Place all tiles in two stacks. Place the beginning tile with a meeple in the middle of the table. Working evenly from both stacks complete the 8 tiles around the beginning tile. All features must match up just like the regular game. If you can't use a tile set it to the side. After the 8 tiles are placed place meeples on those 8 tiles and complete the next ring(16 tiles) by the same rules setting aside unusable tiles. The meeples are just place markers so you know what ring you are working on. After both stacks of tiles are used count the unusable tiles and that is your final score.
The best I have done with the base set and and expansion 1 and 5 is 32.
