There are lots of different kinds of bottles in the factory: Yellow, red, green, brown, orange and clear. Each player has his own case, where the different bottles are mixed - with exactly 4 of each colour. A handful of bottles are drawn from the bag. If there are fewer than 4 of a kind, they are placed on the transportation track, but if you are lucky and draw exactly 4 of a kind, you may place them in your case immediately. If you get more than 4 of a kind, you will have to return that colour to the bag. The more bottles you draw, the bigger the chance of you geting your case filled, but you also increase the risk of drawing to many. If you already have bottles on your transportation tracks (from last time you drew), you will add those to the next handful you draw.
