Amazing game,but

Its a really good game fun and active but when I reached level 27 it gave me 1000 coins and gems but when I left the resent game I had leveled up in it went straight back to normal my 1000 coins and gems where gone. So I just wanted to know if the coins and gems were glitch or I was supposed to really get 1000 coins and gems. But other then that it is a really amazing game.
