Play CATAN? with 5 or 6 Players
You can settle CATAN with up to 6 players. If you want to play the CATAN base game with 5 or 6 players, just add the base game extension.
Please note: If, for example, you want to play the scenarios of the Seafarers expansion with 5 or 6 players, besides the Seafarers expansion you need one base game extension and one Seafarers extension. Similarly, this also applies to the other expansions.
