The new merger will be about all presidents of the USA. Starting with George Washington and ending with Joseph Biden. A player should merge two similar presidents to get a new president.
The upgrade system is three buttons. A player can upgrade:
- Speed of generating a new president.
- President's level. Which level will have a president when he appears. In other words - which president will be appearing next.
- Income coefficient.
After we upgrade the president's level, all presidents below the current level will transform to current level presidents (if they exist on the grid).
