For the last 2 Pair Up releases, we took out the mute button from the game menu, and got some questions from our users as to how to mute the game sound. Here’s how: use your phone’s volume controller.
A bit more explanation as to why we made this change: the popup menu with 4 items (hint, shuffle, pause, and mute) takes too much estate: almost 1/3 of the screen, which blocks too much of the board. Reducing it to 3 items will allow them to fit in one line and only take 1/6 of the screen. Plus, less items in the menu will make it easier and faster for users to locate and click on the intended item.
