Sports Jeopardy is available in the App Store for 99 cents.
EDIT: Had a chance to play it, and here's my good and bad-
GOOD:
-The entire presentation is nice.
-The game moves fast.
-The questions are challenging.
-Unlike Jeopardy games in recent memory, you can type in your answers.
-Your end of game score is multiplied (for Achieve,net purposes only) and really gives you a nice boost should you make the game harder in any number of ways.
BAD:
-It's still a little buggy, but it matters a lot because it keeps you from actually playing the game. Although I was connected to the Internet, the game consistently game me "no connection" errors that slowed my progress through the menus. It took six times for me to get into the game.
-There are in game power ups- not really my cup of tea for a game like Jeopardy, but it's a specialized version and I'm sure it'll bring more people into the fold.
All in all, a pretty good effort. I wouldn't mind if they updated the two/three year old regular version with this format.
