A version of Indev 0.31 was released on December 23, 2009.[1]

This is the first version of the Indev development cycle of Minecraft, and the first paid version of Minecraft (available at €5.00), as Notch released this version for paid users to test out new features.[1]



Rana.png Rana
  • Has the player's shadows.
  • All other mobs no longer spawn.


  • Added dynamic lighting.
  • There are 9 different light levels.
    • Due to this, caves have now been made darker.
  • Oddly, blocks in the inventory and hotbar are affected by lighting - upon generating a new world they appear dark, then go back to normal brightness after a while.



  • This version, as well as 20091223-2, is in Creative mode.
  • Survival mode[verify]
    • The player now spawns with 99 stone slabs, stone, water blocks and lava blocks (leftover from an unreleased Indev 0.30 version)
    • TNT was removed from hotbar.
    • Removed Primed TNT, arrows, block drops and all mobs except Rana from the code.
    • Blocks no longer drop items when mined.
    • Attempting to fire arrows will not do anything.
    • No survival build of this version was released, so these changes go unused, and can only be found via modding.
  • Multiplayer was made partially inaccessible (although the multiplayer code still exists and can be re-enabled).
    • Connecting to a multiplayer server will cause players to spawn in a bedrock cube.
    • The game will act as if it is in Singleplayer – chat is inaccessible and the player list cannot be opened.
  • New W.I.P level format
    • Level saving/loading no longer works.
  • Dandelion (item) JE1.pngFlowers in the build screen are now shown with both sprites crossed[verify].


  • Generating new world in a huge size sometimes causes a lot of Ranas to spawn close to the player, resulting in the game freezing for some time.
