Challenge Land

Challenge Land (チャレンジランド) is a special land in Rhythm Heaven Megamix, which opens after clearing The First Gate. Unlike other lands, Challenge Land isn't part of the game's story.

Description
At Challenge Land, the player can board the Challenge Train (チャレンジトレイン) either solo (where they must pay the Challenge Charge (チャレンジ料金) of 5 coins) or with up to three friends (for free), where they ride through courses on the way to the goal, playing Rhythm Games with altered rules. The player is unable to play solo until after clearing Lush Tower. The player can play with friends via Download Play as well, but they can only receive rewards by playing the full version.

When the player successfully completes a course for the first time, they receive Flow Balls as a reward, which can be used to purchase Rhythm Games at the Shop.

Additionally, Challenge Land also contains the Perfect Campaign Headquarters (パーフェクトキャンペーンコーナー), where the player can attempt any ongoing Perfect Campaigns, as opposed to navigating to the location where the game normally is like previous games.

Rules
★ Score Goal ★: Reach the target score or higher! When playing with friends, all scores will be added together. ★ Life Goal ★: If you lose all hearts, you are out. When playing with friends, at least one player must survive! ★ Monster Goal ★: Keep hitting Aces to run away from the monster! Don't get eaten! Additionally, games may have their, sometimes the player has a choice between two games, and "Game Gamble" Courses choose randomly from a pool of Rhythm Games. Courses require the course before it to be cleared to unlock.

Trivia

 * While Saltwater World and Paprika World contain optional games from the Shop, there are no restrictions to unlocking challenges. This means some challenges can still be chosen despite containing rhythm games the player has never unlocked.
 * "Lockstep Lockdown" is the only course where the same game is played multiple times in the same course.
 * "Getting Vocal 2" is the only course changed for different regions. This is due to Lush Remix and Machine Remix having lyrics in the Japanese version, which were replaced with instrumental tracks in other regions.
 * "Wario...Where?" requires the player to clear all normal courses in Paprika World to unlock, while "Wario...Where? 2: The Sequel" requires those as well as "Wario...Where?" itself. The courses themselves also change the appearence of the Rhythm Games, replacing the main characters with those of WarioWare.
 * Tempo_Up_3DS.png uses a hidden multiplier, which can go up to 255%. A "Tempo Down" is also possible, which can go down to 1%, but it's never featured in the game.
 * A number of Rhythm Games never appear in any Challenge Train courses, those being Left-Hand Remix, Right-Hand Remix, Final Remix, Night Walk, Quiz Show, Big Rock Finish, Catch of the Day, and Love Rap, as well as the four Endless Games: Coin Toss, Sick Beats, Charging Chicken, and Clap Trap.
 * The Perfect Campaign Headquarters has three notes below the game's icon while a campaign is active. These turn off with each failure, and as such represent the three attempts the player gets at a Perfect. While having three attempts has always been a constant in the Rhythm Heaven Series, this is the first time this rule has been visually shown to the player.
