The easiest way to get people to do something new is to make it free, offer prizes, and make it similar to things that they are used to doing. FanDuel’s Tweetball fantasy football is a simple game that easily meets all of these criteria, while creating a simple and elegant fantasy football game that is played exclusively on Twitter.

FanDuel is hosting this game to drive traffic towards its main suite of pay-to-play fantasy sports games that you can find on its site (See: FanDuel Launches Fast Head-To-Head Fantasy. Aside from finding a simple, low-cost way to market itself, Tweetball may ultimately be a product that FanDuel can build a business around. It is easy and fun to play, does not require fantasy players to change their behavior (as long they tweet), and is easily accessibly by anyone. Plus, add in the potential for the game grow via a viral expansion loop, and FanDuel ultimately may have a success on its hands.

To play Fanduel’s weekly fantasy football twitter game, a player tweets a quarterback, running back, and wide receiver and includes the “#fanduel” tag and a link to the game (as pictured above–pretty simple, eh?). The team with the most points each week wins a Fathead of its choice.

Tweet and win!

From the founders of Hubdub, comes a new fantasy sports site FanDuel, which is geared around daily head-to-head fantasy games. Hubdub is an interactive site where users predict the news, so fantasy sports is a good tangent for the company.

To play FanDuel, fantasy players select the players that they think will score the most fantasy points for that day. At this time, only fantasy football and fantasy baseball are supported, but expect that to change if FanDuel grows. Currently, players can play for free, but the game’s big allure is the ability to play for cash prizes, with players able to enter a cash league for as little $5. For each $5 entry fee, a player can win a $9 prize. He who scores the most points wins the game and gets paid instantly. If you sign-up and add funds right now, FanDuel will also give you an additional $10 bonus.

Short-term fantasy leagues are definitely a growing market, as evidenced by the recent launches of SnapDraft and Instant Arena. FanDuel is keeping their game simple by focusing on head-to-head match-ups, and making game play very straightforward.

Congratulations to Hubdub with the launch of FanDuel, and good luck with the launch.
