Sin it can only be for religious fanatics. For me, this is a great opportunity to have fun and win a good amount.
Yes. that's why we should not be involving religion if we are discussing this kind of things specially in gambling. If you believe that gambling is against your religion then you are committing a sin. As for me, gambling is for fun purposes and you are enjoying your life. But getting religion involved is a different thing because you will feel guilty everything you gamble because it is against your religion.
