Best Casino Games For Beginners

If you’re new to online casinos, you may ask yourself, “which is the best casino game to play?”

The answer to this comes down to personal preference. For example, some may be drawn to playing popular table games like roulette, while others may like the look of online video slots.

Online Slots

Here at 666 Casino, we have a vast selection of online slots, from the famous Book of Dead by Play’n GO to the latest fishing spectacular, Big Bass Splash by Pragmatic Play.

Some of the best casino games for beginners could fall into the slots or classic slots category. Slots are often deemed some of the best games for beginners due to their straightforward playability, and classic slot games tend to lack any complicated features.

Online Classic 3-Reel slots, in particular, usually don’t offer any bonus rounds. So it may help to think of them like traditional slot games on land-based casino floors. 

However, despite their old-fashioned look, classic slots are still extremely popular among players. Game providers are constantly updating old games and creating new ones. A good example is the Joker’s Jewels slot, part of Pragmatic Play’s Drops and Wins Promotion.

Besides Classic 3-Reel and 5-Reel games, there are thousands of other online slots to choose from!

There are slots that offer different themes such as the luck of the Irish, ancient Egypt, animals, fishing or fruit-themed slots, to name a few. 

There are also online games that offer different game mechanics. For instance, Megaways slots, Cluster Pays, Scatter Pays, Cascading Reels, Pay Both Ways and more!

Some of the best online slots can offer various entertaining bonus features like Free Spins, Hold and Spin, Respins, Super Free Spins, Link and Win, Progressive Jackpots and WowPot Jackpots.

Each online slot game can offer something different. If you find a video slot you’re interested in playing and want to learn more about it, you can check out 666 Casino’s detailed ‘Game Reviews’ section. You can also load the slot game and read the game’s paytable or rules for more information.

However, despite the slot game you may choose, all games typically play out similarly. You simply set your preferred wager, hit the Spin button and wait for the reels to come to a stop. 

Winning combinations are usually formed by landing a number of matching symbols across a valid payline. The more identical symbols you land in a single spin, the bigger the potential payout!

However, this may change from slot to slot, so reading the paytable before spinning may be best. It’s also worth noting that all slots offered by licensed and regulated UK casinos, such as 666 Casino, run on a Random Number Generator (RNG). This ensures all slot results are random and unpredictable, making it fair for all players.

Roulette

Roulette could be another excellent option for beginners to try. It is one of the most popular casino games in the UK. This is because it can be relatively easy to play. You simply place your bets on numbers ranging from 0-36. These bets may be on a single number, a group or row of numbers, red/black, odd/even or high/low.

Then, the dealer, also known as the croupier, tosses a ball onto a spinning wheel and waits for the ball to land on a random number. If it lands on your number, you win!

Single-number bets can pay 35:1, whereas bets on red/black or odd/even can pay 1:1.

If online roulette is your go-to game, then you won’t fail to be impressed with the huge array of roulette tables here at 666 Casino, from the classic 20p Roulette, with its automated RNG software, to the new Lightning Roulette, with boosted payouts on select numbers every time the wheel spins. We’ve got something for everyone!

Popular Slot Games To Play Online

With such a wide range of online slot games available to play, it can be challenging to decide where to start. Many slot enthusiasts tend to search for the most popular slot games, as these games can lead to a high number of spins being played, potentially leading to more chances for a Jackpot to hit!

If you want to play some of the UK’s top slot games online, 666 Casino is the place to be!

We’ve compiled a short list of some of our most popular slot games, all of which offer stunning graphics and interactive gameplay.

1. Big Bass Bonanza

Big Bass Bonanza is a popular video slot brought to you by the creative team at Pragmatic Play. It’s a game that’s part of Pragmatic’s unique Drops & Wins promotion, and players can choose whether to opt-in when the slot loads.

Stakes range from £0.10 up to £70 a spin at 666 Casino, making it a top slot game among many players. It also offers Fish Money Symbols that can land with random values of 2x up to a whopping 2,000x your bet!

