Dinosaur Game: June 2009 LSAT, PrepTest 57 Section 1

If you're looking for free interactive explanations to LSAT logic games, you've come to the right place.

This game is from PrepTest 57, which was administered in June 2009. The pencast form is pretty good for showing how a 180 LSAT test-taker attacks the logic games section and has 15 minutes to spare.

Questions 12-17 are infamous, often collectively characterized as (at least one of) the hardest LSAT logic games ever. Hopefully everyone will recognize where this picture is from, but the video below will help if you can't figure out what the topic of the game is.

If you said the game was about "color," specifically mauve, you win!
Okay, so it's actually the "color" of "dinosaurs," and they're only toys for a display and not nearly as scary as those in Jurassic Park. But a tyrannosaurus rex does appear, as well as a tricky velociraptor.

The actors are assigned subgroups (colors) and then either selected in or out. The assignment and selection affects which other actors can be assigned and selected, creating a recursive logical nightmare for anyone not using a matrix diagram to sort it all out.

This game is obviously a hybrid of just about every non-sequencing rule that the LSAT can throw at you. The Zen system of setting up one diagram to display all the interactions and doing the must/cannot be questions first, however, can make sure you not only survive the encounter, but that you can do so with five minutes to spare.
