Slot games

We love a good slot game here at CasinoTopsOnline, and we’re not alone, as they remain the most popular type of game among online casino fans. In fact, according to Statista, around 55% of online gamblers prefer online slots to any other form of online gambling.

Slots offer a tremendous variety of themes, cutting-edge graphics, and immersive sound effects. These games are packed with engaging perks like free spins, exciting bonus rounds, and the potential for massive payouts.

Slots are inherently easy to play, and their availability across multiple platforms, especially mobile devices, makes them accessible whether you’re playing at home or on the go. Reflecting this trend, the global online gambling market is projected to reach over $117.5 billion in 2025, with mobile play dominating the industry.

These games utilize various symbols, paylines, and reels. Progressive jackpots, in particular, create huge excitement as each spin adds to an ever-growing prize pool that one lucky player will eventually claim.

When assessing your potential for winning, slots typically have a Return to Player (RTP) percentage of 90–98%, meaning the casino's house edge is 2–10%. While strategic table games may offer lower house edges, slots provide unmatched simple fun and the thrill of large potential jackpots.

Types of slots you can find at online casinos

Online casinos offer a diverse and exciting range of slot machines, each providing a unique style of gameplay and potential for big wins. These are some of the most popular categories:

• Progressive Jackpot slots

• Megaways slots

• Video slots

• Classic slots

Importance of RTP and volatility

To choose the right slot, look past the theme and graphics and focus on two vital factors: Return To Player (RTP) and Volatility.

• RTP: This percentage represents the expected long-term payback to players. Aim for an RTP between 94% and 96%.

• Volatility: This measures the risk and win frequency. High-volatility slots offer large but rare wins, while low-volatility slots offer small, frequent payouts.

Knowing these crucial details allows you to select a game perfectly matched to your playing style and bankroll.

Table games

Table games attract players who love implementing a little skill and strategy in their gameplay. Let’s take a look at them in more detail:

Table game	What is it?	Why people like playing
♠️ Blackjack	Beat the dealer without exceeding 21	It offers one of the lowest house edges
🎡 Roulette	Bets are placed on a spinning wheel	It’s packed with thrilling action
🃏 Poker	A player-v-player card game	A mix of luck, psychology & strategy
🎲 Craps	A dice game	It’s a highly sociable game
⭕ Baccarat	Bet on the player, banker, or a tie	Easy to follow with a low house edge
🐉 Sic Bo	A dice game from China	Various betting options & payouts

For table games, the Return to Player (RTP) and house edge can vary significantly depending on the specific game and even the strategy employed.

• Blackjack: Can have a very low house edge (around 0.5%) if you play smart. Without a good strategy, it goes up.

• Baccarat: The house edge is low on Banker (around 1%) and Player (around 1.2%) bets. Avoid the Tie bet, as the house takes a much bigger cut there (around 14%).

• Roulette: European Roulette (one zero) is better for players, with a house edge of about 2.7%. American Roulette (two zeros) has a higher house edge of over 5%.

In general, many table games offer a lower house edge compared to slots, especially when played with a strategic approach. This means a higher potential return for players who take the time to learn the optimal strategies for games like blackjack and certain video poker variations (which can have RTPs over 99%).

Live dealer games

Live dealer games are an excellent way to bring the thrill of a real casino atmosphere into your living room, or even on the train ride home! Wherever you are, you’ll be able to interact with dealers in real time and play table games like live blackjack, live roulette, and baccarat.

Speciality games

Games like keno, bingo, and scratch cards add something different to the usual selection of games offered at online casinos. These games are simple and need less strategy, making them perfect for beginners or casual players.

Crash gambling

Crash gambling is one of the newer trends to hit the scene in recent years, and it’s particularly popular at crypto casinos. Crash games appeal to players who love the thrill of high-risk play, as you can bet on a rising multiplier and need to cash out before the game ‘crashes’.

Sweepstakes and social casino games

Sweepstakes casinos are a distinct form of online gambling where you can play a range of classics that you’d find in a ‘regular’ casino, like slots and table games. The difference is that no real money is spent on these games. Instead, virtual currencies are used, which are exclusive to sweepstakes casinos.

