Bob-omb Breakers

Bob-omb Breakers is a Tetris-like four-player minigame from Mario Party 4. It reappeared in Mario Party DS as a Puzzle minigame. Each character starts with his or her own column, three squares wide and nine squares high. Two by two, blocks will fall from the top of their column. Players must control the falling pieces to make groups of three or more similar colored pieces. Doing so will break them and earn points for the player. If the blocks break in such away that one set of blocks 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 taking out all the pieces touching it, scoring points for each piece. This minigame can be compared to Block Star from Mario Party 6. In Mario Party 4, 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 only get points 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 his or her blocks are cleared by other players.

In the DS edition, there are a few changes. The bottom screen shows the entire action, while the top screen shows a reminder of surrounding a Bob-omb. In addition to that, there is an all clear which gives the player an additional 1,000 points. Each match is worth three points times the current level number. More combos means more points and during the game, the sides will close, blocking any extra pieces.
