Scrolls is the next game from Minecraft studio Mojang that promised Linux support back in 2012. Two years later they have just pushed out an experimental Linux build.
Liam covered it rather a lot (latest article on it linked). It's great to see that Microsoft buying Mojang hasn't yet meant Mojang giving Linux the cold shoulder, and I hope they continue to support us
I have been unable to play it in Wine, so this is fantastic news.
Scrolls is a turn-based battle game played out with a deck of cards that come alive on the battle-board. There are different sets to collect, and you can customize your deck 'till you drop.
