Overview of Online Casino Games

Online casinos essentially recreate the experience of “brick and mortar” casino games. Virtualising and gamifying the casino experience to the constraints of your desktop or phone has many benefits for these establishments, one of them being that they can cram as much variety as possible into their virtual walls. Brick and mortar casinos lack this flexibility, because they unfortunately do have walls.

Let’s take a look at some games you will often find in these casinos.

Blackjack

Blackjack is a card-based game, the objective being that one must get as close to 21 as possible without exceeding 21. You must beat the dealer at the same game to win. Blackjack also has one of the lowest house edges in online casinos, often around 1%.

Slots

Slots are my personal favourite choice. Winning is based on RNG (random number generator) systems, meaning each spin is inherently different from the last. This ensures luck is always the ultimate provider of fortune. The RTP percentages in online slots typically range from 85% to 98%, varying by game and provider. Sometimes the same slot will have a different RTP at different casinos.

Craps

Craps has betting options with odds as low as 1.4% depending on the bet type. To play this game, a shooter (dealer) first rolls two dice, and you (the player) have to then bet on the outcome of this roll. There’s a multitude of variety here to bet on, which is where things get fun!

Roulette

Roulette is a prediction game where the player must guess where a tiny ball will land on a wheel: black or red? There are some clear differences in playing Roulette at a European casino compared to an American casino. This is important to note if you’re interested in playing at either.

European Roulette Tables

Key Features:

Single green zero (0)
37 numbers in total on the wheel (0-36)
House edge: 2.7%
Prevalence: Primarily found in Europe

American Roulette Tables

Key Features:

Two green zeros (0 and 00)
38 numbers in total on the wheel (0, 00, 1-36)
House edge: 5.26%
Prevalence: Primarily found in the United States of America

Odds vs Luck: Finding The Right Balance

While odds play a crucial role in any game, Lady Luck still has her say. Even the most carefully calculated bets can swing either way with the roll of a dice or spin of a wheel. That’s part of what keeps casino games exciting. But if you’re aiming to stretch your bankroll or walk away with more wins than losses, leaning into games with better odds gives you a real advantage. It’s not about removing the fun or the thrill, it’s about giving yourself the best shot when luck does show up. After all, it’s easier to win when the numbers are already working in your favour. The key for Irish players is to find that sweet spot: choosing games where the odds are on your side, while still leaving room for a bit of chance.

New Casinos Are Quietly Shifting the Odds

One exciting trend we’ve noticed in the Irish market is how some new online casinos are putting more emphasis on fairer odds. Some now offer blackjack games with lower house edges, roulette tables with better payout structures, or even slots that are audited for higher-than-average RTPs. They’re also tweaking promotions so that bonus spins and free bets are usable on higher-odds games. It’s worth keeping an eye on these changes, especially if you’re looking for that sweet spot between entertainment and value.

Responsible Gambling & Online Casino Games

As much as odds can seem to play a big part in the initial enticement of picking a game and playing a game, ensuring you are betting responsibly on these games is of utmost importance. You could feel like you’re on a winning streak, but chasing this win can often do more harm than good.

The gambler's fallacy is a common misconception in casinos, where people mistakenly believe that after a series of random occurrences (such as a coin repeatedly landing on heads), the opposite outcome is "due" to occur. However, each event is entirely independent, and the odds remain unchanged. This is important to keep in mind because it’s often easy to get swallowed up by this belief.

Our Expert’s Verdict

All in all, there’s a grand range of games that offer competitive odds at online casinos! The best, in my opinion, is blackjack. Whilst odds and variance are important, the best way to get a feel for these is by spending time at a casino you feel most comfortable in, which gives you a better gauge of how the games work, and also what your average returns are over more extended periods of time.

FAQs

How do I choose odds between different platforms? All of them offer good odds

Look for small differences that add up, even a slightly higher RTP or better payout on certain bets can make a difference over time. Also check if the platform offers games with lower house edges, fair game rules, and transparent info on RTP. If the odds are similar, go with the one that offers better bonuses, faster payouts, or a smoother experience.

Do live dealer games have better odds than virtual ones?

Both game types are great; it really just comes down to what you prefer! If you're into interacting with others and don't mind a bit of pressure, live dealer games are probably your best bet. But if you're looking for something relaxing, virtual table games are definitely the way to go.
