Crazy Cogs is an 1-vs-3 minigame found in Mario Party 3. This minigame is similar to Shock, Drop or Roll, from Mario Party 2,
The player who controls the large cog has to make the other three players get hit by Bullet Bills while the other three players on the large cog have to avoid being hit by Bullet Bills. If the player makes all the three player get hit by Bullet Bills, that player wins. But if even one player in the player-field avoids being hit by Bullet Bills, the three players win.
