See If You Can Piece Together This SOTU LSAT Logic Game

Today is National Puzzle Day! So the LSAT blog is giving you the chance to celebrate in the true spirit of this nerdy day. That’s right: we’ve got an original LSAT Logic Game for you to piece together.

If you’re nursing a hangover from last night’s State of the Union drinking game (I did a shot every time Obama said “wage”), give yourself three bonus points. Here we go:

Both bill A and bill B will not pass
Bill B or else bill C will pass
If bill H passes, then bill G will not
Bill D needs to pass for bill E to pass
Bill H needs to pass for bill I to pass
If bill G doesn’t pass and bill F doesn’t pass, then bill E will pass

Hmmm, was there one in particular that tripped you up?

Hey Brandon,

Here are the keys to the game:

1. All the rules can be combined into a long conditional chain.
2. I is really important.
3. If both bills cannot pass together, that means at least one won’t pass. So, rule two really says: If bill C passes, bill D will not.
