Coincentration

Coincentration is a Super Mario 64 DS mini-game where Wario punches a Moneybag and coins fall out of the sky into Brick Blocks.

The player must tap the bricks the coins fell in with the stylus. If the player taps a brick that has no coins, it's Game Over.

It later appeared in New Super Mario Bros. as a multiplayer and single player game.

In the multi-player version, the same thing happens, but each player takes turns choosing a block. If the player taps a block with no coins, the block will break and the player will lose coins. Once all the coins are found, the person with the most coins wins.

In-Game Instructions
''Pay attention to where the falling coins land. Tap the blocks to retrieve the coins. Choose wisely: if you pick the wrong block, your game will end.''

Trivia

 * The title of this mini-game is a portmanteau of Coin and "concentration".
