Miis are the only playable characters in single-player and online mode; in multiplayer offline, players can also choose between the Mario and Dragon Quest characters as well. Each computer character is ranked from S, A, B, C, D in terms of difficulty (S being the highest, and D being the lowest) which means each computer character has a predetermined difficulty. If the player beats either all the Easy Tour boards or all the Standard Tour boards, they will have the ability to switch the computers' difficulty from S rank to their normal rank.
