Hi Pouche,
Thanks for posting. We love hearing from our players.
What you are asking is a little bit difficult. Firstly, making a better bot for Lost Cities, although certainly feasible, is not something easy. It would take days if not weeks. Secondly, this is adding some complexity to the platform and at the moment, we are trying to avoid adding too many special cases.
I understand though that you want more challenges. Maybe our new solo games, that will come with a series of puzzles, will give you something to look at for a while.
