You may want to keep your bets together in order to make sure that you are not betting against yourself For example if you have a bet on 18, then don’t bet on an odd number that belongs to a black block, because 18 is a red and even number. If at all you are interested in placing secondary bets than make them in correspondence with your first bet. This is a much safer way to play roulette, that doesn’t invite taking a lot of risks. In terms of risk taking it is also very important to keep a check on the way you gamble and the right way to do it. The atmosphere of the entire casino as well as being on a winning streak can make you want to continuously keep on going higher on bets, but you have to realize the right time to stop, as many big prize winners have lost their entire winning amount by giving into their greed to play more with the hope of winning more.
