What is a mobile slot?

A slot machine is a gambling game that uses a combination of symbols on reels to decide winnings. It is the most popular game in both land-based and online casinos. The idea behind the game started around 1891 in New York when Sittman and Pitt developed a machine that could be spun to display cards randomly.

When the machine’s lever is pulled, it spins the card, and players will hope to get good hands which can earn them free beer or cigarettes. However, today’s slot games is much complex in features but simpler to play. You don’t have to pull any lever. You only need to press a button or, better still, click on a button. Instead of spinning cards, modern slot machines use Random Number Generators (RNG)to decide the outcome of each spin.

While slot machines are still available in brick-and-mortar casinos, most players now play online slots game on their mobile devices. A mobile slot consists of reels on which different symbols can fall. When you click on the spin button, the symbols will fall on the reels randomly. Winning is determined if a certain number of matching symbols fall on a pay line. A payline can be a horizontal line, vertical line, or any other shape specified in the game design.

The game uses RNG to determine the symbol that will fall on each reel. A Random Number Generator is a computer program that randomly generates numbers without referring to the previous action. That means each spin is unique, and the outcome does not in any way depend on the previous outcome.  Mobile slots are easy to play and full of fun. You can also win real cash. Because each spin takes a very short time, you can easily set the game to auto spins and watch as the computer spins for you.

Basic terms and Guidelines you need to know before Playing Online Slots Game

Playing slots games might seem very straightforward, but this is only the case if you understand all the terms and guidelines. What this means is that to get the best experience,  it is important to understand the basic terms and guidelines of the game. Although guidelines may vary slightly, the idea is almost the same in all slot machines. It is always good to go through the identity casino menu important info before playing.

If you are a beginner, you will want to read the guideline of your chosen game. Even though the descriptions and guidelines are written for beginners, many casinos will assume that you understand the basics. Hence, you should get familiar with the terms casinos use before attempting to play. Here we will explain some common terms used in a slot game.


Paytable is a table that shows all possible combinations that can make you win and the amount you will win for each winning combination per unit stake. The paytable will show the amount you will win for a symbol if you land three of the symbols on a payline per coin you staked. It will tell how much your winning will be if you land four of the symbol. If they are five, six until the maximum, you can win from the symbol. This will be stated for all winning symbols.


A payline is a line on the reels of a slot game on which you can win if you land matching symbols along the line. It can be a horizontal, vertical, or even zigzag line. There are usually many paylines on a slot game. The more the number of reels, the more the number of paylines.

Minimum and maximum bets

There is usually a maximum amount you can win from a single spin of a slot game. This makes the game developer set a maximum bet you can place. However, there is also a minimum amount you can place on a payline. This can be as low as 0.1 coins and as high as 100 or more. Free spins in most slots games usually have a value equivalent to the minimum bet.

Take advantage of the game bonuses

Casino games were designed to give returns to the house. Therefore, more people will lose than those that will win. Even though it is a game of luck and you can be in any category, casino bonuses will always put you ahead before making your first spin. Hence, a deposit match bonus and free spins can be beneficial to you. However, you must consider the max bonus available and the credit wagering requirement, i.e., the amount you must stake before you can transfer the winnings to your cashable account.

You must also understand that casino game wagering contribution varies. Hence you must know the specific game stake contribution and the games bonuses can be used for. All these are important before accepting any bonus offer. In addition to the normal bonuses you get from casinos, some slot games come attached with in-game bonuses. These bonuses can help you win more in the game and are usually in the bonus rounds. In most cases, the bonus may be a free spins round, or a wild multiplier, among others. Using them properly can be the deciding factor when you play. Make sure you read the paytable to learn about the bonus in each slot game and how to use them before you play.

