I had to wait over 20 hrs for a single build. Other option was to watch over 20 videos. It takes just as many hours to accumulate in-game credit to build. U are restricted to one build at a time. Each build is based on another. While waiting 21 hrs for a build I searched for another zombie game. In-game purchase does not require confirmation. If U accidentally select your gold bars to purchase something it's a done deal; no way to back out. I inadvertently used over 200 bars. https://webdaggers.blogspot.com
