World in a Jar is an old school map originally created for Minecraft on PC which now has been ported to Minecraft PE. Once you’ve loaded up the world you will find yourself locked up inside a glass jar. If it wasn’t because of the jar the world would be quite ordinary as you can find everything from dirt blocks to growing trees in the jar.

The challenge is to survive as good as you can and try to progress out in the remaining world to connect your jar with the other jars and take advantage of their resources such as animals and their different biomes.
