Solar Sphere is a board game released in 2022 for 1–4 players, 60–90 minutes per game, and ages 10 and up. It was designed by Ayden Lowther and Simon Milburn and its main mechanics are Set Collection, Dice Rolling, and Area Majority / Influence.
The human race has exhausted all the energy available on planet Earth. If they are to advance into an intergalactic civilisation they must harness the power of a solar system. They must build a dyson sphere. Solar Sphere is a dice placement/manipulation game with elements of engine building, resource management, and set collection. Set hundreds of years in the future in a time when competition will move mankind forward, but when collaboration is also sometimes necessary. In Solar Sphere, each player commands a mothership. Their primary task is to build a dyson sphere. But, with crew to hire and aliens attacking the sphere, there are many other ways to earn prestige and become the saviour of mankind. In this dice placement game, players can manipulate their dice using drones. However, players have a limited supply of drones, which are also used to upgrade dice placement spots or to support in fights against aliens. Players can always recycle used drones to get them back into their supply. Or, spend them for instant benefits. Players simultaneously start the turn by rolling their dice. Dice act as spacecraft and are sent, in player order, to locations to gather resources, build the dyson sphere, build or recycle drones, upgrade worker spots, hire crew, and fight off aliens. Crew come with their own unique benefits that will help players in a variety of areas. Chain crew abilities together to build a good engine, and retire them for extra benefits. Making space for new crew members. As the game progresses, more aliens will arrive to defend a sun that they also need. Fight them off alone, or join forces with other players and share the rewards. However, if no one takes on the rebellious aliens, then you all lose points. Solar Sphere combines a combination of mechanisms with a powerful theme to bring players an immersive experience. —description from the designer
Solar Sphere supports 1–4 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 Solar Sphere is 60–90 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 Solar Sphere for ages 10 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.
Solar Sphere has a complexity rating of 2.7 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.
