Guillotine is a fun, quick, bloodthirsty little card game that would grace any group's collection. It is very simple, which is just as well, as the rulebook errs on the side of vagueness.
There is one card, though, where it's hard to work out how the creators envisaged it to be played. The Master Spy goes to the back of the line after any action card is played.
There are two ways of interpreting this. Either the action card is fully resolved, and then the Master Spy goes to the back of the line. This means that, basically, the Master Spy cannot be executed except fortuitously, when he is the only person left standing at the end of a day.
The other interpretation is that the action card is played, the Master Spy goes to the back of the line, and then the action card is resolved. So, supposing you play an action that reverses the line: the Master Spy goes to the back of the line, then the line is reversed, and then THWACK! It's off with his head.
The latter way of playing appeals to most of the groups I've been part of, simply because it allows for clever play (or at least as clever as you can get in a game like Guillotine). I do suspect us of approaching the game too much like diehard Magic: the Gathering rules lawyers: drawing a fine temporal distinction between a card's being played and a card resolving is probably not something that would occur to casual card players.
I was wondering, if anyone else here has ever played Guillotine, how do you play the Master Spy? (I can't imagine Guillotine is a serious enough game for there to have been an "official ruling", but if there has, that would constitute an even better answer!)
