One of the most important tips you could consider when playing roulette as a casino newbie is sticking to the table minimum and focusing on only playing the outside bets. Bet on either black or red for every new spin and you will enjoy a 1:1 payout while covering 18/38 potential combos.
There is no such think as a 100% roulette strategy. It's only an illusion. People think because they can cover 80 - 90% of the board and show small profit compared to amount they wager that they figured out a system. But guess what even know your odds are greater to win at beginning of every spin.
