<P> A traditional side - scrolling platformer, New Super Mario Bros. Wii features gameplay similar to previous side - scrolling entries in the Super Mario series . In single - player mode, the player controls Mario and must complete levels, which are filled with both helpful items and harmful obstacles, by maneuvering him to the large flag pole at the end of the stage . The game can be played with the Wii Remote held horizontally, or with the Remote and the Wii Nunchuk . Controls are similar to those of previous side - scrolling Super Mario games; the player can run, jump, and perform additional moves returning from New Super Mario Bros. such as wall kicks, ground pounds and double and triple jumps . New to Wii are several abilities making use of the Wii Remote's motion control features; the player can shake the controller in order to perform various different actions, such as a short spin jump which kills enemies, a mid-air twirl that can be used to sustain air time, and the ability to pick up, carry and throw certain objects . Certain areas within levels, such as specific platforms, can also be manipulated by standing over them and tilting the Wii Remote . Certain levels are set underwater, and involve swimming as opposed to ground maneuver . </P> <P> In addition to gold coins, which the player can collect to earn extra lives, levels contain power - ups encased in floating blocks which aid Mario in his quest . Several power - ups return from previous Super Mario installments; the Super Mushroom makes Mario increase in size and allows him to take an extra hit before dying, the Fire Flower lets Mario shoot fireballs at enemies, and the Super Star gives the player temporary invincibility and increases running speed . The Mini Mushroom, which reappears from New Super Mario Bros., causes Mario to shrink in size, letting him jump higher, run on water and fit through small spaces, albeit while making him vulnerable to enemies and other obstacles . New power - ups include the Propeller Suit, which allows Mario to fly for a short time by shaking the Wii Remote . Both the Ice Flower and the Penguin Suit give Mario the ability to shoot balls of ice which freeze enemies into large ice blocks that can be lifted and thrown, whilst the Penguin Suit additionally allows the player to slide along the ground and across water as well as giving them more fluid control on ice and in water . Yoshi appears prominently in the game in certain levels and is able to eat, swallow and spit enemies and objects, and flutter for a period of time similarly to Super Mario World 2: Yoshi's Island . </P> <P> The game contains eight worlds, with a secret ninth world also accessible by locating all collectibles in each stage . Levels are accessed via a 3D world map; 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 . 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 . 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 . Every course contains three Star Coins which are hidden in hard - to reach areas . 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 . </P> <P> The player begins the game with five lives, but more can be obtained through a plethora of ways including collecting power - ups and playing minigames . Losing a life will return the player to the map, and losing all lives results in a game over, forcing the player to return from their last save point . Most levels contain a midway flag, which, if reached and passed through, the player will return to after dying and returning to the level . Certain levels contain hidden alternative exits leading to a flag pole with a red flag . Reaching this goal opens up a path on the map leading to a hidden area, which can contain new stages, Toad Houses, or warp cannons which allow the player to skip forward to other worlds . </P>
