For Australian lotto games I have prepared a Powerpoint Presentation which gives yourself some useful information on the subjects of Lotto Statistics including Ratio of Odds & Evens
numbers drawn, how numbers are selected and can be presented for Saturday, Ozlotto, Monday or Wednesday Lotto games.
More Java programs are currently being written to assist you in selecting your numbers. Frequency listings can be used however the use of these is very inconsistent, you might be fortunate.
A certain number of weeks over a 100 week analysis contain at least 2 consecutive numbers.
Numbers that have HISTORICALLY appeared together a lot of times can also be utilised however same as frequency charts these are also inconsistent and not relied on.
To view all of my interactive computer program outputs your computer has to be Java Enabled, as all of the programs are written in Java.
The formula used in selecting all of the numbers for any Lotto game is exactly the same.
