To start a new game in classic mode, you'll need to tap on 'New game'. Once you do this, a screen will be displayed and you'll have to select the language and the type of opponent you want to play against.
The game is available in a number of languages: Spanish, English, French, Italian, Portuguese, German, Turkish, and many more. You should pay attention to the language you select, since you won't be able to change it once the game starts.
Opponents can either be either Friends or Random Opponents. Once you have selected the language and the type of opponent, you'll have to tap on 'Play' for the game to begin.
During your turn, you'll have to get as many characters as possible.
In order to do this, you'll need to answer three questions from any category and the crown question of the character you chose correctly. You can also fall in the crown slot and automatically answer the question in exchange for a character.
You'll have 20 seconds to answer each question. You'll also have two days to play your turn.
The game will end when one of the players gets all 6 characters, but it can end sooner if one of the players quits or doesn't answer in time. In either case, the other player will win the game, regardless the number of characters they have.
The game can be rejected before it starts, and that will not affect the statistics of either player. Neither will lose nor win the game by doing this.
