I often hear parents ask how much time they should be giving their kids to play their various games online, including but not limited to clash of clans games which have proven to be getting a lot more popular than they were probably perceived to be capable of. The thing to remember is that, kids tend to have their own hobbies and interests which means, being a kid does not necessarily signify being irresponsible requiring guidance at every step of the way. In fact, what you will find is that, most children do not even have passion for online games which just goes on to prove the point that I was trying to make.
If you have kids at home, you may know better how much love they give to online gaming and hence, it may be in your best interest to hack clash of clans and make the game free to play. And this is a good thing because kids should really only be playing games on the internet instead of doing other things such as chatting as these could prove to be a lot more risky. If however, your children appear to be spending too much time gaming, it would be best for you not to just refuse them from doing so as it may not go very well that way. Instead, introduce them to other more constructive activities so that they could share their spare time between different things.
