Seattle’s FlowPlay has launched Dynasty Football, an online fantasy football strategy card game.

The title aims to capitalize on the 51.6 million people in the U.S. who play fantasy sports games (according to Fantasy Sports Association). Market researcher Ipsos estimates that each player spends an average of $465 on fantasy sports competitions, up from $95 in 2012.

Created for fantasy football fans and collectible card game enthusiasts, Dynasty Football combines real-world stats and player drafting mechanics of fantasy football with the fun of head-to-head card matches. The game is the fifth free-to-play social sports wagering game from FlowPlay, whose games have been played by 75 million people.

In the game, players draft their decks from a set of more than 350 cards. The game is a fast-paced head-to-head card title designed to simulate a virtual football game. The goal is to advance the ball to the opponent’s end zone. Each player has 30-card offensive and defensive decks. Players have to build a team based on a player’s real world stats from the 2015 season. If the player card trumps the opponent’s card, the down is won. You can also win big plays or throw a player for a loss.

“Collectible card games have become increasingly popular over the last two years, and we saw an opportunity to bring our expertise in casual fantasy sports games to this growing market,” said Derrick Morton, CEO of FlowPlay, in a statement. “Dynasty Football brings together the fun of fantasy and strategy of digital card games into a one-of-a-kind, social experience.”

FlowPlay’s suite of titles alongside Vegas World Sports Book, 5 Card Draft, All Star Daily Fantasy and Ready Set Bet. All games can be played in FlowPlay’s flagship massively multiplayer online game (MMO), Vegas World. FlowPlay was founded in 2006 and is primarily funded by Intel Capital and the creators of Skype. The company has 57 employees and it has raised $7.2 million.
