Please pack all colored boxes at the bottom of the page in the container using "drag and drop". Try to minimize the height used (indicated by the dotted red line). You can touch an item as often as you want. But be aware that once you click on the next item, you will no longer be able to change the position of all previously stored items. Once you have successfully placed every box, you will be able to continue with the next round by clicking the button below.
