Swap Factory

In this Game you can help Santa Claus sorting the presents in his factory.
Touch an object to swap it with another object or touch an empty space on the assembly line to place the object there. Try to place presents on the assembly line that has the same color.
For each correctly placed present you get 1 score. For wrongly placed presents you get 1 fail. If you reach 10 fails, the game is over and your score will be shown in your personal top ten list.

Sometimes you will come across special items, that have an effect that helps you once you swap them with another object or place them somewhere.
What will happen if you swap 2 special items of the same kind with each other?
Guess you will have to find out ;)
