How Awareness Improves Gambling Outcomes


If games online look like good entertainment, there are a few key concepts you should comprehend and memorize before proceeding to gambling websites. By understanding these core concepts, you’ll better understand the gambling process and be better equipped to make smart, informed decisions. So, if you strive for the best chance of winning in an online casino like N1 Casino Greece, take some time to learn about these key concepts first.

Key Online Casino Concepts You Should Know

Here is a short list of the main online gambling concepts you might want to study before taking your first steps in gambling. Your knowledge of them will facilitate your navigation across the huge gambling industry.

House edge


This term is used in gambling to describe the difference between the true odds of an event happening and the odds that the casino will pay out if it does happen. The higher the house edge, the worse the odds are for the player. In other words, it’s the “price” the casino charges for you to place a bet.

To calculate the house edge on a particular bet, you subtract the probability of winning from 100%. For example, if a bet has a 50% chance of winning, its house edge is 50%. That means that for every $1 you bet, you can expect to lose 50 cents on average over the long run. There are many bets on online gambling platforms where the house edge is less than 1%, and some even have 0%. But there are also plenty of bets that are 5% or more.

Return to player

Return to player (RTP) measures how much a game pays over time. It is the percentage of the total amount wagered on the game. For example, if a game has an RTP of 95%, that means that for every $100 wagered, the game will pay out $95 on average.

The difference between RTP and house edge is that the former is a theoretical number based on the long-term average payout of a game. At the same time, the latter is the actual percentage the casino will keep as profit from each bet. Therefore, games with higher RTPs are more favorable to players, while games with higher house edges are more favorable to casinos.

Random Number Generator


Random Number Generator (often abbreviated and mostly referred to as RNG) is a piece of software used to give random numbers that determine the results of games. Without an RNG, casinos could rig the games in their favor, making it impossible for players to win. That’s why please always ensure that any online platform you play at uses a certified RNG.

Thankfully, most reputable casinos, such as the mentioned N1 Casino Greece and others, display their RNG certification prominently on their website. So, if you’re unsure, look around the platform’s homepage — if they’re using an RNG, they’ll be sure to let you know!

Provably Fair algorithm

Just as in RNG, the provably fair algorithm is used to verify that each game round is fair. This algorithm is based on blockchain technology, allowing players to see that the casino has not tampered with the game results. Provably fair games are mainly found in crypto gambling platforms.

Players need to know the seed number and the hash algorithm to use the algorithm. The former is a random number generated before each game round. The latter is a mathematical function that takes the seed number and produces a new, unique number. By knowing the two, players can verify the fairness of each bet.

What are the benefits of playing at an online casino?


For starters, online casinos are much more convenient – you can play from the comfort of your own home, or on the go with mobile casino apps.

What’s more, online casinos offer a wider range of games than most land-based casinos. You’ll find everything from classic slots and table games to live dealer games and progressive jackpots. And with so many different software providers creating new games all the time, the choice is always fresh and exciting.

Another big advantage of online casinos is the bonuses and promotions they offer. Land-based casinos rarely give out bonuses or run promotions, but online casinos will often give you extra cash to play with or free spins on popular slots. This gives you a great opportunity to boost your bankroll and try out new games.

How to choose an online casino

There are so many casinos to choose from and it can be difficult to know which one is right for you. Here are some key concepts to keep in mind when choosing an online casino:


Make sure to do your research and only play at casinos with a good reputation. There are many review sites where you can read about other players’ experiences.

Banking options:


Choose a casino that offers banking options that are convenient for you. Some casinos only accept certain types of payment, so make sure to check before you sign up.

Bonuses and promotions:

Many casinos offer Welcome Bonuses and other promotions to attract new players. These can be a great way to boost your bankroll, but make sure to read the terms and conditions first to avoid any surprises.

Customer support: In case you run into any problems while playing at the casino, it’s important to have good customer support to help you resolve them. Check out the casino’s customer support options before you sign up.

With these concepts in mind, you should be well on your way to finding the right online casino for you.
