Azul: Stained Glass of Sintra maintains some of the core tile drafting mechanisms of Azul, but introduces new tile laying techniques and a new theme. In Azul: Stained Glass of Sintra players are challenged to select colourful glass panes to adorn the windows of the chapel of the Palace of Sintra in Portugal.

Each turn, a number of market tiles will be filled with four random transparent plastic tiles, drawn at random and in a possible five different colours. On a player’s turn they will select to take all the tiles of one colour from a market location and add them to one column in their player board, representing a stained glass window. Tiles must be placed on a spot of a matching colour and any extra tiles will be wasted, resulting in a deduction of points.
