To start a new game on the Toad Kingdom board, you must select "Play" on your main screen and then "Toad Kingdom" from "Game modes".
Once you do, a new pop-up window will open from which you can choose your opponent to finally start the game.
This board will challenge you to get 15 mushrooms and reach the King Toad before your rival to achieve victory. For each correct question you answer, you will get a mushroom.
If you reach the King Toad and you have not obtained the 15 mushrooms, he will challenge you by serving as many questions as your missing mushrooms to reach the required number. For example: if you arrive with 10 mushrooms, you will have to answer 5 questions correctly to get the missing ones. If you answer them correctly you will get the victory, while if you answer incorrectly you will have to return to the beginning of the board to get the missing mushrooms and climb again.
Although this board can be quite a challenge, it is important that you know that you will be able to find a large number of coins and chests with rewards along the path, as well as obtain a greater prize for winning the game.
