Logic Blitz

Judge whether an argument is valid. A game to practice conditional and quantifier logic.

About this game

Conditional logic and quantifiers aren't a side topic on the LSAT: they show up all over the Logical Reasoning section. Must Be True, Sufficient Assumption, and Parallel Reasoning questions all reward the ability to see instantly whether a conclusion follows from its premises. Logic Blitz drills that judgment until it's a reflex.

How it works. Each round shows you a short argument: premises, then a conclusion. Your job is to decide whether the conclusion must be true given the premises. You get three lives, and the clock ratchets up as you climb through levels. Every argument is generated from the same formal logic rules the LSAT uses, including the classic traps: affirming the consequent, denying the antecedent, and illicit moves with some, most, and all.

Make it yours. Want to isolate a weakness? Use the settings to practice only conditionals or only quantifiers, and choose a relaxed, standard, or untimed clock. After each run, you can review every question you saw—including the ones that got you—and your results map back to the matching lessons in the 7Sage curriculum.

If a question trips you up and you want the underlying theory, start with the conditionals cheat sheet or the conditional reasoning video below.
