It's the new updated version (DC-1.0.0.51) that gives you Unlimited Food and Gems. I downloaded this when I had the previous version and it told me to update it so it brought me to the link. Then I tried it and it would give lots of food for 10 tries (for free). But as soon as I upgraded, it kept crashing.
Actually I went to his website and autogenerated a lot of Gems using the 2 gems feature. Normally I was limited to 10 but now I'm getting a lot. I have like over 400 gems right now.
Still, don't trust this hack. I'll be testing it with macroing the 2 gem hack.
EDIT: This hack bans you for 30 minutes if you keep pressing for gems even after waiting 5 seconds on the webpage.
Well the hack is updated so nevermind about this. It's not a scam. I'm already getting over 11m food! Sorry for my attitude.
