In Quadropolis, you and your friends become renowned architects, competing to build the most impressive metropolis. The game unfolds over four rounds, and in each, a central 5x5 board is filled with various types of buildings, such as shops, parks, public services, and factories. The trick here is how you choose your tiles: each player has four architects numbered 1 to 4. On your turn, you place an architect next to a row or column on the central board and take the tile that is in the position corresponding to your architect's number. For example, if you use architect number 3, you take the third tile from that row or column.

This chosen tile goes into your own city, a personal 4x4 board, in the row or column that matches the number of the architect used. When you take a tile, you also collect resources like inhabitants or energy, essential for activating your buildings at the end of the game. With each choice, the strategy becomes tighter, as the space from which you took the tile becomes blocked for the next player in that row or column, and you cannot use the same architect twice in the same round. After all architects have been used, the round ends, and new tiles are laid out. At the end of four rounds, it's time to tally points! Scoring depends on how you organized your city and activated your buildings with the correct resources. Residential buildings score by height, shops by customers, public services by distribution, parks by adjacency, harbors by longest rows, and factories by adjacent buildings. Whoever has the highest score earns the title of best urban planner!
