Can I get some help with Xploing Boxes Level 18?

I am STUCK on this level and anyone out there can help me to solve this??

I downloaded the game just to see what could be the problem.

Level 18

First, use your first two taps to destroy the encircled purple box.

After that, you're gonna be left with these two red boxes and you're free to destroy whichever one.
