The four-in-a-row challenge game

Get the drop on your opponent in a fast-paced game that puts your memory to the test!

It's simple: take turns dropping your colour marbles into the tubes one by one, and try to get four in a row vertically, horisontally or siagonally 0 while you block the other quy's moves. The trick is you both have to do it i the dark, because the tubes are hidden beind a shield. 

This game is a marble line-up challenge with a  twist...

and it's so compelling, you could lose your marbles!
