And you won't find such information on this forum.

As said above, it's a ban-able offence to tell anyone how to HEX or duplicate on Junk Jack X. In PM's or not.
All that we are gonna say here, is that you can. Junk Jack was completely different to Junk Jack X, there was no multiplayer.
AND with all the people on gamecenter throwing stuff out to newbies, it's ruining their game experience. You don't join a minecraft server and instantly have a full set of God Armour and a base created for you, so why should it be any different in this game?
