This is a game/world type. It is a superflat world made completely out of lucky blocks. In the middle there is a bedrock platform with villagers with trades to help you progress. You try to survive like normal minecraft. There are many ways of playing this, eg You could set a time limit and after that time you PvP with the stuff you have got or you can break blocks and try to live as long as possible.

to make it a challenge Natural Regeneration is off but depending on how you want to play it you may want to turn it back on.

It is made for 1.7.2, however 1.7.10  and 1.8 should work as well. YOU DO REQUIRE THE LUCKY BLOCK MOD AS WELL!

Let me know any questions, feeback or suggestions and I will try to respond ASAP!

Have fun and please give DIAMOND!
