Coincentration

Coincentration is a minigame that first appears in Super Mario 64 DS. It later appears in New Super Mario Bros. as a single-player and multiplayer Puzzle minigame. Its name is a portmanteau of "coin" and "concentration."

The music that plays in this minigame is an arrangement of the Underground Theme from Super Mario Bros. The minigame's name is used as the title for an arrangement of the Underground Theme in Mario & Sonic at the London 2012 Olympic Games and its 3DS version.

Gameplay
The game starts with Wario on the top screen standing next to a Moneybags; he punches it into the air, and 40 coins then fall down and make their way into the Brick Blocks as the Moneybags bounces offscreen. The player must use the stylus to tap the bricks containing coins. If the player taps a brick with no coins, the game will end. The highest possible score that the player can obtain in this game is the "perfect" score of 40.

In the multiplayer version in New Super Mario Bros., the basic premise is similar, but each player instead takes turns choosing a block. If a player taps a block with no coins, the block will break, and the player will lose two points. It is possible to have a negative score in this mode. Once all the coins are found, the player with the most coins wins.

In-game instructions
''Pay attention to where the falling coins land. Touch the blocks to retrieve the coins. But if you choose the wrong block, your game will end.''
