode and a light source that is controlled by an electronic circuit. The photo diode detects the position of the reels based on the current level.

Machines with multiple pay lines allow players to choose how many pay lines to play

Most slots with multiple pay lines allow players to select the number of lines they want to play. A minimum bet is only a single line across the reels, and you can choose to bet on additional horizontal and diagonal lines as well. In the event you win, you’ll only be paid if you bet the maximum amount per line. But if you’re a high roller, the more pay lines you’re playing, the higher your payouts will be.

Bonus rounds

The bonus rounds on slot games come in two different varieties. They can be separate features within the slot’s main game, or they can be a part of it, with extra reels and special symbols. Bonus rounds can also come with multipliers, sticky wilds, or other special features. Bonus rounds are great for adding a new dimension to slot games, without causing players to lose all their casino balance. Here are some of the different types of bonus rounds and how they work.

Payback percentages

The payback percentage of a slot machine refers to the amount of money the game will pay back to the player after the machine has taken its profit. This number is usually higher when the game costs more, so it makes sense to avoid slot machines with a low payback percentage. In general, casinos will program their machines to pay back a lower percentage of money than they would if the game was free. A typical payback percentage for a slot machine is around 75%.
