Using roulette bet.
bet only side bet x5 double rows if you place 5 dollars on 3x different double rows if you hit your winnings is 25$ with a 5 dollar bet. so $15 bet winning if hit is 25$
challenge is to always hit and if you missed you x2 bet if you lose and if you won you go back to $5 bet. with a bank roll of 1000$ you can even stack the 3 rows on top of eachother which will make the connecting numbers would win $50 instead of 25. try it would using strategy of high or low. your bound to hit either or .
