It's a critical-thinking game for ages 8 to 18. Students learn to separate a conclusion from its supporting evidence, and to identify the logical fallacies that keep an argument from holding up.
What partners get
Mind Merit is a critical-thinking game, not a full curriculum. Students build two connected skills: identifying the components of an argument, and evaluating why an argument is flawed.

Every argument makes a claim and offers evidence for it. This track trains students to pull the two apart, what's being claimed and what's supposedly backing it up.

Not all reasoning holds up. This track trains students to spot where an argument breaks down, across 24 named logical fallacies, even when the conclusion sounds convincing.


Master both, and a student can take apart any argument, their own, a friend's, or an AI's.
Built for ages 8 to 18 (grades 3 to 12), with difficulty that adapts to each student.
Two meta-analyses spanning hundreds of studies reach the same conclusion: students don't absorb critical thinking on their own, it has to be taught on purpose, and it improves most when they practice on real arguments rather than memorizing rules. Mind Merit is built on that approach.

The reasoning Mind Merit teaches matters anywhere. For US educators and parents, here's exactly how it maps, to one continuous thread of the Common Core, Reading: Informational Text, Standard 8, which runs from grade 3 to grade 12 and asks students to trace, evaluate, and test the soundness of reasoning.
Every student plays both tracks from day one — difficulty adapts to the individual, not the grade.
In grades 3 to 5, Standard 8 is about learning to identify argument structure: explaining how an author uses reasons and evidence to support particular points in a text.
