Keep in mind that you can select the language in which you want to play by accessing the "Settings" menu. To do so, you must click on the gear icon at the top of your home screen.
Upon entering, you will find the language option under the sound, music and support icons. You will be able to open the drop-down menu to select the language of your preference.
Remember that changing the language from here will change both the language of the game interface and the language of the questions.
