Solar Sphere: Expansions is an expansion for Solar Sphere released in 2022 for 1–5 players, 60–120 minutes per game, and ages 14 and up. It was designed by Jonny Pac and its main mechanics are Set Collection, End Game Bonuses, and Solo / Solitaire Game.
The Solar Sphere Expansions box contains the White Dwarf and Corporation Robots modules, and additional components to support a fifth player. With the construction of Solar Sphere #1 underway, The Corporation has set its sights on a nearby White Dwarf. You can now choose to survey the White Dwarf to gain valuable resources and opportunities. The White Dwarf expansion adds a unique rondel mechanism, where you can chose to move a meeple up to the value of your die, or if you have upgraded the White Dwarf location, you can move two meeples for extra rewards! The Corporate Robots expansion adds a set of cards and meeples that act as remote access to worker locations. Install the cards into your command centre and deploy the meeple robots to locations to fully upgrade that location's power! You can then access that location from your command centre. A fifth player can also now join the table with all the components needed to do so. Are you ready to expand the Solar Sphere? —description from the publisher
Solar Sphere: Expansions supports 1–5 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: Expansions 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 Solar Sphere: Expansions for ages 14 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: Expansions has a complexity rating of 3.0 out of 5 from BoardGameGeek players, which makes it a medium-weight game.
