Guess Watt Challenges Players to Build Electrical Grids Without Cutting Power to Communities

September 30, 2026

REN – Redes Energéticas Nacionais has launched Guess Watt, a game that challenges participants to plan and build electric grids, ensuring energy supply to different communities and responding to events that can put the infrastructure under pressure, as disclosed in a press release.

According to the same source, the game aims to simulate some of the decisions involved in the planning and development of grids. In each level, players have a limited budget and must decide how to deliver energy, sourced from different sources, to the communities.

Among the decisions are choosing the sites where to build, investing in repairing the networks, and responding to changes in energy production that could compromise supply. The game also introduces unexpected events, such as storms and accidents, forcing players to adapt their strategy.

The sustainability component is integrated into the decisions throughout the game, which seeks to raise awareness of some of the factors involved in the development of electricity transmission networks.

“O Guess Watt allows participants to experience the various steps of the network development process and to understand how sustainability must be present in all strategic decisions,” explains Margarida Ferreirinha, Director of Sustainability and Communications at REN.

According to the official, the game was designed especially for a young audience and addresses different stages associated with the construction and operation of grids, including stakeholder relations, easements, and environmental issues.

Recommended for ages 12 and up, Guess Watt was developed through a collaboration between WYgroup companies. The strategic and creative component was handled by WYcreative, the technical development was provided by WYnova and Bliss Applications, and the media campaign by WYperformance.

The game is available for mobile devices via the App Store and Google Play.
