Online slots are undoubtedly the most popular games at every online casino. Thanks to the fact that they have a simple gameplay and feature tons of bonuses that can lead you to massive winnings, it is easy to conclude why so many players from around the world are fond of them.

When choosing a slot that fits your personal preferences, you need to consider a few matters. That includes the slot’s volatility, Return to Player rate, the provider that created it, as well as the topic that we are going to discuss in this article – slot bonuses.

Basically, there are two types of slot bonuses – casino bonuses and in-game bonuses. We are going to take a deeper look into both of these types and allow you to get familiar with them. Let’s start breaking down the details.

Casino Bonuses

First off, we have casino bonuses, which can be a deposit or no deposit offers that are applicable on slots. To claim these, you need to be a registered player at a licensed and regulated online casino that utilizes the latest SSL encryption software to keep you secure while you enjoy the games.

Of course, choosing the best casino site is not always an easy task as there are quite a few features that you need to check. Luckily, there are expert platforms that do the hard work for you. Well-established sites such as scan the Internet and test all online casinos to determine which are the best and they can be of massive help, which is why it’s worth checking them out.

As for the applicable bonuses, you can use free spins, welcome offers, reload bonuses and loyalty bonuses. All of them come with a few terms and conditions that you need to adhere to. That includes minimum deposit, eligible games, eligible payment methods, market restrictions, wagering requirements, bonus validity period, etc.

Before you can withdraw any winnings made with the bonus, you must complete all T&Cs, especially wagering requirements. They signify the amount that you need to wager before reaping the benefits o the bonus.

Let’s say that you want to claim a welcome offer whose minimum deposit is $10 and wagerings are set at x50. That means that in total, you must wager $500 (deposit amount multiplied by wagering requirements) to withdraw winnings from the bonus, and it must be done while the bonus is valid.

In-Game Bonuses

What makes online slots so entertaining and dynamic is the fact that they also include in-game bonuses that can be of massive help to you. Let’s start symbol bonuses.

The Wild symbol usually substitutes regular symbols in the game and helps you form winning combinations. Expanding symbols expand on the reels and make it easier to form a win, whereas Mystery symbols are random regular symbols that appear and can be of contribution to the win.

But that’s not all. Online slots also feature the following bonuses:

  • Free spins
  • Bonus rounds
  • Progressive jackpots
  • Payline mechanics
  • Buy bonus
  • Cascading reels
  • Multipliers

During bonus rounds, you can receive extra spins or cash bonuses. Speaking of extra spins, free spins are by far the most popular in-game bonus. In most cases, they are triggered when you land a certain number of Scatter/Bonus symbols on the reels.

Progressive jackpots are the favourite in-game feature of high-rollers. They can lead to rewards that exceed $1 million. In most cases, they can be won in a bonus round where you have a special grid. Your task is to uncover 3 matching jackpots. Most commonly, progressive jackpots are divided into four levels – Mini, Minor, Major and Grand.

Payline mechanics are a rather new feature by online slots. They were developed by providers to make the gameplay far more dynamic and entertaining. The three most popular mechanics:

  • Megaways
  • Cluster Pays
  • Infinity Reels

The Megaways feature was developed by Big Time Gaming and thanks to it, the number of paylines changes on each spin and it can go as high as 117,649. Cluster Pays was developed by NetEnt and this is a rather unconventional payline system. Instead of forming wins from left to right and right to left, wins here are formed by making clusters of at least 5 matching symbols.

Finally, the Infinity Reels feature constantly increases the number of paylines as a reel is added with each win that you generate in the slot.

Speaking of reels, cascading reels is an in-game bonus in which symbols that trigger wins disappear and the ones above them dropdown. Most commonly, each cascading win comes with a win multiplier. Finally, the buy bonus feature allows you to purchase a certain in-game bonus in the slot.
