Or if you decide to become a gambler, I recommend learning Black Jack, as the odds of winning per attempt is 40%, and if you get yourself educated in basic strategy of Black Jack, the odds becomes 47%, and plus if you learn how to do Card Counting (in your head, which is not illegal, as nobody can know what you are counting in your head), the odds go beyond 51%, and you beat the house... but that requires disciplined training of your mind, and you got to see how many decks the Black Jack table is using... normally should be 6 decks... but I will not be surprised in Singapore they use 8 decks because of the super kiasu culture.
My proposal to all readers, DO NOT GAMBLE.
If you want to learn the various strategies used in "Card Counting" read Ken Ustons book "Million Dollar Black Jack". He was part of a card counting gang that made $$$ from the casinos by counting cards

Think of it as the 10 year series of card counting
