Praga Caput Regni is the latest game from the genius of Vladimir Suchy, award-winning designer of Underwater Cities! During the game, players take the role of wealthy citizens who are competing to build various projects. Players choose from six actions on the game board using the "action crane." These actions are always available but linked to a constantly shifting array of costs and benefits. Players can increase their resources, improve the usefulness of specific options in the future, or build new projects in the city.

Savvy 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.
