Marbles

Marbles drop one at a time into six glass pipes. At each junction an arrow says whether a marble goes on down or turns along the cross pipe, and one button flips every arrow at once. Slide the red and blue buckets to catch each marble in its own colour. Forty drop on each level, you need twenty to go on, and each new level is faster with more cross pipes.

Controls: Left and right slide the buckets; a side button flips the arrows.
