That's because HYPER is a PoS (Proof-of-Stake) coin.  So technically, HYPER can't be mined.  What CoinKing allows you to do, is mine other coins in HYPER's place.  CoinKing does this through automatic coin-conversion, so what you have to do is go into the auto-conversion settings in your CoinKing account, and set it to auto-convert all other coins to HYPER.  Then, whatever coins you get through mining, on whatever algorithm you choose (if you're mining with graphics cards, don't mine SHA or Scrypt…would be a waste of time & electricity), will be automatically exchanged for HYPER and credited to your account.
Also, since HYPER is PoS, you don't want to let your coins sit on CoinKing for too long.  Get them into your real wallet, so they can start earning interest!
