Don't put all your money on 1 number
Many people have this feeling that it's their day or they have a lucky moment and think today is the day to visit a casino. Even worse some people feel so lucky that they think they can put all their money on 1 number in the roulette game and will win a huge amount.
Also you can find videos on YouTube from people putting all the money on 1 number and win millions but look out with this. You don't know how much money already lost before by that player and can you trust a video on Youtube so much to do the same with your money?
It's better to increase your chances of winning by choosing more numbers although you will win less money in one winning spin. You can play more games and enjoy more from the Roulette game. Unless you don't care or have enough money that you really want to try this strategy. It's all up to you.
Look at other players when playing in a land based casino
Of course you can go to a casino and immediately place your bets on the roulette table. But patience is the magic word when visiting a land based casino. The second word to remember with roulette is observation. There are many experienced roulette players at your table who are not more lucky than you but they have some tricks and experience where you can learn from. They might know the way of spinning off the dealer or when it's the right time to place a bet. Observe first how these experienced players are playing and try some moves yourself to find out what works best for you.
These are just two simple tips that will not guarantee any winning spins but might help you a bit the get started.
