Online Slot Terms Explained


Reels are the vertical columns on slot machines that you spin once a wager has been placed. Symbols will land on them randomly to make winning combinations. The majority of online slots have 5 reels, although some will have more, some less. Many classic slots have 4 reels, 3 reels, or even just a single reel. Modern slot games, on the other hand, can often have 6, 7 or sometimes even more reels. A higher number of reels will not increase a player’s chances of winning, however. The likelihood that you will win some cash depends on an entirely different set of factors.

Bet amounts

The money you play on every spin is known as the bet amount. This quantity can be set manually through the ‘coin value’ and ‘coin level’ functions in the console of the slot game. The amount you’re permitted to bet at any one time can vary hugely from game to game, with wagering amounts starting as low as ₹5 and going all the way up to ₹5,000. If you feel like going all in, some online slots have a ‘max bet’ feature, which lets you increase your bet to the maximum just before you spin.


These vertical or horizontal lines, also known as win lines or bet lines, will pay out a fixed winning sum of money when certain winning combinations land on them. Paylines on most online slots pay from left to right, while some pay both ways. Usually, a player sets the number of paylines that will be active on the reels of a game, which will determine the size of their bet. There are, however, slots where the paylines are fixed.


A slot game’s paytable lists all the possible payouts that can be won depending on the combination of symbols a player lands. Normally, these amounts are stated as a multiple of a player’s wager.


In a slot game, the player spins the reels by clicking on the SPIN or PLAY button. Some online slots have an autoplay or autospin feature, which, when activated, will spin the reels a predetermined number of times, or until a predetermined amount of money has been spent.

Slot Terms for More Advanced Players

The slot terms we’ve looked at so far have been fairly straightforward to understand, but now it’s time to turn our attention to the more interesting features found in online slots. Look out for these terms next time you’re playing a slot game, because each of the features they describe can make a big difference to your winning potential.


With the exception of scatter symbols, wilds are able to substitute for all other symbols on a payline. Landing wild symbols on the reels means the chances of you getting a winning combination are increased, so they’re a hugely advantageous feature of slot games in general. You’ll come across a variety of wilds in slot games, including stacked wilds, sticky wilds, random wilds, and moving wilds. While each of these types of wilds will have a slightly different role, they all have the same primary function of substituting for other symbols.

Free spins

In online slots, free spins are awarded to a player at no extra cost. They can be triggered within a game in a number of ways and are often a feature of bonus rounds. Managing to retrigger free spins can lead to even bigger wins, particularly if these are combined with stacked wilds and multipliers. The number of free spins you can receive will depend on various factors within the slot game. Although, whether you get 5 or 50, they’re free so always a bonus in that regard.


Multipliers in online slots will boost your payout by a fixed number (2x, 4x, 6x, for example), and in some instances it’s possible to get a multiplier of up to 1000x your stake! You’ll sometimes find in-game free spins rounds that include multipliers, or wild symbols that also function as multipliers. Multipliers are a great feature because they increase your bet value even though you’ve not wagered anything extra.

Advanced autoplay

If you prefer not to be constantly spinning manually, you can instead use the advanced autospin or autoplay functions. These let you set the reels to spin automatically for a predetermined number of spins, or until a fixed amount of money has been used on spins. So, you can relax and simply watch the as the reels turn and the game plays out.

There are many more features in online slots that can really enhance your slot gaming experience, not least the various bonus offerings you’re likely to come across. Take a look at our guide to Bonus Slots to find out more about slot bonuses.

Three Commonly Misunderstood Slot Terms

Less familiar to most of us who play online slots are the terms below. These obscure terminologies can confuse even experienced players sometimes, but, in all honesty, you really don’t need to know or understand them to play and enjoy a slot game. Having said that, if you’ve always wondered what exactly these terms do mean, read on to find out more.

Hit frequency

The hit frequency is the likelihood that each spin in an online slot game will result in a winning combination. Normally stated as a percentage, the number will determine which games have a low and which have a high hit frequency. The higher the percentage, the more chance you have of winning over a period of time.

Return to player (RTP) or payback rate

The term RTP (return to player) refers to the percentage of all money wagered on a slot that a player can expect to get back over time. The RTP will vary depending on a slot game’s features, and the higher the RTP the more likely it is that a player will win back a larger share of the money they have already bet.


The ‘volatility’ is an indication of how often and how much you’re likely to win on a slot game. Online slots with a high volatility will usually pay out larger sums of money but less often, which means you’ll be waiting longer for a win, although it will probably be bigger. On the other side of this are the low volatility slots, which will pay out more regularly, but the winning amounts will be smaller.

Top Online Slots India Edition

If you’ve ever heard online slots referred to as Indian Slots or ‘India-friendly slots’, you may be wondering what exactly that means. This can be describing slots available to an Indian audience (as opposed to slots only available outside Indian markets) or simply online slots that are particularly popular with players in India. Starburst, Jungle Jim, Ecuador Gold and Thunderstruck II are all favourites among online casino players in India, and for this reason can be called Indian slots.
