The sophistication of the game interface varies from site to site. All sites have a board similar in appearance to the Jeopardy! television show, with a list of categories across the top and boxes with numbers (representing points, not dollars like in the TV version) in a grid below. Some sites have just the bare-bones board, while others let players choose characters to represent themselves. In some cases, customization of characters can be very detailed, down to individual facial features.
Players click on a number, representing points available, to reveal a question. On the television show, contestants reveal answers and have to supply questions. But in these math contests, game play is often more straightforward with students answering questions rather than the other way around. Some games give players multiple-choice answers to select, some have a box to type in the answer, and some just display the correct answer without taking input. Games accepting input calculate scores automatically. Otherwise, players have to keep score for themselves.
Games cover a range of skills, from basic to advanced. Popular topics are: the parts of fractions; fraction addition, subtraction, multiplication and division; and converting fractions to decimals. Some games use straight-forward category names, while others emulate the cuteness of the television version's names, with categories such as "Crazy Conversions" and "Difficult Definitions."
Teachers can create their own Jeopardy! fraction games using tools and instructions available online. Some games require teachers have access to PowerPoint, while others can be created directly on a website. The web-based games are easier to create but require teachers make their games available online for others to use.
