Piece Out

Piece Out is a Duel minigame in Mario Party 5 and a Puzzle minigame in Mario Party DS. The title is based on the saying "peace out." This minigame features one-minute, three-minute, and five-minute modes; in all modes other than Free Play, the duel is contested under the standard one-minute mode.

Gameplay
The object of the minigame is for players to fill their respective spaces with blocks carried out by a conveyor belt. There are several types of pieces, all of which come in four colors: red, yellow, green, and blue. The types of pieces are single blocks (one block), double blocks (two blocks), triple blocks (three blocks), quadruple blocks (four blocks) in line form or rectangle form, and double triple blocks (six blocks that consist of two rows of triple blocks). If the player picks the wrong block(s) and wants to get rid of it/them, they must hover the block(s) over the trash bin area at the bottom of the player's field. This way, the player gets rid of this/these block(s) and is able to grab a new one. Once the field is completely filled, the pieces disappear, giving the player more chances to fill the space and get more points. Points are based on the size of the area of the same-colored blocks, and they are not awarded until the space is filled. Filling all the blocks in one color awards 13,500 points in the Mario Party 5 version and 35,000 points in the Mario Party DS version. At the end of the time limit, whoever has more points is declared the winner. If both players get the same number of points, the minigame ends in a draw.

In the Mario Party DS single-player version, the player has one minute on a level to fill their grid. The player must fill the grid completely to complete a level, and the minigame ends if time runs out on any level. The multiplayer version follows the same rules as Mario Party 5, and it allows time settings of one minute, three minutes, and five minutes.

Due to there being only six digits, the maximum number of points a player can accumulate is 999,999.
