Follow the link to play Alien Escape:
You will see an alien waiting to cross a gap in the road. Next to the alien is a scrambled word and a picture. Click the letters in the correct order to spell the word in the picture, they will drop down to build a bridge across the gap. If you spell the word correctly the alien will walk across and climb up to the next gap. If the alien does not move, click on the letters to send them back to the top and try again.
If you're looking for a real challenge, play Sentence Substitution.
At the bottom of the screen you will see a sentence and four words at the top. You can replace a word in the sentence with any of the words at the top, simply by dragging it down over the word you want to replace. If you read the new sentence out loud, does it still make sense? How many of the words at the top can you use to make a new sentence? In some cases you can use all the words. In others, one of the words will make the sentence quite funny.
