I played Mysteryville first. Mysteryville works great all the way through. I was having a blast playing Jewel Quest. You have to find hidden jewels and coins in each puzzle in addition to the hidden items. It actually has a storyline you follow and it's okay. However, when you get to the last location the "Puzzle" game where you have to turn all the squares to gold by inserting preselected "blocks" of squares and turning on switches; when you run out of time, instead of going back to the map, it locks up. It just freezes, you have to turn the DS off. I tried it 4 times, 4 times it locked up. I tried it in a different DS twice, still locked up. Went to Activision's website; it says to return it to place of purchase for an exchange. I really hate that, it was a fun game and I enjoyed "racing" against the clock.
No: I don’t recommend this product
