how many levels are there in new super mario bros wii
New Super Mario Bros. Wii The game contains eight worlds,[8] with a secret ninth world also accessible by locating all collectibles in each stage.[21] Levels are accessed via a 3D world map;[16] completing a stage unlocks the next one, with multiple choosable paths sometimes available after completing a stage. Each world contains two boss levels — a midway fortress and a castle at the end of the world — where the player battles a Koopaling.[12][22] In addition to levels, there are also "Toad Houses" located across the map in which the player can play a short minigame to earn extra lives or items that can be equipped from the map screen.[23] Map screens also often have enemies roaming them in certain dedicated areas which initiate a "mini-boss" fight when encountered that, when won, will award the player with items. At certain points, a Toad will appear trapped in one of the previously completed levels, and the player can choose to rescue him from a block and carry him safely to the end of the stage in order to earn additional lives.[24] Every course contains three Star Coins which are hidden in hard-to reach areas.[24] These can be spent on hint movies which show off tips and tricks for the game, including the locations of secrets and methods for getting infinite lives.[25]
