Pipeline is a surprisingly fun 3D pipe laying game. Presented as a kid's game, gamers will enjoy it as a light contest too. 4 players have colourful plastic sets of plumbing; straights, angles, T joints and capping pieces. Start from one side of the board, spin a spinner (or roll a special die) to select your piece and try to build a pipeline over to ending points on the opposite side. You can rotate your pipeline if required, but not backtrack, so when your neighbour's pipe gets in your way, you have to build over or around. First to connect wins.
