Praga Caput Regni is the latest game from Vladimir Suchy, the designer of Underwater Cities.

In this game, players take the role of wealthy citizens who are organizing various building projects in medieval Prague. By expanding their wealth and joining in the construction, they gain favor with the king. Players choose from six actions on the game board — the “action crane” — that are always available, but which are weighted with a constantly shifting array of costs and benefits. By using these actions, you can increase your resources, improve the strength of your chosen actions, and build “New Prague City”, the Charles Bridge, or city walls. You can possibly gain additional actions or even participate in the construction of St. Vitus Cathedral.

Clever players will discover synergies between carefully timed actions and the rewards from constructing civic projects as all of the mechanisms mesh together. At the end of the game, the player who most impressed King Charles wins.
