Sidewalkia is one of the 200 Word RPG Challenge finalists for 2018. It's a game about expanding the nation of Sidewalkia, and the final line says:
The game ends if your population reaches 15 or you have expanded to three or more squares of concrete.
Ending at 15 population is straightforward enough. However I'm not sure how we ever satisfy having three or more squares of concrete.
I can see we start out with our first square. Then if I understand correctly we expand to a second square if/when we have more than 4 people as a one-time event:
If your total numbers reach more than 4, expand to another square and redistribute your population how you see fit.
But how do I, as a proud national of Sidewalkia, grow our nation to that third square? Unless I'm missing something, there doesn't seem to be anything in the game that gets us to that state.
