Almost every casino myth makes the same hidden assumption: that the game remembers what happened before, or that someone adjusts it while you play. Certified random number generators do neither. Each spin, roll or deal is drawn independently of the previous one, and that single fact disposes of most of the folklore below. Where a myth contains a grain of something real, this page says so.
Myth 1: Machines Run Hot and Cold
A slot that has just paid out is not "cooling down", and one that has not paid for an hour is not "warming up". The result of each spin is drawn by the generator at the moment you press the button, with the same probabilities every time.
What people experience as streaks is variance. The return to player (RTP) of a slot — say 96% — is an average over millions of spins. Over a session of a few hundred spins, the actual return can sit far above or far below that figure, and clusters of wins and losses appear naturally in any random sequence. A streak describes the past; it says nothing about the next spin.
Myth 2: A Number Is Due
On a European roulette wheel there are 37 pockets, 18 of them red. The chance of red on any spin is 18/37, or 48.6% — after one black, after ten blacks, after a hundred. The wheel does not keep score.
The best-known illustration is the run at the Monte Carlo Casino in August 1913, when black reportedly came up 26 times in a row and players lost heavily betting that red was "due". The belief now carries the name of that night: the Monte Carlo fallacy, or gambler's fallacy.
Myth 3: The Casino Tightens a Slot When You Win
An online casino cannot quietly lower the payout of a game in the middle of your session; the generator and the paytable are fixed in the certified game build. But there is a real fact behind this myth that is worth knowing: many game providers release the same slot in several RTP versions — for example 96%, 94% and 92% — and the operator chooses which version to offer.
So the same title can return less at one casino than at another, permanently rather than in response to your wins. The practical defence is to open the game's information or help screen, where the RTP of the version in front of you is normally stated, and compare it with the figure the provider publishes.
Myth 4: A Betting System Can Beat the Edge
The Martingale — double your stake after every loss, return to the base stake after a win — feels unbeatable because it usually ends a sequence one unit up. The arithmetic shows where the cost hides.
Worked example (assumed numbers). European roulette, betting red, base stake 1, table limit allowing seven bets in a sequence (1, 2, 4, 8, 16, 32, 64). The chance of losing all seven is (19/37)7 ≈ 0.94%. So 99.06% of sequences win 1 unit and 0.94% lose 127 units. Expected result per sequence: 0.9906 × 1 − 0.0094 × 127 ≈ −0.21 units — exactly the 2.7% house edge applied to everything staked along the way.
No staking pattern changes the edge on any single bet, so no combination of bets can turn a negative expectation positive. Systems change the shape of the results — many small wins, occasional large losses — not the average.
There is also a practical catch at Diesbet specifically: its general rules (checked 4 October 2026) say that accounts using the Martingale or similar systems systematically can be closed and the winnings not paid.
Myth 5: Lucky Seats, Lucky Times, Lucky Charms
The time of day, the phase of the moon, the seat you choose, the dealer on shift and the charm in your pocket have no route into a generator's output. In live dealer games the outcome comes from a physical shuffle or wheel, and a change of dealer does not change the probability of any result. These beliefs are harmless in themselves; they become expensive when they justify a bigger bet.
Myth 6: A Near Miss Means You Were Close
Two jackpot symbols and a third just above the payline look like "almost" winning. In outcome terms a near miss is simply a loss. Research on gambling behaviour has repeatedly found that near misses nevertheless increase the urge to keep playing — Clark and colleagues reported in the journal Neuron in 2009 that they activate reward-related brain circuitry much as wins do. The feeling is real; the closeness is not.
| Myth | What it assumes | What is actually true |
|---|---|---|
| Hot and cold machines | The game remembers recent results | Each spin is independent; streaks are variance |
| A number is due | Outcomes balance out in the short run | Red on European roulette is 48.6% every spin |
| Casino tightens a winning slot | Payouts change in real time | No — but RTP versions differ between casinos |
| Betting systems | Stake patterns change the edge | Martingale on red: about −0.21 units per sequence |
| Lucky seats, times, charms | Outside factors reach the result | Nothing reaches a certified generator |
| Near misses | You were close to winning | A near miss is a loss that feels like progress |
Every myth on this page claims the game remembers something. Certified generators hold no record of previous rounds, which is the single fact that disposes of hot machines, due numbers and lucky seats all at once.
What Is Not a Myth
Two things that sound like myths are true. The house edge is real and built into every paytable: it is the reason the casino can exist, not evidence of rigging. And volatility is real: two slots with the same RTP can behave very differently, one paying small amounts often, the other paying rarely but in larger amounts. Neither fact helps predict the next result; both help you choose what to play and how much to stake.

Questions About Casino Myths
Are hot and cold slot machines real?
No. Each spin is drawn independently by the random number generator, so a machine that has just paid out is no less likely to pay again. Streaks are what variance looks like over a short session; they carry no information about the next spin.
Can an online casino change a slot's RTP while I play?
Not during a session, because the certified game build fixes the generator and paytable. However, many providers offer the same slot in several RTP versions, such as 96%, 94% and 92%, and the operator picks one. Check the game's information screen for the RTP of the version you are playing.
Does the Martingale system work?
It wins small amounts often and loses large amounts occasionally. On European roulette with seven doublings from a stake of 1, the expected result is about −0.21 units per sequence, which is the 2.7% house edge applied to everything staked. No staking pattern changes the edge.
Is the gambler's fallacy the same as the Monte Carlo fallacy?
Yes. Both names describe the belief that an outcome becomes more likely because it has not happened for a while. The second name refers to the 1913 run at the Monte Carlo Casino, when black reportedly came up 26 times in a row.
