In Dorfromantik you can gain the perfect-status for a tile, if all six adjacent borders match perfectly to the neighbouring tile.

Woodland to woodland, grass to grass, village to village, water to water, railroad to railroad, field to field - you get the idea ...

Edit: Water, trainstation and grassland count as perfect when placed next to each other.

You get +60 points for a perfect and also one extra tile to your pile!
You get the points rewarded, when you close the last border of a tile. Beware: The perfect-tile is usually not the one you are just about to place, but rather the neighbouring tile, who gets its last open border completed.

An easy way to get perfect matches are field and woodland tiles. They are often mixed with only grassland. Just turn the tile respectively.

(I wrote this little guide because I was searching how to fulfill the "Perfectionist" achievement and had not found a detailed answer. Sometimes wondering why I got 60 perfect points at random situations I puzzled it out =)

See my example of a perfect-tile


Example, grassland mixed with water


And with a little planing and patience...
