We’ve already talked about the importance of checking which game providers an online casino partners with, but it’s just as crucial to see what specific games they offer. If you’re new to the scene and unsure where to start, don’t worry, we’ve got you covered! Here’s a list of what we think are the best online casino games to kick off your adventure:

Types of Casino Games
There are many types of online casino games, but the main categories include table games, online slots and, a relatively new edition, live game shows. Let’s start off with a run-through of the top casino table games.
Casino Table Games
Online Roulette
Online roulette, which includes both Random Number Generated (RNG) and Live Roulette variants, ranks among the most popular online table casino games favoured by players. With the potential for significant payouts due to its’ high RTP, particularly when betting on a specific number, which pays 35 to 1, the excitement and anticipation surrounding the landing of the roulette ball have contributed to its’ widespread appeal.
The leading online casinos often distinguish themselves by offering a vast range of roulette games. Some of the most popular titles include:
- Immersive Roulette
- Lightning Roulette
- XXXtreme Lightning Roulette
- Mega Fire Blaze Roulette
- Red Door Roulette
- 20p Roulette
- Instant Roulette
You will find most, if not all the above roulette games, at our recommended online casinos.
Online Blackjack
Like online roulette, online blackjack is available in both Random Number Generated (RNG) and live dealer formats. Players are drawn to blackjack not only for its excitement but also for the strategic elements it involves, such as basic strategy and card counting. These techniques enable players to make informed decisions, effectively reducing the house edge and enhancing their chances of winning.
In blackjack, understanding when to hit, stand, double down, or split pairs can significantly influence the outcome of the game. The blend of skill and chance makes it appealing to both new and experienced gamblers, thus positioning itself as a favourite among casino players.
Some of the best blackjack games include:
• Lightning Blackjack
• Classic Live Blackjack
• Speed Blackjack
• Terminator Blackjack
Play online blackjack games at our suggested online casinos.
Online Slots
Online slots are a pillar of the online casino landscape. Often regarded as the most popular variant of casino games, online slots account for the majority of game titles available at online casinos, with many platforms featuring thousands of titles to choose from. Their diverse themes can include fish, demons, wizards and leprechauns to name a few plus engaging graphics, and varying gameplay mechanics such as megaways slots help cater to a wide range of player preferences, ensuring that there is something for everyone.
Our top selection of online slots include:
• Big Bass Splash
• Fishin’ Frenzy
• Legacy of Dead
• Eye of Horus
• Immortal Romance
All of the online casinos we recommend feature a strong selection of popular online slots, many updated daily.
Live Game Shows
Live casino game shows are interactive gaming experiences that blend traditional casino elements with the excitement of fan-favourite game shows. In these formats, players participate in live-streamed games hosted by real dealers or presenters, offering real-time interaction and engagement. Crazy Time is the most recognised live game show, developed by Evolution, but there are a variety of other games that have also emerged from the market.
Popular Live Game Shows include:
• Crazy Time
• Lightning Storm Live
• Monopoly Live
• Dream catcher
• Adventures Beyond Wonderland Live

Safe and Secure Online Casinos
The primary factors that determine the safety of an online casino site are licensing and regulation. While many players may overlook this aspect, it is crucial when selecting an online casino. Legally, casinos must be licensed by a regulatory body to operate transparently and compliantly. This licensing ensures that players have recourse in the event of any unfair or illicit practices.
Any casino you choose to engage with should be licensed by an external authority, providing the best protection for your money. In the UK, the UK Gambling Commission (UKGC) is the sole authority responsible for licensing casinos that cater to British players. However, many online casinos are internationally based and may hold licenses from various jurisdictions, often for tax and compliance reasons.
Regardless of the jurisdiction, it is essential to play with a licensed operator and verify any information on the casino’s own website. Rest assured, every UK online casino that we’ve listed on this site is licensed and regulated by the UK Gambling Commission.
Reputation is another vital thing to consider. Researching casino reviews and feedback from other players can reveal important insights; for example, some casinos may have strong marketing but poor reviews, while others might be less visible yet enjoy loyal player bases. Conducting due diligence is essential, especially when dealing with anonymous online casino promoters. Fortunately, here at SmashCasinos.com we have already done the research for you, ensuring that you can feel confident joining any of the UK casino sites we promote.
NO NEED TO WORRY, EVERY UK ONLINE CASINO LISTED ON THIS SITE IS LICENSED AND REGULATED BY THE UK GAMBLING COMMISSION.

Online Casinos FAQ
To keep this answer short and sweet, yes its is 100% legal in the UK to join and play at an online casino.
NO, online casinos are not rigged. Why would a casino with a house edge want to rig the casino games? Casinos already have an advantage and there is no need to rig or alter to outcomes. If you join a UK Gambling Commission licensed and regulated casino you can be assured of no foul play.
Of course, you can win money in online casinos! If you were not able to win why would anyone play? As with all casino games, the casino has the house edge meaning in the long term, the casino will always win, however, this does not mean that in the short term you cannot have a lucky streak and win a large sum of money. This is what generates the excitement of playing online casino games, you never know when the next big win is looming.
In theory, if you look at the RTP slots should provide you with the best chance. Because the game plays out on its own it largely doesn’t require any skill or experience to increase your chances of winning. Every spin is independent of another one, but with casino games the player can make mistakes or not play the odds as perfectly as a seasoned player and this will also swing the advantage further towards the casino. Ultimately though gambling has to be fun and always within limits, only bet what you can afford to lose and play what gives you the most enjoyment. For us at SmashCasinos that is probably Crazy Time.
