At the top of the red village that you start the game in you will find 2 red people staring at 5 small white towers with screens on them. You will know you are in the right place if the 2 red people are saying "Amazing game, so much better than its predecessor" and "Perfect, 5/7!".
In front of the screens is a red button that says 9. Press this 9 times and the achievement is yours
