little giveaways with puzzle

I made 2 giveaways.

1. 7 days to die
2. Gremlins, Inc.

to get to the games you have to solve my questions here and then find the 2 keys to open the gate. after that you have to pass the magical wall who lets only characters through with the following skills:

Minimum ratio using Real Value of gifts Sent/Won on Steamgifts: 1
Your account must have activated all the won gifts
Your account is not allowed to have won the same game multiple times.
Your account must never been VAC banned.
Custom rule: trade_ban == false and community_ban == false and level >= 5 and num_owned_games < 1000

tips to solve the cipher are given after solving the questions.

Good luck!
