After playing slots for many years I 100% believe there is no way they are random!
Hey, I've come back a bit on another thread so now I'm hooked on CM again - so I'll chime in, if I may
Here's a simple explanation - you and I will toss a coin. You toss it, your coin. Let's assume that over many many tosses, you'll hit heads about half the time and tails, half the time.
Odds are 50% for tails and 50% for heads. Now, every time you toss, I'll pay you a dollar, for a chance to win my bet back + 90c. I choose heads. Every time you toss and heads do not happen; you will take my dollar.
Let's say you spin this 200,000 times.
100,000 times it comes heads.
100,000 times it comes tails.
Every time it came heads, I took 90c from you + my original bet of 1$ that is returned to me. Every heads outcome, you will take 1 and give me back 1.90.
Every time it came tails, you took 1 dollar from me. I would lose my 1 dollar.
Even though during our 200,000 random bets, there were times where it came heads 20, even 50 times in a row and I was up & winning, there were also times where it came 20, 50 and even 100 times in a row for tails and you were winning. Each outcome was randomly tails or randomly heads. However, in the end - both tails and heads came out an equal number of times. This happened randomly, with each toss.
However, after 200,000 tosses, you took 100,000 dollars from me for every "tails" outcome that I lost. And I in turn, took 90,000 dollars from you for every heads outcome that I won.
In the end, you accepted 200,000 dollars, 1 for each bet, and paid back out 190,000 dollars (100,000 in my winnings bets back + 90,000 in my 90c per bet winnings) for the winnings bets.
For my 200,000 dollars of bets, I returned 190,000 dollars back, losing 10,000. I returned 95% of total bets. "Return to player" aka RTP was 95%
You profited 10,000 dollars from total bets I made. You profited 5% of total bets. Aka, you had 5% house edge
That's how it works. Casinos always pay out slightly lower odds, than the odds of the winning hand happening.
You can take above example on a dice and say that you pay 5 to 1 for every "6" that comes up.
In conclusion: Random works. There is no need to not make it random
