Clash royale released in late 2015 in western countries and came to india in february.supercell actually had this game concept long ago even before clash of clans.
thie game needs a moderate internet connection.layout and designs changed very little since its release.every key functions very smooth.
this game is a pvp real time multiplayer game.there are many cards called common, rare, epic, legendary according to their obtainable rate.by playing online battles you can win chests which gives you cards to unlock and upgrade and that needs time.chests can also be opened fast with gems.cards can be upgraded or bought from shop with coins.after winning some battles you can join clans where max member capacity is 50 .you can also request card from your clanmates and also donate to get gold and xp to upgrade your xp level so you can upgrade your king tower and two archer towers.you can also play friendly battles with your friends but that does not give you chests.
in an online battle there are two sides.you have 3 towers to defend you can choose any one card at a time to play while you will have four cards in your hand.you have to build a deck to play which consists of 8 cards.
oh I forgot to mention that cards are of many types like troop , spell, building.
this game is very addictive .i played once like there was no day and night.but now this game is becoming boring.many players left this game because of supercell, its developer.they only know one thing thats money.they makes players bound to pay for the in game purchases.players are buying gems and deals to improve their game.
I am not fond of this idea .so I quit.
