Roulette Power Play

Bet 3 units on Low and the last 2 unrepeated lines which are on the High section with 1 unit each.
If you lose switch to 3 units on High and the last 2 unrepeated lines which are on the Low section with 1 unit each.
When you win double each section proportionally, the goal is to to do this (doubling) 3 times in a row, thus you are looking for a 3 winning streak.
After achieving this color up your chips and move to another table or call it a day.
Never raise when you lose but switch to the opposing section of the table.
Regarding your unit value (1,5,10,25,50,100...etc) you may find this kind of betting very rewarding.
One last thing, if you lose 3 times before you could win 3 times in a row move from the particular table or quit for the day.