Which casino games should beginner players try first?

For beginners diving into online casinos, the best approach is starting with user-friendly games based purely on chance, which require no strategy.

• Online Slots: These are the simplest starting point. Just hit 'spin' and watch the reels go! Beginners should focus on slots with higher RTP percentages (94-96%) and low volatility for more frequent, smaller wins.

• Online Roulette: A classic choice, particularly when sticking to simple outside bets (like betting on Red/Black or Odd/Even). The rules are straightforward, making for an exciting, gentle introduction to table games.

• Baccarat: Though often perceived as high-roller, the basic gameplay is incredibly simple: just bet on the Player, the Banker, or a Tie. The dealer handles all the complex rules automatically.

These three games offer a smooth and fun introduction to the online casino experience.

Mobile-optimised casino games: perfect on-the-go

For the best experience while playing on your smartphone or tablet, mobile-optimized casino games are essential. Developers now prioritize a mobile-first design to ensure seamless, engaging gameplay, even on smaller screens.

• Online Slots: Slots excel on mobile, featuring simple tap-to-spin actions, intuitive layouts, and scalable graphics that look great in portrait mode.

• Live Dealer Games: Once complex, live casino lobbies are now highly optimized, bringing the interactive thrill of live blackjack and live roulette to your hands with clear video streaming and simplified betting interfaces.

• Instant Win Games: Casual titles like scratch cards and Keno are inherently mobile-friendly due to their simplicity and minimal on-screen elements.

• Table Games: Popular games like Blackjack and Roulette adapt well, utilizing large buttons and clean card displays for easy touch control.

How are casino game outcomes determined?

To ensure fairness in casino games, a few tools are used to make sure that players are getting an honest and transparent playing experience. Methods include the use of modern technology as well as more traditional tech. Here are some examples:

Random Number Generators

Random Number Generators (RNGs) are used in slots and digital table games to make sure that every spin is truly random and not fixed.

Probabilities

When it comes to casino games like roulette wheels or card games, probability is a part of the gaming mechanics. An example of this can be seen in European roulette, where the wheel will have 37 slots. The numbers range from 0-36, which means that whatever number you choose in that range, your chance of winning is 1 in 37.

Strategies

While some casino games are based on pure luck, a few of them, like poker and blackjack, require strategy to improve your chances of winning. These games can be played in a way that gives players an advantage — that is, if you know the right techniques, of course!

Live dealers

Live dealer games use a deck of cards in real time, as well as roulette wheels, dice, etc, much like what you’d find at a physical casino. Effectively, this means you’ll get the same level of transparency.

Playing for real money vs. free demo game version

There are many benefits to playing demos compared to playing for real money. These free play options can elevate gameplay without affecting your funds. 

Most demos can be accessed when hovering over certain game tiles or through the small ellipsis (...) button in the corner of the tile. Playing casino games for free is great for:

This all comes down to personal preference and what suits your needs. To get the very best out of your gaming experience, here are some things you might want to consider:

Minimum and maximum bets

Think about your budget first, and then stick to that amount to ensure a smooth and stress-free gaming experience.

Themes and graphics

Picking a game with a theme that you’re drawn to will enhance your experience further.

For example, if you love ancient Egypt, try something like Book of Dead for a theme full of mystic wonder. Or if you’re into space and you’re captivated by celestial graphics and shiny jewels, Starburst could be the perfect game for you. There’s truly a slot game for everyone where you can choose categories like action, adventure, fantasy or even titles based on popular TV shows and movies.

RTP and volatility

Looking at RTP percentages and volatility are important factors to ensure that you get the most out of your gaming. They can help you to assess your level of risk beforehand.

Luck vs. strategy

Decide whether you want a game based on luck or whether you want to try your hand at some strategic moves to put your newly found skills into practice.

Jackpots and house edge

If you want to boost your winning potential, check out the games that have larger jackpots or a lower house edge to maximise your chances.

AI personalization

Leverage AI-driven personalization features offered by casinos, which use your history to recommend tailor-made games and specific bonuses.
