Flat betting the board is a terrible strategy, try 9 streets .20 on each street 250 bankroll and martingale losses. This gives you 7 losses in a row and 2/3 your bankroll back in 1 win. You can play all day like this and save your bankroll so you can get in the fire blaze rounds more often. That is where your profit comes from. If you want higer bets do the math for the bankroll.
