Clash Royale is the spinoff from Clash of Clans from Supercell which, with the same cast of characters, presents us with a different strategy game: instead of being in real time like CoC, it combines the tower defense genre with card role-playing games. The gamble worked out well and CR has become one of this videogame development studio's biggest hits.
A private server for CR
The issue many Clash Royale users have with the game is that be able to fully enjoy it they need to progress and unlock many items or, if they don't, to spend real money to get them. That's not the way it works if you opt to use a MOD like Legendary Royale.
Here we will be able to have all of the resources offered in the strategy game in its multiplayer matches: cards, characters, attacks, powers... and all without spending a dime. So, OK, where's the catch? Well, simply that we are talking about a private server and this means that you are not playing in the official Clash Royale and those other LR users will have the same resources and possibilities as you.
But, it is a good way of discovering everything that awaits you in Clash Royale and to go sifting through things in order to find the best stuff for your matches in the long run.
