Check Out Line

I just need to pick up a few things at the market. Some cheese. Bread. Milk. Pickles. Hey, these new mustard and cinnamon potato chips look good. Better get those. Oh, and some English muffins. Yea. OK. Time to check out. Rats! Look at the size of these lines!

The supermarket has twenty check out lines and plenty of waiting. Your goal is to help the different colored shoppers get through the line by clicking on them. Clicking on shoppers that are next to other shoppers of the same color, either horizontally or vertically, will set them free. Additionally, any shoppers of the same color next to them will also be set free. The more shoppers you help with a single click, the more points you will be awarded. As you clear away shoppers, the next in line will move forward, providing you with new groups to click on. As you clear aisles, they will close and all the lines will move to the left. Try to clear as many shoppers as possible in large groups to score the maximum number of points.
