Each Category will contain a specific number of rounds. Each round will be locked besides the first round. Each round will consist of 9 multiple choice questions, with each question having a 13-second timer to complete. Each player will be given a specific amount of coins at the beginning of the game. At the end of the round, a winning or losing screen will be shown and the player will be able to earn some coins. Every round afterward will unlock automatically by answering all the questions correctly. The player will have to pay a fee of 10 coins to play each round.
