And idea πŸ”ŽπŸ’­ That's so Random

So I've been doing cross words to extend my vocabulary in the meantime until I get into college. My question involves this crossword puzzle 
It just says word search but it's contains many different word searches with different categories ,but is there a way to transfer the gold coins so I can play more games? Normally you pay with the green coins. It's like I can't do much with the gold coins. I choose not to skip ahead of the game so is there a way I can transfer them into green?
