Slot patterns (pola slot): does any of them actually work?
None works. We tested the four most popular patterns on 3,895,678 lab spins: after a big win, after free spins, after heavy losses, and after a run of empty spins. In every case, the next 100 spins paid the same as usual, within chance.

What is a slot pattern?
A "slot pattern" (pola slot) is a way of playing believed to make a game pay more often: switch games after a big win, stop after free spins, keep going after losses because "it will pay back soon", or wait after a run of empty spins. There are also manual-auto-turbo patterns and up-and-down betting patterns.
All of them rest on one assumption: that what just happened in a game affects what happens next. That assumption can be tested.
How do we test a pattern?
We turn each pattern into one question: after event X, do the next 100 spins pay more or less than usual? We use 3,895,678 lab spins recorded in order, game by game.
"Usual" means that game's own average, so wilder games do not muddy the result. Each event is counted once, and the 100 spins after it are not reused for the next event of the same kind, so the range of chance is calculated honestly.
The result: does any pattern change anything?

Of 8 results, 1 stray slightly outside their range (After free spins (win frequency)). With a 95% range, about one in twenty results will by chance, and the difference here is tiny: no pattern changes the outcome by anything a player could feel.
Pattern 1: "After a big win the game goes cold"
This pattern says: after a game gives a big win it goes "cold", so you should move to another game.
We saw 3,482 wins of ×100 or more. Over the next 100 spins the payout was −1.5% against normal (range of chance ±4.3%) and win frequency −0.2%. The game does not go cold. Switching games is fine, but not because the last one is "used up".

Pattern 2: "After free spins the game rests"
This pattern says: after free spins land, the game "rests" for a while, so stop for now.
After 10,287 free-spin rounds, the next 100 spins paid +0.6% against normal (±2.1%), win frequency −0.3%. There is no rest.
Pattern 3: "After heavy losses the game pays you back"
This pattern says: if you have lost a lot on a game, it "owes" you and will pay back soon. It is the most expensive pattern, because it keeps people playing while they are losing.
We found 1,465 times a game returned under 30% over 200 spins in a row. The next 100 spins paid −0.5% against normal (±7.2%), win frequency +0.4%. The game pays nothing back. Losses already made stay made, and the next spin starts from zero.
Pattern 4: "A run of empty spins means it's about to pay"
This pattern says: after many empty spins, a win or a scatter is "close".
We found 3,025 times a game paid nothing for 20 spins in a row. The next 100 spins paid −0.2% against normal (±3.4%), win frequency +0.5%. Empty spins do not "charge up" anything. The same holds for free spins: the chart below uses continuously updated lab data.

What about manual, turbo and up-and-down betting patterns?
Manual-auto-turbo patterns and up-and-down betting patterns we cannot test: our lab spins each game one way at one stake. So we will not claim a result for them.
What we can say: those patterns rest on the same assumption as the four above, that a game "remembers" something. Four times we tested that assumption with data, and four times the answer was the same: nothing is remembered. The same goes for time of day: we tested all 24 hours, and there is no hot hour.
How can I check this myself?
- Download our daily spin archive. Each row is one spin, in order, with its win. Verify the data →
- Pick a pattern, find every occurrence, and average the 100 spins after it. Compare with that game's average.
- Read how we record and reconcile every spin. Full methodology →
Frequently asked questions
Do slot patterns really exist?
The patterns we tested do not work. After a big win, after free spins, after heavy losses and after empty spins, the next spins pay the same as usual.
Should I switch games after a big win?
Not for that reason. Our data shows a game does not go cold after a big win.
Will the game pay back my losses?
No. After 200 heavily losing spins, the next spins pay as usual. Playing on to "win it back" is the fastest way to lose more.
Does a run of empty spins mean a scatter is close?
No. After 20 empty spins the chances are the same as usual. Free spins do not get more likely after a long wait either.
What about manual, auto and turbo patterns?
Our lab cannot test those. But they rest on the same assumption, that the game remembers something, and that assumption failed every test we ran.
Why do patterns feel like they work?
Because people remember when a pattern "worked" and forget when it failed. With enough players, every pattern works for someone by chance.
