Challenging, interesting, fun puzzle game … I could go on. HOWEVER, when the ad inevitably pops up (and the sound to my phone is on) I receive a BLAST of ad music! EVEN WHEN I turn off both the sound and music in the APP settings, the sound STILL comes through with the ads. Of course, I want to leave the sound to my phone on so I can receive alerts … you know, texts, phone calls, other notifications. And, occasionally, I will play a game when on a call (eek!). But, when the ad music comes blaring through, I am diving to turn off the sound on the ad. Not attending to the ad! Annoyed with the ad. But, ho! I can go to my OTHER game apps that allow BOTH the game sounds and the game AD sounds to be turned off. Happy player! Glancing at the ad, noticing the ad, and not having to hear ANY of the ad sounds. Not annoyed, not turning off the game, and not going to another game that allows play without game sounds/music AND without ad music.
I gave the game three stars with two stars off for this easy fix.
