Upcoming practice sessions!

We are planning on organizing open practice sessions for anyone to learn the game and get better at it. Once we have enough people ready for it, we will organize a tournament with real prizes :). Stay tunned... (You can add yourself to the email list and get timely updates.)

About GCG

Gemini is distributing a card game with unique designs and challenging gameplay.
The Gemini Card Game is a cooperative game for 2 to 4 players who work together to complete science programs over the course of 2 week turns for a semester. Experience the complex decisions required to run a world class observatory and the excitement of contributing to a team as you provide researchers with their precious data and contribute to expanding the knowledge of the Universe.

GCG played in person

You prefer to play with physical cards rather than online? No problems, this section is for you!

If you do not know the rules yet, download the rule book! This is version 1.0 (2019 May 30) and only for games played with physical cards.
Please, read and use this manual. It looks better printed in booklet form! If anything is unclear, or inconsistent, or for any suggestion, please email achene@gemini.edu.

If you have an official card deck...

Please register your deck. You will get (non frequent, we swear) updates of the rules, and alerts when expansion sets and booster packs are available!

Errata and rule changes!

Please, concider these changes for the 2019 Basic Deck:

1. Mistake in the scenario card.

Unfortunately, the scenario card was printed with the '2 or 4 player" scenario on both sides... The 3 players scenario should be like this:

2. Extra card in 3 players mode

It is now recommended to add one card in everyone's hand when playing with 3 players. A full hand is therefore 6 cards, unless someone's ability already allows for more cards, in which case it is the number of card for a full hand plus 1 (e.g., 6+1=7).

3. Moving Altair to an instrument does not require action

Altair can now be moved to a 'compatible' instrument (i.e., NIRI, GNIRS or NIFS) without requiring an action from a player. Still, if the instrument is moved to another program, Altair has to be discarded and placed at the bottom of the instrument deck.

If you do NOT have a deck yet...

Download a full deck to print at home!!! Here are the instructions to create a full 90 card basic deck:

  • Print one of each of the Instrument cards.
  • Print one of each of the Target cards.
  • Print one of each of the Time cards.
  • Print one of each of the Program cards. Make the Checkouts and the Poor Weather cards the two sides of a same card.
  • For the Weather cards,
    • print 2 "Best" weather cards,
    • print 1 "Great" weather card with a red border,
    • print 4 "Great" weather cards (no red border),
    • print 4 "Good" weather cards,
    • print 4 "Poor" weather cards,
    • print 1 Earthquake card, 1 Storm card, 1 Shutdown GN card and 1 Shutdown GS card.
  • Print one of each of the Role cards. Make :
    • the 1st and the 2nd cards the two sides of a same card,
    • the 3rd and the 4th cards the two sides of a same card,
    • the 5th and the 6th cards the two sides of a same card, and
    • the 7th and the 8th cards the two sides of a same card
  • Optionally, you can print the Reference+Rules cards.

One trick is to print them on paper, cut them, and place them into playcard sleeves. To obtain the right dimensions, you can print 6 cards per US letter size paper in using the portrait orientation. In Acrobat, you can select the option "Multiple" under Page size & Handeling. If available, choose the option "fit to printable area". Use transparent card sleeves to make the double sided cards. Use (or make) different backs for the different decks. Those are the Instruments, Weather and Player (Time, Target and Programs) decks (see the video).

Enjoy!


Short video tutorial

How does it compare to reality?

Of course, it is just a game. At best, it is a simplistic model of the decision making in place when the Gemini staff is scheduling and observing programs. Also, if 12 rounds is a semester, it means that each round is 2 weeks, and one should expect much more telescope time to be used in real life.

However, Band 1 programs take absolute priority, as they were estimated by peers to be the best use of the telescope time. Band 2 programs are preferable when there are no possibility to observe Band 1 programs. And Band 3 programs are essentially fillers, so good science may be possible when the weather is bad, or when nothing else is available.

Also, deciding on which target to observe, is not always straightforward. Observing a setting target instead of a higher priority one, with the hope to catch that other target later is sometimes the best strategy.
