The game is of Arcade type and consists of a set of mini-games that allow the player to go through different stages of the urban water cycle in cities (households, sewers, a wastewater treatment plant, and a river), except for the drinking water collection and treatment stages. The game is for primary school students from 10 to 12 years old. At each stage, different challenges are posed to the player that help him/her identify and acquire knowledge, and at the same time allow researchers to introduce concepts about recent scientific advancements. The connections between the mini-games allow us to see the interconnections between different elements of the urban water cycle and to establish the link between activities in cities that generate changes in the quality of the water, their effects on the environment (river) and how research helps the sustainable development of cities. The game has narrators who give instructions to the players; the narrators are inspired by real researchers in the water field.
