Colour Prediction Tricks and Formulas Tested
Four popular rules were run against 100,000 simulated fair rounds, and every one landed very close to 50%. Here is the table, why tricks seem to work for a while, and a way to test any trick yourself.
The tricks people share
Five ideas keep turning up in videos and chats. The table shows what each tells you to do and which tested rule covers it.
| Trick | What it tells you to do | Covered by |
|---|---|---|
| Follow the last colour | Bet that the next result matches the last one | Rule 1 |
| Switch every time | Bet that the next result differs from the last one | Rule 2 |
| Switch after two or three of the same | Wait for a run, then bet that it ends | Rule 2, but only after a run |
| Follow the majority of the last five | Bet on the side that came up most in the last five | Rule 3, and its mirror Rule 4 |
| Read the trend chart | Look for patterns in a grid of past results | Any pattern you spot becomes a rule like these |
What 100,000 rounds say
Inputs: 100,000 simulated rounds, each a fair 50-50 result with no memory. A rule saw only the rounds before the one it was guessing, so 99,995 rounds were tested per rule. The seed, a starting number for the random rounds, is fixed, so anyone can repeat the run.
| Rule | In plain words | Right |
|---|---|---|
| 1 | Repeat the last result | 49.95% |
| 2 | Do the opposite of the last result | 50.05% |
| 3 | Follow the majority of the last five | 50.26% |
| 4 | Go against the majority of the last five | 49.74% |
Every rule lands within 0.26 of a point of 50%. Rules 1 and 2 are exact opposites, as are Rules 3 and 4, so each pair adds up to 100%. Switching sides, or waiting for a run first, only changes which rounds you are right in, not how many on average. The pattern systems page shows the same test in the simulator, on one fixed run, so you can check these numbers yourself.
Two ideas that feel like knowledge
The gambler’s fallacy is the feeling that a long run makes the other result “due”. After five reds in a row, green seems overdue. But a round has no memory of the one before it. The next one starts fresh, with the same chances as the first round of the day.
The hot hand is the opposite feeling: a run means the streak is “on”, so ride it. It fails for the same reason. When rounds have no memory, a run says nothing about the next one. Both ideas treat the past as a cause when it is only a record. The streaks guide shows how long runs get when nothing special is going on.
We cannot see inside any platform, so this describes what chance does, not what one game does. If someone says a game holds a pattern, the test below checks the claim.
Why a trick seems to work for a while
Short stretches are noisy. In 20 two-way guesses, blind guessing averages 10 right, give or take 2.2. So 12 right is unremarkable, and 14 or more right turns up 5.77% of the time (20 rounds, each right with chance 0.5). A night when a trick works is remembered, the nights it fails are not, and among many people trying many tricks, the lucky ones are the ones who post.
How to test any trick yourself
- Write the rule in one sentence that leaves no room for judgement, such as “bet the same side as the last round”. A rule you adjust after seeing results is a rule fitted to noise.
- Collect about a thousand rounds of real results, in order. If your game shows a results history, copy from it; we could not see this platform’s game pages, so check yours.
- Apply the rule to each round using only the rounds before it, and count how many it gets right. A spreadsheet can do this for you.
- Compare your count with luck. Over 1,000 rounds, blind guessing averages 500 right, give or take 15.8, and the table below shows how rare a modest edge is.
- Try the rule again on a fresh set of results that it has not seen.
Why about a thousand? The same hit rate means very different things at different sizes.
| Rounds written down | A 55% hit rate is | Blind guessing reaches it or better |
|---|---|---|
| 20 | 11 right | 41.19% of the time |
| 100 | 55 right | 18.41% of the time |
| 1,000 | 550 right | 0.09% of the time |
Inputs: each guess right with chance 0.5 under luck alone. At 100 rounds, blind guessing averages 50 right, give or take 5.
With a hundred rounds, a rule that is right 55 times looks just like luck. With a thousand, 550 right is rare enough to take seriously, while 520 right still turns up 10.87% of the time by luck alone. A short test can only expose a huge edge; a small one, a few points above half, hides in the luck until about a thousand rounds.
What the simulator on this site does
The simulator’s systems table runs these rules on 100,000 fair rounds with a fixed seed, so you see the same numbers every time. Its streaks part draws fresh random rounds whenever you press the button. Both show what chance looks like, the yardstick every trick and predictor has to beat, and neither says anything about a particular platform. The predictor apps page uses the same yardstick on a different claim, and the overview of hacks and predictors puts the rest in one place.
Common questions
Does switching colour after three of the same in a row work?
It changes which rounds you are right in, not how often. When each round starts fresh, all four rules we tested landed near 50%, for example 50.05% for always doing the opposite of the last result over 99,995 simulated rounds.
What does the trend chart on a colour game tell me?
It records past results in a grid or a line. We could not see this platform’s game pages, so check yours. If rounds start fresh each time, the chart cannot say what comes next, and the patterns you see in it are what chance looks like.
How many rounds do I need to test a betting pattern?
About a thousand. A 55% hit rate is reached by blind guessing 18.41% of the time over 100 rounds (55 or more right), but only 0.09% of the time over 1,000 rounds (550 or more right), with each guess right with chance 0.5.
Why did a pattern work for me last night?
Short stretches are noisy. In 20 two-way guesses, blind guessing gets 12 or more right 25.17% of the time (each guess right with chance 0.5), and a good night is remembered more than a bad one. Test the pattern on far more rounds before you trust it.
