Hi heatmap, a few members (including myself, Reyth, and Jesper) have written trackers and applications, unfortunately the links are scattered around in various threads. Perhaps we should have a dedicated section for this; what do you think, Kav?
I can add a couple of links to Reyths':http://betsoftware.cc/
The designer of the excel bot, Nick, sometimes posts here. He may be able to give you more info.http://www.rouletteresearch.com/
A lot of excellent and professional sofware here, for both APs and system players, but not free.
Your username reminds me of an app I wrote years ago when I was active on another forum. It's a kind of "heatmap" of the roulette layout. It's a bit clunky, but functional.
[edit: I see Kav has removed the link to the forum. Fair enough!
. So I've copied the instructions]:
This is a "tracker" program I wrote a few months ago. It gives a visual indication of the "state" of any number, split, street, corner... in terms of the number of standard deviations from the mean over a sequence of spins.
Just click on the numbers as they come in and click "reset" to start over. The program updates the standard deviation of each location and colours it accordingly.
You can select how many spins over which you want to see the measure by moving your mouse cursor over one of the number squares at the bottom of the window (25 - 100). Note that "N" means the total number of spins.
Yellows and Reds denote "warm" and "hot" locations respectively, green and blue are "cool" and "cold". These are defined as follows:
Yellow = more than 2.0 SD but less than 3.0
Red = equal to or more than 3.0 SD
Green = less than -2 SD but more than -3.0 SD
Blue = equal to or less than -3.0 SD
So in the attached image, over the last 25 spins (because the cursor is over 25), Red is cool, black is warm, column 3 is cool, the corner 16-20 is warm, as is street 10-12, number 10, corner 10-14, split 10-13 and split 17-20, while split 10-12 is hot.
The program also tracks repeaters over the last 10 spins (top left field), and any number repeating is shown (number 11 has repeated in the example). This works on a rolling basis. You also get "pop-ups" when any dozen or column "sleeps" for 15 spins or any 6 line sleeps for 40 spins.
Note that the layout doesn't include zero because I use this on Betvoyager no-zero wheel. I'm not recommending any strategies or systems in particular, but you can learn a lot about random by using this program.
Then there are some commercial programs like "roulette sniper", "roulette key gold", etc.
