The Portuguese King has called the finest stonemasons of the country to pave one of the most important squares with calçada tiles (worldwide famous black and white tiles that pave several squares in Portugal). But the task is enormous and players will have to count with the aid of helper cards who will help them score points and/or collect money.

Rossio is a game with very simple rules, but with high interaction between players and interesting decisions every single turn.

- Very fluid and fast playing tile laying game
- Great table presence where players are actually filling a void with tiles
- Very easy to learn the rules for families, hard to master for gamers
- Climatic end of the game, as points increase exponentially in the last rounds
- Big replayability due to the bonus pieces of the square that are different every game
- Compelling Solo Mode where the player competes against an automated virtual opponent
