This game makes waiting in the Check Out Line fun! Click on carts that are next to other carts that are the same color and all those carts will disappear. Continue clicking until all the carts are gone or there are no more moves. The more carts you remove in a single move the more points you earn.
The supermarket has 20 check out lines and plenty of waiting. Try to help the shoppers get through by clicking on them. If you click on a shopper that is next to another shopper of the same color, either horizontally or vertically, they will be set free, as well as the shoppers of the same color next to them. 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, but also try to clear them away in large groups to score the maximum number of points.
