Bob-omb Breakers

Bob-omb Breakers is a Tetris-like 4-Player minigame from Mario Party 4 and a Puzzle minigame from Mario Party DS.

Mario Party 4
Each character starts with their own column, three squares wide and nine squares high. Two by two, blocks will fall from the top of their column. Players must use the falling blocks to earn points by making groups of three or more similar-colored blocks, which breaks them. If the blocks break in such a way that one set falls to form another group of three, a chain is formed and even more points are scored. Sometimes, Bob-ombs will fall; surrounding a Bob-omb with blocks causes it to explode and take out all the blocks touching it, scoring points for each one. The player who gets to 100 points first wins the game.

Players are not restricted to placing blocks and Bob-ombs in their own columns. Any player can place any block anywhere, but they will get points only if they are the one who completes the group of three. As a final note, if any player's column gets completely filled up, that player cannot participate until some of their blocks are cleared by other players. If three columns are filled up, the player whose column was not completely filled up wins, regardless of points.

Mario Party DS
In Mario Party DS, there are a few changes. The bottom screen shows the entire action, while the top screen shows a tip about surrounding a Bob-omb. In addition to that, there is an "all clear" bonus that gives the player an additional 1,000 points. Each match is worth three points times the current level number. During the game, the sides will close, blocking any extra pieces.

The two-player version has the same rules as the Mario Party 4 version.
