Jeopardy on DS is exactly like the real game show Jeopardy on NBC. You can play Jeopardy in an easy, medium, or hard mode, or mix it up in the custom mode. According to what mode you picked, you answer questions/clues on a keyboard or a list of 3 multiple choice answers. You are timed in each mode. When you choose your difficulty setting, you can sign your name. You can answer over 2,400 questions, or what they call it in the game, clues. The game has Jeopardy!, Double Jeopardy!, and Final Jeopardy!. The game also has the clue crew, daily doubles, and an audience in the backround. You can only win money by answering clues correctly and getting the most money out of your opponents in the entire game. You lose money when you get a clue wrong. You also get to wage your money during the daily doubles and Final Jeopardy!. All the money you collect can be used to buy clothes for yourself and Alex Trebek. If you've ever seen Jeopardy on TV or you know pretty much about it, this game is like the exact game show.
