It was just me, Ness and Duncan last week. Both Duncan and Ness enjoy card games, so I pulled out Cosmic Eidex. I played this several months ago and got absolutely thumped but enjoyed it. This time was no different.
I clarified the player aid on the Geek, which helped a lot. I just uploaded it and it is waiting for administrator approval.
After this second playing, I suspect seating position might play a part in the outcome. I will swap sides next time to see if it makes a difference.
This is definitely my favourite three player card game. There is a lots to think about and it is very skilful.
I am tempted to come up with a simpler version, based around Whist, that you can play with a regular card deck and a reference sheet. I would aim for the game to be the equivalent of Gang of Four compared to Tichu.
