I can still remember spending hours as a kid playing "spot the difference" games with a pen and paper in my activity books. When I got a little older, I used to steal the newspaper to play it before my parents got down to the crossword. Now, thanks to BBerryGo, I can play right on my device, any time I want. The latest game from the same company that gave us apps like Show Me the Images, Photo Quest is a simple, very time-consuming game. You will be presented with two photos, and you need to spot and mark the changes between the two. The game will randomly choose a set of differences every time, so you'll get a lot of replay value out of each set of photos, and the timer ticking down adds a great challenge to the gameplay. Online leaderboards allow you to compete against others trying to post the highest score, a feature I'm happy to see is making it's way into more BlackBerry games. Available in the CB store for $4.99 for all devices running 4.5 OS and up.
