Can winnings be predicted based on past rotations

1) Main fact: each spin is independent

In licensed online slots, the result is determined by the server random number generator (RNG), which produces a new random number every time the spin is pressed.

Winning or losing on previous backs does not affect the chance on the next.
The game has no "memory" - it does not "remember" how long ago there was a bonus or a major skid.

2) How RNG works in practice

1. When you click (or auto-back), the server RNG generates a number.
2. This number is mapped to a particular combination of symbols on the reels.
3. The result is fixed even before the rotation animation.
4. All events are independent: even two identical consecutive skids are pure probability, not a "series of returns."

3) Why past backs don't give a prediction

Gambler's fallacy - player error: "since there was no bonus for a long time, then it will be soon." The probability of a bonus is the same every time and does not "accumulate."
No cycles: license slots have no programmed drain/recoil phases - there is only a statistical distribution by RTP and variance.
Dispersion creates the illusion of patterns: after a long minus, a skid may occur, but this is not a consequence of "accumulation," but an accident.

4) Why some slots feel like you can "guess"

Persistent states: In individual games, symbols/coins/scales accumulate on the screen. When they are nearly full, the probability of a bonus is higher, but this is a feature of mechanics, not "reading history."
Must-hit-by jackpots: if the jackpot "should fall to $ X," then when approaching this value, the chance actually increases - but this is a rare special case and it is not associated with ordinary spins.

5) What can and should be kept in statistics (but not for forecasts)

Hit rate - the frequency of any winnings.
Bonus frequency (average interval in backs).
Average winnings (in bet ×).
MDD - maximum balance drawdown per session.
This data is needed to:

• Understand your own distance of "patience" to the bonus.
• Set up stop loss and time limits.
• Exclude slots in which the actual RTP is noticeably lower than the declared one.

6) Why spin stories are often cheated

Random clusters: in short sessions, events "thicken" or, conversely, go into long empty series - this is a statistical norm.
Selection by results: the player remembers that "after a series of empty slots he gave," but forgets dozens of cases when the bonus never came.
Myth generation: rumors about the "slot mood" often come from unlicensed sites where mathematics may be under the control of the casino - in such cases, honesty is no longer there.

7) Finger math

If the bonus chance is conditionally 1 time in 200 spins, then:

• The probability of getting a bonus on the next back ≈ always 0.5%, even if there were no 500 backs in a row.
• The lack of a bonus in the previous 200, 300 or 500 backs does not increase this chance in the license slot.

8) How to use history correctly

To set personal limits: "I go out if there is no bonus for 2 × of my average distance."
To estimate volatility: the length of the empty series and the amplitude of payments.
For self-control: identifying where you break stop rules more often.

9) Common Sense Checklist

I only play in licensed slots (RNG certified).
I do not bet "on a whim" because of a long series of empty ones.
I use history only to analyze myself, and not to "guess."
I fix the limits before the start, not in the process.

Result

In license slots, it is impossible to predict the gain from past rotations: each rotation is an independent event determined by the RNG. History is needed for discipline and planning, but not for "guessing" the outcome. An attempt to build a strategy on "series" is a direct road to tilt and violation of bankroll management.
