What sequence of moves in Solo Caverna result in the maximum score?
The key to maximum points for my solo endeavours has been to use the Office which allows overhangs, and the Guest room for multiple actions.  I then work to get many tunnels inside, and overhang tunnels.  After the overhang tunnels are placed, I also place Ore mines, for even more overhang bonus, and use the double action to place two ruby mines at once.  For this to work, you need extra dwarfs, preferably 5.  You should be pulling in about 30ish gold.


All in all, because of the possibility of a 'optimal' strategy based on card layout, I also tend to use some dice to add some random blocking, so the game has some more replay-ability solo.

I usually score around 140.
