If you go to the 'Options' menu and select 'Settings' you will discover a multitude of things you can adjust to customise almost every aspect of the game so it plays how you want it to.
Note: Even if you have the latest most powerful phone on the market it is advised that you set the graphics quality to medium or less as the game tends to have heavy slowdown which will impact your score as the game is geared up towards speed and not strategy.
