Players roll a die to move towards Rome (26 spaces forward), when the last player crosses the river Rubicon (10 spaces from Rome) the round ends, and everybody in Rome shares the money in the pool.Players can make deals that either forces them not to move next turn, or that forces them to move next turn. Players that have not entered a deal have to move.Whenever a player crosses the Rubicon, they pick up a card that can affect movement (of their own and/or of opponent pieces), end the round prematurely, negate other cards that might be played, or nullify deals.The game does not mention if you can keep cards from round to round, and does not mention how many rounds a game lasts (or in fact how the game ends). - BoardGameGeek
