Scrolls was originally conceived and developed by Jakob Porsér, who along with Mojang founder Markus Persson, intended to create a type of game that was currently missing from the market.

[5] The game revolves around the use of cards, or "scrolls", to work toward destroying three of the opposing player's five idols, which are static objects on either end of the battlefield.

[6] Once it becomes your turn, you either have 90 seconds to perform your actions (in multiplayer) or unlimited time (in singleplayer).

In July 2012, Scrolls moved into a closed alpha phase, with a small portion of those who signed up given full access to the game.

Additional invites were given out as the testing period expanded into an open beta phase.

[7] In June 2013, the game entered an open beta stage which allowed public purchase of the title.

[10][11] On 10 December 2014, Mojang announced that Scrolls would be leaving its beta phase to officially release the next day.

[12] Scrolls was ported to iOS, however Apple rejected the submission for release because of the game's account system which required players to register before playing.

The iOS version was ultimately cancelled once Mojang announced they would cease active development on the game in June 2015.

This allowed the developers to gather feedback on new features and perform balancing tweaks and bug fixes before they were officially implemented into the game.

They also noted that all proceeds from the game will go towards maintaining servers, which they confirmed would continue running until at least 1 July 2016.

[15] On 20 June 2018, Mojang released the title under its new name Caller's Bane as a free client configured to work with community servers.
