Amazon (AMZN) - Get Report is continuing its investment in eSports with the announcement of the Champions of Fire Invitational, a casual mobile game competition hosted on its Amazon Appstore. 

The one-day tournament will be held Dec. 2 in Las Vegas, where 16 video game streamers will compete for a share of a $100,000 cash prize. 

Amazon-owned video-game-streaming site Twitch, Amazon.com and Amazon Fire TV all will stream the event. CBS Sports Network also will air highlights from the event 10 days later. 

Participants will compete across five "top rated" casual games, including Disney's  (DIS) - Get ReportCrossy Road, Bloons TD Battles, Pac-Man 256, 8 Ball Pool and Fruit Ninja Tournament Edition, Amazon said.

The move represents Amazon's latest foray into the gaming world, a venture that was largely kicked off by its $1 billion acquisition of Twitch in 2014. 

Amazon is capitalizing on a market that continues to expand: The eSports industry in 2016 saw its global audience increase 13.3% year over year, according to the Casual Games Association.

"Competitive video gaming has seen huge growth, and we see tremendous customer value in expanding the tournament experience to include the casual mobile games played by millions of people today," Amazon Appstore Director Aaron Rubenson said in a statement Monday. "The Champions of Fire Invitational will see some of the top gaming pros square off in the same fun games our customers can download and enjoy today from the Amazon Appstore."

Amazon Game Studios, which came out of Amazon's acquisition of game developer Double Helix Games in 2014, in September released three games with extensive support for Twitch live streaming. 

Earlier this year, the Seattle e-commerce company launched Lumberyard, a platform monetized through Amazon Web Services that allows users to develop games for PCs, Microsoft's  (MSFT) - Get Report Xbox One and Sony's  (SNE) - Get Report PlayStation 4.

Additionally, Twitch in April introduced the eSports Championship Series, a "professional league" of eSports gaming that allows co-ownership among teams, the league's website notes.  

Twitch has more than 1.7 million active streamers, with 100 million viewers who watch about 421 minutes of content per month, according to GeekWire

Amazon shares on Monday rose 2.6% to $780.
