While playing Catan – Rise of the Inkas, you have to decline the early tribes twice so you can make way for the era of a new tribe. You get rid of all the constructed roads on the board and use vines to cover the settlement to signify that these are no longer up for development. However, it isn’t the end of the game. Once your tribe declines, you can put a new settlement on the available space on the board and continue with the game with the new settlement.
How can you win in this game
The declined settlements of your tribe cannot be developed into cities anymore and you also cannot create roads from these. The tribes of your opponents can even replace them. But, provided that they stay on the board, the cities and settlements of your previous culture will continue giving you resources. The game ends once your third tribe is established. You win if you are the first one to completely develop the tribe and lead the rise of Inkan Empire.
