When a character has more votes than the another one, he/she'll move to next level. After completing the level 4, he'll win. When a character has less votes than the another one, he/she'll be disqualified from the contest. Clicking a like button means you're voting a left-displayed character. Clicking a dislike button means you're voting a right-displayed character. If two characters have the equal votes in counting, the random character will be moved to the next level, while the another one will be disqualified.
