Getting started with online slots at Monster Casino

Sign up or log into your Monster Casino account

As an online slot player, the first thing you need to do is sign up for a Monster Casino account. Do you feel intimidated by this task as a beginner? Don’t worry. Our registration process is straightforward and can be completed in just a few easy steps. And if you’ve already signed up with us previously, you need to log into your Monster Casino account using your login details.

Select your preferred slot game

Once you have set up your casino account, the next thing to do is to choose and load your preferred slot game. Then you’ll be transferred to a gameplay screen featuring the slot reels, operating buttons and other information about the game.

Go through the game’s paytable

At this point, we recommend you go through the pay table of your chosen slot game. This will let you know how much each symbol is worth in the game. Also, it will help you get acquainted with the specific payout rules for the slot title.

Choose your bet size

After this, you must select your wager size and the number of paylines you wish to play. You can choose the ‘Max Bet’ option if you want all the paylines to remain active for that round.

Initiate the gameplay

Now, all you need to do is click the ‘Spin’ button to start playing. The paytable of the game will determine how much you will receive if you get a winning combination.

The different types of online slots

Back then, players could choose a few slot game categories, such as classic slots and one-arm bandits. Nevertheless, today's slot gaming options are more diverse and varied than ever before. Below are the main types of online slot games you can find on our website:

classic slots

Classic slots

Simply put, classic slots are digital versions of the original 20-century slot machines. Classic slots usually come with a 3x3 grid and are preferred by players who enjoy playing straightforward slot games. To win at these slot games, all you need to do is get a combination of three or more matching symbols on your reels.

Progressive Jackpot slots

Progressive Jackpot slots

These are highly-popular slot types in the online slot gaming world. This is because progressive slots come with a jackpot prize that increases every time players place a wager on these games. Also, the jackpot amount continues to rise until someone wins. As soon as the jackpot prize is won, its value resets and rises again.

3D slots

3D slots

3D slots are a relatively new entrant in the world of online casinos. As their name implies, these slot games offer a more engaging gaming experience by featuring top-notch graphics, high-quality animations and mesmerising soundtracks. Also, many 3D slots come with additional bonus features and have complex storylines for players to follow.

Multi-Payline slots

Multi-Payline slots

Players can play these slot games with an increased number of paylines and symbols. Depending on your chosen slot title, the number of paylines in multi-payline slots can range between 20 and 100. Furthermore, the paylines in these slot games can take multiple forms like vertical, diagonal or zigzag, making the overall gameplay more engaging and exciting.

VR slots

VR slots

VR slots are based on Virtual Reality technology. VR slot games immerse players in a virtual slot gaming environment that they can interact with using a VR headset. That way, players experience the same slot gaming ambience as they would have in a land-based gambling venue.

Video slots

Video slots

Video slots are computerised versions of 5-reel slot games that became popular in the late 20th century. But unlike their land-based counterparts, video slots come with several additional features, such as scatters and wilds. Also, many video slots have in-game bonus rounds triggered by landing the right combination of special symbols.

Top Slot Features to Check Out

At Monster Casino, our players can find several extra features, including re-spins, random wilds, and jackpot rounds. The exact function of these features varies from game to game, but they usually offer players additional ways to win. Below is a list of some of the most common slot features.

Random wilds feature

With the random wilds feature, the reels of your chosen slot game can see the appearance of wild symbols at any point during the gameplay. In most online slots, the random wilds feature can get triggered in both the base game and the bonus round.

Gamble feature

This is another exciting slot feature that can be found in some top online slot games. Here, players have the chance to multiply the amount they’ve won on a specific spin. As you’d guess, this feature gets activated when you get the required winning combination.

Respin feature

Starburst was the first online slot game to introduce this feature. Players don't have to pay for their next spin when the re-spin feature is triggered. In that way, they can improve their overall payout or try to get the required winning combination.

Tumbling reels

Tumbling reels are called dropping symbols or cascading reels. With tumbling reels, your winning symbols cease to be visible as soon as you hit a payout line. This, in turn, leads to other slot symbols taking the place of winning symbols. As such, you have another chance of forming a successful combination again.

Common slot symbols in online slots

Slot symbols are a highly significant aspect of online slot games. As a player, understanding the characteristics of different slot symbols ensures that you’re better informed about what to expect from the symbols featured in your chosen title. At our casino, we have the following types of symbols on slot machines.

Standard symbols

Standard symbols

Standard symbols are just regular symbols found in any online slot game. The function of these symbols is to offer a payout when you manage to get enough of them on your reels.

Wild Slots

Wild Slots

Wild symbols are a type of online slot symbols. They are unique in the sense that they can act as a substitute for other symbols (except scatters) in slot games. That way, players have a better chance of winning.

Scatter symbols

Scatter symbols

Scatter symbols are a prominent part of several top online slot games. Depending on your chosen slot title, scatter symbols can activate a free spin round or offer higher payouts. But note that some slot games can trigger both.

Bonus symbols

Bonus symbols

As their name implies, landing the required number of bonus symbols triggers an in-game bonus round. With bonus symbols, players stand a chance to collect extra prize rewards.
