Yes, most casinos offer their games for free practice play. And here’s why: online casino games give you the chance to win cool rewards when you place real money bets as you play. However, playing a game without being fully aware of its mechanics and features can result in losses.

Playing in the free practice mode gives you the opportunity to get used to the game and understand its features before you spend money on it. You can play in this mode for as long as you like. However, you will not be able to cash out any of the winnings that you score in this mode.

For the longest time, all the online casino games were available for free practice play except for live casino games. Live casino games were always offered solely in the real money mode because when you opted to play for free, you blocked a seat at a table and thereby deprived a potential real money player the chance of playing and scoring wins. However, nowadays there are live casino software providers like Fazi who offer their games for free practice play too!

Among all the different types of online casino games available, the most popular are the slots. They are games of chance – you don’t need special skills to play them – and are played at a fair pace. Because they are the most popular, they form the biggest chunk of games in the library of all online casinos.

So which of the slots are the most popular, you may ask. That may be quite difficult to answer, because preferences vary from one player to another. However, if we go by sheer numbers alone, one of the most popular slots in the industry is Starburst from NetEnt.

The popularity that Starburst enjoys can be gauged by one simple fact – only now, 9 years since its launch, do you have a sequel/modified version in Starburst XXXtreme!

Starburst struck a chord right from its 2012 launch. The simple game play – 5 reels, 10 paylines, and the Expanding Starburst Wilds that trigger the sole bonus feature, a re-spin – and the maximum win of 50,000 coins were big hits among players!

Another popular slot is Gonzo’s Quest, also from NetEnt. The slot is themed on the adventures of the explorer Gonzalo Pizzaro, aka Gonzo, and his search for the Lost City of Gold, El Dorado. Launched earlier than Starburst, in 2011, the game has great graphics and animations. It gives you a maximum win of 37,500x your stake in the free spins round thanks to the avalanche multipliers of up to 15x!

Playing online slots is easy. The first step of course is to sign in to your casino account and then choose whether you want to play for free practice or for real money.

If you choose the free practice mode, the casino loads dummy credits into your account. Place your bets and hit the Spin button. You win if you are able to land the right grouping of symbols lands across the reels. If you are playing for real money, ensure that your account has adequate funds.

There are a few things you should keep in mind though:

1. Remember, online gambling is more like a recreational activity. Never look at it as a primary revenue generator.
2. The house always has the edge.
3. Do not get into panic mode and try to recover losses if you lose. Because that is the first step to gambling related problems like debt and addiction.
4. Slots are games of chance; so there is no system to bank on to guarantee more wins.
5. Of course, there are steps you can take to minimize losses, like bankroll management, for instance.

When you strip it down to the basics, all slots – online as well as land-based – work the same way: you place your bets. Hit the spin button and wait for the spinning reels to grind to a halt. You win if the right symbols land across a payline – or paylines – in the right order.

For online slots, the outcome – the sequence in which a set of symbols land across the reels – is determined by a random number generator (RNG). The RNG generates random number sequences at regular intervals of a few milliseconds continuously every time you hit the Spin button. This ensures complete randomness of game outcomes.

A progressive jackpot grows in size as the game progresses, without it being triggered. Once you hit the jackpot, it resets itself to a preset base value, called the seed value, and once again starts building up.

How does the jackpot build up? Each time a player places a bet on the game, a percentage of the wager is set aside to build the jackpot up, and the reset value too is collated from this percentage. The more the number of players playing the game, the faster and bigger the jackpot grows.

There are 3 types of jackpots:

Network online progressive jackpot: This jackpot is linked to a network of slots across casinos and therefore comes with a huge payout, because the number of players playing them and contributing to the jackpot is huge. Examples include the Mega Moolah series from Microgaming and games like Hall of Gods and Mega Fortune from NetEnt.
Local online progressive jackpot: These jackpots are linked across a series of games at an online casino. The jackpot value is not as high as what you see in a network progressive.
Standalone jackpot: This is a jackpot on a specific single slot that is not linked to any other slots at the online casino. It has a fixed payout value, because only wagers placed on this slot contribute to the jackpot. The jackpot value, therefore, is usually modest and on the smaller side.

There are quite a few online slots that feature a progressive jackpot. We list some of the big guns of the industry for you here.

Microgaming is the provider with the biggest selection of progressive jackpots. It has an entire series of Mega Moolah jackpots, including the original Mega Moolah game, Mega Moolah Goddess, Atlantean Treasures, Absolootly Mad, Fortunium Gold, Immortal Romance and Juicy Joker. Another collection from this provider is the Wowpot series, with games like 9 Blazing Diamonds, Book of Atem, Sisters of Oz and Poseidon: Ancient Fortunes.

There are a few big network progressive jackpots from NetEnt too, including games like Arabian Nights, Hall of Gods, Mega Fortune and Mega Fortune Dreams. Another jackpot that is from this provider, but slightly smaller, is Divine Fortune.

There are quite a few titles that can be considered among the most popular online slots games. We have already, in an earlier question, mentioned the 2 that can be considered the most popular – Starburst and Gonzo’s Quest from NetEnt.

Starburst now has a modified version – Starburst XXXtreme – while Gonzo’s Quest has 2 more titles now: Gonzo’s Quest Megaways and Gonzo’s Treasure Hunt.

There are quite a few other games that feature among the most popular titles nowadays.

These include, among others:

Thunderstruck II from Microgaming (and its variant, Thunderstruck: Wild Lightning)
Game of Thrones from Microgaming (and its variant Game of Thrones Power Stacks)
Elvis Frog in Vegas from BGaming
Book of Dead from Play ‘n Go
Storm Lords from Real Time Gaming (RTG)
Safari Sam 2 from BetSoft Gaming

One of the ways to determine which are the best online slots is to find out the ones that offer you the best shot at a win, and the one way to find this out is by taking a look at the Return To Player (RTP) value for each slot under consideration.

The RTP value lets you know how much a slot pays you back over time. A slot with a higher RTP value is likely to give you a better shot at a win.

Here are 5 slots with high RTP values:

Ugga Bugga: This Playtech slot has a RTP value of 99.1%!
Mega Joker: This NetEnt slot has a 99.0% RTP value!
Cosmic Quest: Mystery Planet: This NetEnt slot has a RTP value of 98.9%!
1429 Uncharted Seas: This slot from Thunderkick has a 98.6% RTP value!
Blood Suckers: This is a NetEnt slot with a RTP value of 98.0%

To be able to play at an online casino you must have a system with certain basic requirements met. This is important because online casinos come with high quality graphics and animations, and a system that doesn’t meet the requirements will not be able to deliver a good experience overall. For instance, slow internet speeds will cause lagging and impact overall game experience.

The following are the basic system requirements to be able to access online casino games:

RAM: 4GB
Processor: 1.6 GHz
Screen resolution: Minimum of 1024 x 768
Flash Player: 10.2 or higher
Internet speed: Minimum of 512 Kbps
