Some fun "Transformers 3" online games include "Transformers Quest" and "Photo Mess - Transformers." As of 2015, these and other Transformers games are available to play for free.
In "Transformers Quest," players choose between one of three worlds, where they must find the planet clues to locate the planet key and save the day. Players alternate between walking, driving and flying their transformer to gather up clues and energy cubes. It's a timed game, so players need to work quickly.
"Photo Mess - Transformers" encourages players to take squares of a photo from the "Transformers" movies and put them in the correct order to see an image. Players click on two squares of the photo, and they change positions.
