The problem with playing clash of clans by paying for gems is that, you will soon find yourself having to spend far more money than you may have a budget for. Add to that the fact that you will have to choose between different games as playing just clash of clans may not be what you may want to do. There are many different games that may appeal to you from time to time, each requiring an equal amount of your time and perhaps money. So, you have to decide what you would prefer doing when you are faced with such a situation. Would you keep spending money on your different games till you can afford, or would you rather go for a hack?
I guess you may already be getting an idea on what I may be implying here and perhaps you may already know why I choose to go for a free gems on clash of clans and also why everyone else would choose to do the same. These things are important to give due consideration to as games hacks simply allow you to make your chosen games free in every single way as opposed to having to spend money towards it time and again.