What is the Difference between Wild Symbols and Scatter Symbols

Both wild and scatter symbols appear to increase your chances of winning but in different ways. A wild symbol is a symbol in slots games that can transform into any other symbol to give you a winning combination. The only symbol it cannot transform to is the scatter symbol. On the other hand, the Scatter symbol appears to trigger a bonus round, free spin, or other bonus features. Many slot games have both scatter and wild symbols, while some have only one of the two. Nonetheless, both of these symbols can drastically alter your experience in a slot game and help you win more.

Wild Symbols

Wild symbols transform into any symbol in a slot game to produce a winning combination. If you need a minimum of three matching symbols to win but have two matching symbols and a wild between them, the wild will transform to the matching symbols, making you win. There are various types of wilds, each performing different functions asides from the basic function of transforming or replacing other symbols. For instance, some wilds stay glued to one position, and they are called Sticky Wilds, Some can shift position as you spin, and are known as Spreading Wilds. Other types of popular wild symbols include Expanding Wilds, Multiplier Wilds, Duplicating Wilds, Colossal Wilds, Random Wilds, etc. Make sure you have a look at the slots paytable so you know which one to expect when you play a mobile slot game.

Scatter Symbols

Scatter symbols appear on a slot game to activate bonus features. These features may include a bonus round or free spins. You may need more than one scatter symbol before you can activate the bonus feature. Apart from the bonus features, some games also allocate winnings to the appearance of scatter symbols.

Mobile Slot Games Jackpot

One of the most important genres of slot games is the jackpot. This allows you to win a huge amount of money. Slots game jackpots can be a fixed jackpot with a fixed amount of winning or a progressive jackpot that increases in value as more people bet on the game. You will likely find jackpot games in any mobile casino you register with. Jackpots are usually won during free spins round.

However, it is also possible to win a jackpot during a conventional spin. In some mobile casinos, games played on jackpots are not included or may not contribute 100 percent to the bonus credit wagering requirement. Some games do not even contribute at all to the credit wagering requirement. Hence it would be best if you considered the specific game stake contribution of the jackpot so that you won’t be disappointed when you want to transfer winnings to your cashable account.

Progressive Mega Slots Jackpot

A progressive Mega Slots Jackpot is a jackpot game in which a certain percentage of every bet on the game across all casinos is contributed to the jackpot pool. As more people play the game, the jackpot value increases until it is won. The accumulated amount of progressive jackpots could be millions and more. This figure is usually displayed on a counter that can be viewed by anyone, and once a player wins, the figure resets and starts from scratch.

Because of the large number of people contributing to the pool, it usually involves a huge amount of winnings. Several people have won millions of dollars from popular progressive jackpots in the past. Today, Mega Moolah has paid out the highest in any progressive jackpot game and is still changing the lives of players everywhere.

Free Spins

Free spins can be part of a slot game or given by an online casino as a bonus. Many casinos usually include promotional free spins in their welcome package to new players. However, free spins given as a bonus by casinos usually come with a bonus credit wagering requirement.

Notwithstanding, there are also no wagering free spins. Bonus can be used to play specific games or all slot games subject to the bonus conditions and the promotional terms and conditions.

If you received a first deposit bonus together with free spins, you must meet the wagering requirement of the welcome bonus as well as of the winnings from the free spins. Many slot games also have free spin rounds. This may be activated when you land the required number of scatter symbols. The free spin round will allow you to spin at no cost. Winnings from these spins are not subjected to any wagering requirement.

No Deposit Mobile Slots

No deposit mobile slots game bonuses are bonuses you earn from an online casino upon completing registration and verification of your account. It may be in the form of cash in your bonus account or promotional free spins. Unlike a first deposit match bonus, no deposit bonuses do not require any deposit before you can claim them.

However, the max bonus available is usually low, and you may only be able to use it to play a few slot games. Also, winnings from bonus credit are usually subjected to stringent wagering conditions before you can transfer the winnings to your cashable account. There is also a limit to winnings you can earn subject to the bonus conditions. Notwithstanding, you will be playing a slot game for real money without taking any risk.
