Mojang has now unveiled another minigame that's coming in the latest update – ‘Tumble'.
This writer isn't a Minecraft veteran, but has been informed (and looked up the Wiki) that this is basically an official version of Spleef. In any case, it could be a popular addition.
As for when this'll arrive on Wii U, coincidentally there's maintenance coming up very soon, so the update could roll out after that; times for that server maintenance are below.
From August 30/31st, 6:50pm Pacific / 9:50pm Eastern / 2:50am UK / 3:50am CET – Tuesday, August 30/31st, 8:30pm Pacific / 11:30pm Eastern / 4:30am UK / 5:30am CET.
In other words, the update could roll around on Wii U late tonight into tomorrow.
How many of you hope to try out this minigame?
