There's no need for DB, go into multiplayer put in your Slitherine/Matrix name and password. You'll get a automatic 'key' most likely starting with 'WITE -' you'll then see a list of challenges, there you will see my one. Russian player moves first.
I'll take a look but was thinking something along of the lines of 12 turns or less. Yes, I have all the expansions so I have quite a choice of small, medium or large scenarios to pick from. Do you have a scenario in mind?
