If an employee spends work time on personal activities or entertainment, the employer will obviously not like it. And it makes no difference whether you are gambling, scrolling through your favorite social network or something else. In your free time you can do whatever you want, but at work you just have to spend all your time on work.
Whether to follow it or not everyone decides for himself, but we all know how nice it is to do our own things.
You can bet on cricket / football matches in offices but you should know that you are coming to the office to work, and normally in offices the television is hanging on the wall and also on where a cricket match or news or sports match is playing, and at the same time if you watch cricket at the office so you can't concentrate on your original work, and you also can't complete your work and your work slowly become a pending work.
Yes, if your work is finished and you have free time wait for a break or holiday so you can see and bet on it. You can do all the things in the office if you just focus on the work that you come to office.
