Every single game on a casino floor is meticulously designed with a built-in mathematical advantage for the operator.
Understanding this concept is the most important lesson any gambler can ever learn before placing a bet.
The edge is essentially the difference between the true odds of an event happening and the actual payout you receive.
Take European Roulette: there are 37 numbers on the wheel, meaning your true odds of hitting a single number are 1 in 37.
When discussing slot machines, the house edge is usually referred to by its inverse metric: Return to Player (RTP).
An RTP of 95% indicates that the machine is programmed to pay back $95 for every $100 wagered over its lifetime.
While you can absolutely win in the short term due to variance, the math is inescapable over the long run.
