Flaw questions are the single most common question type in LSAT Logical Reasoning, and Parallel Flaw questions are notoriously time-wasting. Both reward one skill: recognizing an argument's structure. An argument about tea and an argument about sunburns look nothing alike until you see that both confuse correlation with causation. That structural pattern-matching is what Flaw Hunter trains.

How it works. Each fight deals you a hand of flawed arguments. Click one, then click another that commits the same flaw to land a hit on the monster. A wrong match costs Flaw Hunter a heart, and losing all three restarts the fight. Win the fight, and the flaws you spotted—correlation to causation, circular reasoning, ad hominem, part-to-whole, and more—are collected with plain-English definitions you can review anytime.

What you'll learn. Across seven fights, you'll encounter over 20 classic flaw patterns drawn from the ones the LSAT tests most. Because the game forces you to match flaws across wildly different topics, you learn to identify each pattern by its skeleton, not its subject matter—precisely the skill Flaw and Parallel Flaw questions reward.

When you want the full taxonomy with examples, the argument flaw cheat sheet below covers every pattern in the game.