Big Bass Bonanza offers a Free Spins bonus that can be unlocked by landing 3+ scatters in a single spin.

Additionally, Fisherman Wilds can appear during the bonus round, and every 4th Wild collected can trigger an additional 10 extra spins and increases the multiplier, which can potentially reach up to a maximum of 10x!

Offering a fun fishing theme, Money Symbols and a Free Spins round with possible retriggers, it’s easy to see why Big Bass Bonanza has made it to the top of our list of most popular slot games!

2. Book of Dead

Book of Dead is a fun video slot from Play’n GO, offering potential Free Spins with a random Expanding Symbol and a maximum win of up to 5,000x your stake!

It plays out on a 5-reel, 3-row grid with 10 adjustable paylines, and bets range from £0.20 up to £10 a spin.

This top online slot also has a Tomb Scatter symbol that acts as a Wild. So, it can replace any regular symbol, and it can also award wins if 3, 4 or 5 land in a single spin!

Landing 3+ scatters will also unlock the Free Spins bonus round and win you 10 Free Spins. If activated, a Special Expanding Symbol will be randomly chosen before the bonus round begins. If the selected symbol lands as part of a winning combination, it can expand to fill up an entire reel!

The best part is, Expanded symbols do not need to land adjacent to each other to form a winning combo.

If you manage to land an additional 3 scatters during the Free Spins bonus round, you will retrigger the feature and win 10 extra spins!

It’s no wonder this ancient-Egyptian-themed slot has made it onto our most popular online slots list.

3. Rainbow Riches Megaways

Brought to you by Barcrest and Light & Wonder (formerly known as SG Games), the Rainbow Riches Megaways slot offers 324 – 117,649 ways to win and a top potential prize worth up to a golden 12,500x your wager!

If you’re a fan of the famous Rainbow Riches series, this slot could make it onto your favourites list!

Not only does it offer a massive max win, but it also comes with a variety of features such as Cascading Wins, a Super Gems Bonus, a Free Spins Bonus with possible retriggers and an Unlimited Win Multiplier! That’s right, Unlimited – something that’s quite unique in the world of online slots.

Land 4 pot symbols to unlock the Free Spins Bonus and win 12 Free Spins. However, if you land more than 4 scatters, you can win an extra 5 Spins for each additional symbol!

4. Fire Joker

Fire Joker is a Classic 3-Reel slot with 5 paylines from Play’n GO. Winning combinations can be formed by landing 3 matching symbols, from left to right, across a win line.

The Fire Joker represents the Wild in this slot game, and it can replace any regular symbol.

Additionally, if you land stacked symbols on any 2 reels and it results in a non-winning spin, you win another chance with a Respin of Fire! If activated, the stacked symbols will lock in place while the others respin.

If you fill all the reels with the same symbol, you can take a spin on the Wheel of Multipliers, where your potential win can apply to a random multiplier of up to 10x your wager!

So, if you’re a fan of classic slots with limited features, consider giving Fire Joker a spin! 

5. Big Fishing Fortune

Inspired Gaming created one of the best fishing-themed slots, Big Fishing Fortune. Played across a 5-reel, 3-row grid, this game offers a top potential prize worth up to 1,500x your stake!

Bets range from £0.20 up to £100 per spin at 666 Casino, making it a favourite among beginners and experienced slot players. 

Regular symbols that can appear on the reels include a variety of fish, which represent the Mixed Pays. This means that they can award wins if they land in any successful combination. There are also the usually low-paying card royals A-10, a speedboat, fishing pole, tackle box and lifesaver ring.

Big Fishing Fortune also offers a Bonus Game that can be triggered by landing 3+ bonus symbols in a single spin. This will then activate a Match 3 game where you can potentially win multipliers reaching up to 100x!

Once you reveal 3 matching tiles, you then start the Free Spins round with your corresponding value on the Big Fish. During the bonus, you also get unlimited free spins until the Big Fish is caught!
