Spring 2015 Challenge

Thanks for playing the Spring 2015 Lost Tribes Challenge.

Stay tuned for a new challenge in Summer 2017

For five days we posted puzzles for you to solve. At the end of the challenge one student and three classrooms submitted the correct answers to all five puzzles and were entered in a random drawing for autographed books, classroom sets, and or a Skype visit from the author.  In the end, we had 1250 hits on the website.


1. Mrs Weien’s class at Williamsburg Elementary (Winner of classroom set and Google Hangout session with the author)

2. Mike Gingerich (individual winner of an autographed book and FaceTime session with the author)

Here’s the winning class posing with books that arrived just after their Google Hangout session (it was a surprise).


Curious to see how these extremely bright students solved the challenge? You can see photos of their solutions here:

You can still find the original puzzles and hints here if you want to play just for fun. (no book purchase is necessary to solve them). Just remember not to peek at the answers until you are done.
