As you advance through the game's squares, you will meet the different Trivia Crack characters: Tina, Bonzo, Tito, Pop, Hector and Albert. To obtain victory, you must rescue them by answering correctly when you find them.
Once the character is obtained, you can view it at the top of the game screen next to your username. In the same way, you will also be able to see the number of characters that your opponent has managed to rescue.
