Riot Games' new free-to-play card game Legends of Runeterra has already been a big hit on streaming platform Twitch.

That's according to data and research site SullyGnome, which says the title has been watched for 2,594,707 hours at the time of writing. 5,978 hours of gameplay have been broadcasted so far to an average 36,037 viewers. The maximum number of viewers so far has been 236,450, too.

For the last three days, Legends of Runeterra is the eighth most-watched title on Twitch.

The new title was announced during Riot's League of Legends ten year anniversary event, with a closed beta rolling out on Wednesday, October 16th at 2am BST which is running until October 20th. The company also revealed a number of new games alongside Legends of Runeterra, including a mobile version of auto chess release Teamfight Tactics and an update to the PC edition called Rise of the Elements.

Meanwhile, League of Legends is coming to both mobile and console with a new Wild Rift edition of the hit MOBA. Then there's three untitled games, simply known as Project A, L and F.

Project A is a PC character shooter, while L appears to be that fighting game title that Riot has been working on for some time. Not much is known about Project F as of yet. Oh, and there's an animated series based on League of Legends called Origins coming to Netflix, too.
