Wheel of Fortune Deluxe features 2,000 puzzles created by the TV show writers, a very realistic game stage, and a road-trip mode where you play in venues across the USA. Vanna White is not included (probably due to her successful lawsuit against Samsung). You can win "valuable prizes" like trophies and virtual cash with which to amaze your virtual friends.
If you're a fan of more cerebral game shows, you'll love Jeopardy! Deluxe. The TV show writers came up with over 3,000 clues, and the game has very realistic play including Daily Doubles and Final Jeopardy! questions.There's a multiplayer mode so you can play against up to three of your friends.
To try out these games on your Mac, you can download demos from the Freeverse website for free. The games are $19.95 each.
