Brief History of Slot Machines

Slots emerged way back in 1895 in California. The emergence of slots games was linked to the famed Gold Rush at the time. The first slot machine game was known as the Liberty Bell. It was a 3-reel game that paid 50 cents (equivalent to approximately $15 today) if you landed three bells in a row.

While the original slot games were outlawed in 1902, fruit slots were invented about the same time to circumvent the legal hurdle. Fruity slots with lots of symbols remain popular even today. The 1960s marked the epitome of technology that enhanced the production of real and online slots. At the same time, the internet was gaining traction worldwide. The introduction of the Random Number Generator was particularly an important step forward into the future of slots we know today.

Slot machine games online have gained popularity in recent years to become one of the most played casino games ever invented. And as gaming technology advances, the future of online slot games can only get brighter.

Guide to Slot Machines Online: Gameplay, Themes, Terminology

Like any other casino game, you have played online, understanding online slot machine Singapore is the first step to playing your way to big winnings. And because gambling comes with risk, experience plays significance in cutting losses, especially when placing bets on any online slot game Singapore. First off, understanding the gameplay/game plan is the key to playing like an expert. Slots are developed around different themes, such as sports and war. And within each theme are a story and a game plan that punters must understand.

Next, understanding winning combinations in slot games before playing slots online is paramount. It goes beyond spinning the reels. Slots are controlled by mathematical algorithms that ensure that the system is not rigged and that every gambler has a fair chance of winning.

Let’s break it down into RTP, slot machine gameplay and terminologies to help you play online slots games like a professional.


Return to play, abbreviated as RTP, is a common terminology in slots. The RTP or payout percentage is the average winnings that a gambler earns from a slot machine wager. Before playing an online slot, gamblers are advised to check the RTP of a game to ensure it pays well above 96%. But if you are a beginner, it is never a bad idea to try out new online slots Singapore with a lower payout. Moreover, free online slot games should be a great starting point for a gambling novice looking to explore SG slots online.


Volatility is another popular term you will come across often when playing online slots machines. While RTP represents an estimated payout percentage in online slots machines, volatility denotes the frequency of winning and the payout size. The catch is that some SG online slots trigger winnings more often than others, so choosing the right game from the onset is important.

Volatility is categorized as low, medium and high. In this case, highly volatile slots pay rarely, and when they do, it is a lump sum. On the other hand, low volatility pays frequently but in small amounts. It means everything boils down to a player’s readiness to take a risk with big stakes or patience with smaller stakes.

Hit Frequency

Hit frequency is another significant term in online slot machines. It calculates a winning probability every time you hit the spin button. Say, if a hit frequency of online casino slot games is 30%, it means you are likely to win thrice in every ten spins, or at least 30% of the time.

Types of Online Slots

After understanding slot machine games online, the next step is exploring the variants of the game. Singapore online slot games come in a variety, and for a novice, it is always a good idea to start with online free slots. Before taking chances with a real money account, novice punters should experiment with free online slots. So, let’s explore the various types of online slots in Singapore below.

Classic Slots

Classic slots are games that use mechanical reels and have a straightforward paytable. Modern reference to classic slots is that they have three reels and have limited winning combinations. Most of these variants have a single payline.

Video Slots

From a technical standpoint, every slot machine online is a video slot. It is a digital world, and with thousands now playing casino games online, even free online slot machine games are video-oriented. Most video slots today have 20 paylines and five reels.

Progressive Slots

Progressive slots are definitive of cumulative jackpot prizes that one can win in a single bet. Note that a given percentage of every bet contributes to the ultimate jackpot prize. In a nutshell, the more players and the higher frequency of betting, the bigger the jackpot prize.

Multi-Payline and Multi-Reel Slots

Multi-payline slots constitute several paylines in a single slot. With more paylines, punters have more winning ways when they play slots. The amount of stake also varies from multi-payline to classic SG slot online. Some slots have more than 1,000 paylines, which is beyond the standard 20 paylines you find in most online slot Singapore platforms. And while typical slots have three reels, multi-reel slots have as many as 9 reels. More reels in online slots SG means players can have more winning combos.

VR Slots

VR or Virtual Reality slots are more like real/land-based slots. VR slots can only be played on VR casinos using VR headgear, without which you will not experience the thrill of playing online slot Singapore in a virtual reality environment.

Interactive Slots

Interactive or I-Slots starts with drawn-out cut scenes followed by a mini-game. The catch with I-Slots is that they add more excitement for a deeper level of experience when playing slot online Singapore.

Having explored different types of Singapore online slots games, let’s now turn to various features that make up a slot machine.

Free Spins

Free spins are a popular feature in any Singapore online slot. You will find free spins in both real money and free online slots games. And unless free spins are welcome offers, players must hit a certain combo of other slot features to trigger free spins.


Respins are features triggered by reaching a certain level in slot gameplay. In most cases, respins are triggered to give a gambler more winning ways. In most cases, you have to hit winning multipliers to trigger respins. They give you an added advantage, especially if you want to play slot machines online for free, even with a real money account.

Wild Symbols

Wild symbols are commonplace features in online slots machine Singapore. A wild symbol can replace any winning combo, but not the scatter in most games. Note that when playing slots game online Singapore, you will mostly target wild symbols for a high payout combo.
