Huntsville is an “I-Spy”-like game where you have to find various objects in a crowded room and then click on them. I learned about it from the Game-EFL blog.
I have several other “genuine” online I-Spy games on my English for Beginners page under Reading. These are a little better for English Language Learners than Huntsville, since these I-Spy games have audio as well as text. But Huntsville can still be played and enjoyed by beginning English Language Learners.
I’ve placed Huntsville on the same page, but in a different section — at the bottom of Vocabulary.
