 Star Fluxx

Fluxx gets the Science Fiction treatment. From the publisher: "Just when you thought that Fluxx had gone as far as it could go - it blasts off for the Stars! Explore the vastness of space-themed humor with your valiant Captain, Engineer, and, of course, your Expendable Crewman. Go check out that Small Moon – or is it really a Space Station? You may be swayed by Unseen Forces, held hostage by Evil Computers, or find your ship infested with Cute Fuzzy Aliens."

Zendo

Zendo is an inductive logic game in which the players compete to figure out a secret rule.

Zendo: Rules Expansion 1

Zendo: Rules Expansion #1 consists of ten new rule cards for use with the Zendo base game: one rated as Easy, four as Medium, and five as Difficult. These cards generate 45 different rules, but don't look through the new rules ahead of time as you want to figure them out for yourself as you play the game!
