Here are some suggestions for filtering your numbers. I play Ontario Keno 20/70 -- I have done ok, last year $16,000 gross.
1-Do spreadsheet with overdue numbers,
(numbers not played the last 6 days +)
For each number (+1) and (-1) then (+2) and (-2)
Do this for some of your old draws, compare with
results, I think you will find 12 correct numbers on average in the -1 and +1 columns
2-Do above with numbers played last night..with some luck you will find 10-12 numbers on average also.
3- Get a Keno card for your lottery, mark
numbers from 1 & 2 above ( overdue and last night's)
create combos with the UNMARKED numbers.
Please do the above and let me know what you find out. Good luck
Btw..These tricks work with others lotteries too...now if only I could find a good software designer
to write a program for above...and yes you can win at Keno, but you have to work at it.
Finally, where are your mirror pairs in relation to:
-overdue numbers
- last night's draw ?
This is an IMPORTANT clue ! Use some of above ideas and you should be able to get 4/4 before the end of next week,
I have up to 7 lines hitting 4/4 some draws.
