Lilliput match 3?

I'm a cryptographer in lilliput. I've played match 3 and there are these flower like objects to remove so I can remove phones. The flowers have 4 triangular spaces that turn purple. I don't know what I'm supposed to do to change them, I just make matches near them hoping. The result is I use so many moves that I don't have enough to get the phones. Any help is much appreciated.
