The developers of clash Royale might provide the game to download for free on multiple platforms including IOS, Android, Windows and more however they are not going to provide you with more gems and coins for free which means that this game falls under the freemium category of games that not only ask you to spend money over and over again in order to get gems and coins but also ask you to pay for certain upgrades in the game so that you can continue to play the game effectively.
Although there are a number of different ways that you can purchase coins and gems you can get them for free using a hack and you should remember that you should always make sure that the clash royale gems hack you use is safe and will not damage your device or risk it in anyway.
When you choose a hack for your device you need to ensure that the hack is an online hack rather than a software based hack because anything that is in the form of software is risky because there is always the risk of a virus that could enter your device and damage it permanently. When you use a hack that is in the form of software this automatically voids the warranty of your device because you need to jailbreak the device in order for you to be able to install this. It doesn’t really make sense to do something like that because you are not even sure whether or not the hack will work and you have to jailbreak your device before you install the hack. Always make sure that when you choose a hack you pick one that is online so that it becomes very convenient for you to be able to get your unlimited supply of Gems and coins for free.
