Nintendo Land

Nintendo Land is a launch game for the Wii U. It is a amusement park-themed mini-game collection consisting of twelve main games in total, referred to as "attractions," along with a pachinko-style minigame in the main plaza, with each attraction representing a different Nintendo game or franchise. Many of the multiplayer versus games utilize the Wii U Gamepad's screen for Player 1's vision. One of the main characters and tutorial for the game is Monita, a female robot who also makes cameos in various minigames. Miis are used as playable characters in all attractions.

Pachinko minigame
A pachinko-style minigame can be played by going to the central tower. In it, the player must drop coins from a moving Monita on screen in order to drop them through blue circles, turning them yellow. There are small and large white circles that break after a coin hits them enough times, and before they break, serve as obstacles that the coin bounces off of. There are also skull-shaped obstacles that instantly delete the coin. Once all blue circles have turned yellow, a decoration is earned. Once the game is exited, the decorations fly out of the tower in ? blocks.

Decorations
Decorations can be earned from the plinko minigame, which show up in the plaza. When interacted with, they have an animation, sound effect, and flavor text from Monita.

Trivia

 * Likely due to sharing development team members, the Nintendo Land Plaza appears to have been a predecessor to the hubs seen in Splatoon and its sequels. Both games present their modes and many other features through a space which can be walked through by the player, populated by the avatars of other players sharing Miiverse posts (a feature which was natively recreated for later Splatoon entries).
