Betting is not universally recognised as prohibited in Christianity. But in that respect it’s like drinking alcohol. Ok in moderation and if you are in control of it. But if it starts to take control of you, that is bad.

In general, and not just as part of Christianity, if you feel like betting you should set yourself a budget, or a limit, that you are prepared to lose in the name of having a good time. Like going to a concert, or the cinema, you can spend a bit of money to have a good time without any problem. The problem comes when you can’t limit yourself to that budget.

Christianity in general is not a rules based controlling religion. Christ was pretty much against the idea of living according to rigid rules. He was much more about compassion, love and forgiveness.

Many Christians wonder if gambling is a sin and what the Bible has to say about it. While casinos, lotteries, and other of today's get rich quick games aren't specifically mentioned within the Bible, God has still warned against the temptation. Most often when people gamble it is because they become addicted to the love of money. A simple game can become a sin when it takes over our minds and hearts and leads us down a road of never being satisfied. Study the following Bible verses about gambling and see why God encourages us to stay away from it.

1 Timothy 6:10

For the love of money is a root of all kinds of evil. Some people, eager for money, have wandered from the faith and pierced themselves with many griefs.

Deuteronomy 8:18

But remember the LORD your God, for it is he who gives you the ability to produce wealth, and so confirms his covenant, which he swore to your ancestors, as it is today.

Ecclesiastes 5:10

Whoever loves money never has enough; whoever loves wealth is never satisfied with their income. This too is meaningless.

So its left for everyone to decide weda it is or not.
