Differences are hidden between two images—can you find them all before time runs out? Maximize your browser window to maximize your look at the two images and use the hint system to narrow your search to find all the differences before it's too late!
The two images will have differences between them. Click the difference to mark off the change and then look for more. Look for changes of color, or objects that are present in one but not the other, for example.
There are four hints you can use to find differences, like the gauge pictured right. Use them whenever you can't find the last difference!
Work quickly! There is a time limit for every image. If you don't find all the differences before time runs out, you cannot make any progress.
