This is one of my winning methods, it consists of certain criteria in order to pick winning numbers.
Bets flat on 3 numbers, these 3 numbers are changing from time to time.
Write down every number as it hits, wait for 3 repeaters and bet them till one of them hits for third time.
While you are betting those 3 numbers another repeat could happen, in this case remove the older repeater from your bet selection and replace it with the new one.
Every time you are betting no more nor less than 3 numbers with flat stakes, when one of these hits stop and wait for 3 new repeaters.
If you don't win within 12 consecutive bets/spins stop and wait for 3 new repeaters.
On average you find 3 repeaters within 18 spins, if there are less than 3 within 18 spins window do not bet, there must be 2 within 12 or 3 within 18 spins.
If you have an opportunity of 2 within 12 spins then start betting these 2 and if a third repeater while you are betting two add this third to your bet selection.
2 repeaters for 18 spins or 3 for 12, not more than 3.
The 12/18 spins window opportunity should be updated on a rolling basis, after every new outcome delete the oldest result in order to keep a record of the most recent 18 spins.
It doesn't matter if more than 3 repeaters occur within those spins, just make sure you are betting the 3 newest.
Profit grow fast even with flat bets!:-)
