The $20 roulette strategy, otherwise known as the Martingale Strategy is an almost guaranteed way to make sure you win at the casino with $20. It works like this: Step One: Bet $20 on red, and if the ball lands on red you've won. You then proceed to take your money and stop playing, you've beaten the online casino.

A 20X wagering requirement means you must wager the amount of your bonus 20X over in order for you to collect the bonus and subsequent winnings.
