Title: Too hard to put down!
Review: I usually hate studying for test, especially when there's a lot of vocabulary involved. Looking at flash cards does nothing for me. But, I got caught up in the solving of the puzzles and forgot that I was studying. I loved the "cheat" buttons for when I just couldn't figure it out. The more I solved the easier the next puzzle became. I could not have mastered the test without it. What a terific resource. Thanks!
