How the casino earns and from what RTP is formed

To understand the mechanics of online casinos, it is important to know that they exist not only due to player losses, but due to the built-in mathematical advantage - house edge. This percentage is included in every game and ensures that the casino makes a profit over the long distance.

1. Casino's main source of income is a mathematical advantage

House edge (casino advantage) is the percentage of winnings that remains for the operator. For example, with a 5% advantage with each bet of $100, the casino mathematically "earns" $5.
In slots, this advantage is expressed through RTP (Return to Player) - the theoretical percentage of return to the player. If RTP is 96%, then at a distance, players will receive back $96 out of every $100 bets, and $4 will remain a casino.
In board games like roulette or blackjack, house edge depends on rules and bets.

2. What is RTP and how it is formed

RTP is a statistic calculated on millions or billions of spins.
Formed by the game developer based on a mathematical model and a random number generator (RNG).
RTP does not change in real time for an individual player, but reflects the long-term picture for all participants.
Volatility affects the distribution of winnings: at high RTP, a game can be both low-volatility (frequent small winnings) and high-volatility (rare but large winnings).

3. Casino revenue by game type

Slots - fixed RTP and house edge, profits are stable with a large number of bets.
Roulette - the advantage depends on the option (European roulette ~ 2.7%, American ~ 5.26%).
Blackjack - With the right strategy, the house edge player can drop to 0.5%, but on average higher.
Live games - income is formed according to the same principles, but taking into account the bets of a large number of players at the same time.

4. Role of Providers and Casinos in RTP

RTP is set by the developer, not the casino itself.
Licensed providers are certified by independent laboratories (eCOGRA, iTech Labs).
The casino cannot "tweak" RTP in a licensed game, but can choose versions with different levels of return (for example, 94% or 96%).

5. Casino earnings myths

Myth: the casino "manually" manages the results - in licensed establishments this is impossible.
Myth: RTP is a guarantee of winning a short session. In practice, short-term outcomes can vary widely.
Myth: if the slot did not give for a long time, he is "obliged" to give out a large win - the random number generator does not take into account the history of bets.

6. Conclusions for the player

The casino earns steadily at the expense of house edge, and RTP shows how much is returned to players in the long term.
To increase the chances of winning, it is better to choose games with high RTP and optimal volatility.
Understanding these metrics helps you play mindfully and avoid false expectations.
