Roulette Bias:

Roulette bias is a term used to describe a roulette wheel that un-fairly favors a particular sector, this occors naturally on all roulette wheels over time, but can only be found at roulette tables in "land based" casinos and not online roulette.

Roulette bias in simple terms:

Simply speaking imagine this example, you have your own roulette wheel in your house and it's sitting on your dining room table, the only problem is that the table has a slightly wonky leg and the wheel is tilted. Everytime you spin the wheel it is more likley to land in one particular sector and this is what roulette bias is.

Of course, in a real casino there are no wonky legs, everything is measured to be exactly flat and then audited on a regular basis by an independant party.

Roulette bias in the real world will occor for other reasons, such as; "wear and tear" the wheel does thousands of spins a day at some casinos and eventually it all takes it's toll, or maybe the table is located near the entrance and there is a very slight gust of wind everytime someone walks in. Whatever the reason is, it does happen and it's your job to learn how to spot a bias roulette wheel.

How to find a bias roulette wheel:

Roulette bias at a reputable casino would be so minute that you would need to record thousands of spins and then analyze them all, so you need an easy way to record the spins and then analyze at your lesure.

Many offline casinos now keep a database of their spins and release them to the general public via their website, so this was the hard part out of the way, now you just have to download the spin data and find a way to analyze them.

How to analyze roulette spin data and find roulette bias:

Remember what you're trying to do here, you're finding a wheel that un-fairly favors a particual sector, so the first step is to split the wheel into equal sectors. Once you've done this you can start a new excel spreadsheet, import the spin data and setup some filters.

The maths: you need to work out the percentage of times each sector has shown, and then compare it with the others.

The take a trip to the casino and just hope they didn't fix the wheel already.
