In Robots on the Line, robot parts move down two conveyor belts. Players take turns pulling robot parts (heads, bases, arms, hands, batteries, antennas and magnets). As players take robot parts, they build robots in front of them. Trading is always allowed and encouraged! If you meet a buyer's requirement, you sell it for money. If you meet the bonuses, get ready for even more cash! The game ends when all tiles are off the line or when a player has built 3 robots. The player with the most money wins!
