Ciudad de Palabras: Crucigrama App Reviews

I enjoyed playing this game however several time while playing a scam page saying I won an iPhone and this Did Not happen one time

it keeps doing it it tells me it will show a video and the screen goes black and I can only return to the game by exiting and when I return it loses my coins and it doesn't even show any video. Tambien . Also some words that there are in Spanish, when I type them the program doesn’t recognize them!
