Welcome to Callisto!
In Three Days on Callisto you control a small team of pioneers on the heavily cratered moon of Jupiter. Your job is to expand out from the base in the Valhalla crater and develop new craters, improve your technology, and ultimately produce goods to make the citizens of Valhalla more comfortable. and
Build Your Engine
Building farms enables you to hire more workers to your team.
Building robotics labs will help your workers move to new craters and build new structures.
Building logistics centers allow your workers to accomplish more tasks each day.
Improve your diplomatic relationship with the Ganymedeans and enjoy greater assistance.
Keep Your Clients Happy
The main way to score victory points in the game is to supply your clients in Valhalla City with the things they miss most while living on a remote moon of Jupiter.
When your colonist enters a new crater he collects one of the salvage parts shown at the top of the crater. You may then store this salvage on your player mat by placing a clear cube or Valhalla token on the appropriate space. Collecting sets of these salvage parts pay off in the form of resources or victory points.
Send colonists to craters where they can extract elements needed in Valhalla. Building up your element purifier will increase your compensation in the form of additional victory points.
During a given round only one of Callisto's hemispheres can harvest solar energy, leaving the other half largely dormant. In the following round daylight shifts to the hemisphere. You must decide carefully how many colonists to send to the productive hemisphere; some of them may end up stranded there at nightfall.
