Online slots definition

Online slots are simply defined as a game of chance consisting of different reel arrangements. These reels are populated with various symbols, and each round starts when the reels start spinning and end when they stop. Winnings for each round are determined by matching symbols, usually listed on the slot’s paytable.

As one of the most played games worldwide, online slots are identified with different names, including video slots, fruits machines, and pokies. Since the 1800s where slot machines were physical, the current technology has implemented virtual reels and Random Number Generators for an excellent online gaming experience.

Different types of online slot machines and games

Over the years, the slot machine has gone through impressive changes to make the game fun to play and rewarding. In Pennsylvania, there are different types of online slots available for players to try their luck on. To increase your winning chances, you need to know the varieties of online slots. Below are the six major types of online slots you will find at PA online casinos.

Classic three-reel slot

Classic online slots are the simplest form of online slots and are sometimes referred to as the one-armed bandit. The nickname came from the original mechanical way of spinning the reels. A lever was used, and when a player pulled the lever, a spin was executed. These classic online slots are the building blocks of the famous Las Vegas casinos.

Classic online slots are the best for new slot players because they are easy to learn and play. It consists of three reels, and a winning line is formed by matching three symbols. However, this type of slot has its limitations because there are fewer possible combinations. Furthermore, the variance is usually high, which means you can win or lose quite a lot.

Five-reel slots

Five-reel slots are among the most played online slot games. This makes them more abundant in the lobby of most online casinos. Unlike the traditional classic slot, this design was the first to implement a digital spinning mechanism. They feature a spin button, amazing graphics, and sounds. Five reels slots were the original pioneers of the modern online slot gameplay.

The slot has fewer limitations, thanks to the increased number of paylines and odds of landing a winning line compared to classic slots. Furthermore, bets can last for long, and the game sometimes includes a jackpot that promises to give high rewards. One of the features that defined the five-reel slot is the introduction of bonus features like multipliers and free spin rounds.

Six and seven-reel slots

Six and seven reel slots are among the new designs challenging the standard traditional reel arrangement. They use the same regular grid as the five-reel slot but with 6Γ—3, 7Γ—3, or more setups. More reels mean that players can create long winning lines with longer matching symbols. Combining such a design with features such as wilds, respins, and stacks create an exciting gaming experience.

Other slots use the six and seven-reel slot design with different rows to go beyond the usual slots and create unique structures. Biggers gaming grids also create new slot bonus features as well as the ability to include more scatters and wilds per round. This makes it easy to trigger free spins and other bonuses available.

Progressive slots

Huge winning on online slots is attributed to progressive jackpots. In these types of slots, part of the wager amounts from players contributes to the jackpot prize that can be won at any time. Most progressive slots have the jackpot amount displayed on the gaming screen. Other slots refer to the progressive jackpot as an accumulated jackpot.

For a better and quicker rewarding progressive jackpot slot, online casinos interconnect the games for quicker contributions. Jackpots can go up to millions of dollars but remember that the higher the jackpot amount, the slimmer the chances. One drawback for these types of slots is that you need to place the max wager amount to qualify for a chance to win the jackpot.

List of online slots with the highest RTP

Experienced online slot players understand that one of the most essential pieces of information about slots is the Return To Player (RTP) value. The value determines a rough estimate of the amount players can expect to win in the game’s lifetime. RTP is calculated on a long-term basis rather than per wager, thanks to slots being random. So, what slots have the highest RTPs? Below are the top 10 slots with the rights RTP.

  1. Ugga Bugga (Playtech) β€” 99.07%
  2. Mega Joker (NetEnt) β€” 99%

How to win at online slots

Online slot machines are entirely random, making them a game of chance rather than skill. However, there are some things you can do to increase your chances of landing a winning line. The first thing to understand is not all slots are the same in terms of features. It usually pays well to choose games with a high RTP, so consider this while choosing an online slot machine.

Practice is another thing, especially knowing that there are free slot games in different Pennsylvania online casinos. This helps you understand the secrets of the game and bonus rounds. Lastly, ensure that you stick to your budget by setting a maximum before you start playing. If you reach the max amount, stop playing. Never wager an amount you can’t afford to lose.
