GigaWatt is a board game released in 2022 for 1–6 players, 60–120 minutes per game, and ages 12 and up. It was designed by Milo van Holsteijn and Wouter Vink and its main mechanics are Variable Player Powers, Player Elimination, and Trading.
Europe, end of 20th century. Our economy runs entirely on fossil gas and coal-fired power plants. Climate change is a fact. Which region will have sustainable (non-fossil) electricity production first and wins the game? Each game round, the electricity demand (in GW) in your region increases due to the fate of the Dice. It's up to you to build power stations to produce the required GW demand. This provides you with income, with which you can eventually close the old fossil power stations and replace them with sustainable power stations that do not emit CO2. You can trade GW surpluses and GW shortages with the other players or External Markets to balance supply and demand. So are you going to increase sustainability quickly (with the risk of GW shortages), or are you more careful (at the risk of being late)? The region that is the first to produce more GW than the GW demand and has closed all its fossil power plants, wins. But beware, wind and solar energy sometimes only generate half of their GW power peak. —description from the designer
GigaWatt supports 1–6 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for GigaWatt is 60–120 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists GigaWatt for ages 12 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
GigaWatt has a complexity rating of 2.6 out of 5 from BoardGameGeek players, which makes it a medium-light game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
