A game with similar vibes that works really well over conference call is Keep Talking and Nobody Explodes. Even better, only one person need own a copy of the game for others to play with them.
For anybody who's unfamiliar, the game is thus: one person is stuck in a room with a bomb. They can pick the bomb up, manipulate it, and interact with it, but a clock is ticking and the bomb is going to explode. On the phone with you are the Bomb Defusing Experts, who are armed with a Bomb Defusing Manual for the bomb in question (free PDF, www.bombmanual.com if you're curious). Unfortunately, the manual was written by somebody who loves inscrutable graphs and hates the person reading it.
The person with the bomb has to describe the modules on the bomb, e.g. "I see three red wires, a blue wire, and a white wire". The people with the manual then need to instruct them on which wires to cut in order to defuse the bomb correctly, e.g. "Three red wires? Cut the second wire. Wait, hang on - does the bomb have a parallel port? Okay, cut the third wi-WAIT, how many batteries does it have? Did you cut the third wire? thank god, definitely don't cut that one."
The bombs can get hard and stressful, but it's a fun asymmetric game that works really well over voice chat.
