This game is often played when you’re running out of cash in a casino because you can bet as low as RM1 per game. It would not be a game that people will bet all their money on because the edge is very high. So if you want to chill a little, Keno is the best choice. If you're playing online the odds are often much better. Of course, the pace is much faster, so you could still wind up losing more money by playing online even though the odds are better because you're placing so many more bets.
Many gamblers will never recommend people to play Keno. In The New Gambler's Bible, Arthur Reber says, "I wouldn't play it with Monopoly money, and I hope you never will." Now, I think Reber's a great writer, and his Bible is a fantastic book, but I have to disagree with him on this.
Really, is it so bad to blow a little money on a Keno ticket for a chance to win a quarter million ringgit/dollar? So what if you've lost a whole ringgit/dollar? We all know that gambling is usually a losing proposition, so what's the crime if you limit your Keno play to what you can afford to lose and you fully understand that the odds are bad? Sure the house edge is high, but playing a few cheap games is certainly not going to devastate you. You don't have to get a fantastic expected return on every ringgit/dollar you spend — for example, what's the expected return when you pay to see a movie? You "lose" 100% of your money with no chance of getting it back. But you got some entertainment value out of it, so why is the entertainment value of buying a keno ticket any less valid?
