Free LSAT Logic Game: Grouping: Splitting

LSAT Unplugged subscriber Caleb wrote this LSAT Logic Game.

I’ve modified the game’s questions slightly, but Caleb provided the core. All complaints and/or compliments about the game’s topic and rules should be directed to him 🙂

However, please thank him in the comments for allowing me to share the game with all of you!

I categorize the game as Grouping: Splitting since it divides the variables into two groups, both of which are present. Some similar LSAC-written Logic Games are listed at the bottom of this post.

Please post your thoughts and questions in the comments!
