The Mendery drills Standard English Conventions, the grammar questions in the SAT Reading and Writing section. Each round puts ten sentences on the anvil, one cracked slot apiece. You work as Flint, the smith: read the sentence, decide which of five rules the crack breaks, then choose the piece that makes it read correctly. The five rules are subject-verb agreement, pronouns, verb form, modifiers, and possessives, which cover most of what this question type tests.
A sentence appears on the anvil with one slot cracked open. Step one, name the flaw: choose which of the five rules the slot breaks. Step two, forge the mend: pick the option that makes the sentence read right. Naming the rule on the first try is worth the most, and a run of first-try answers builds a streak that raises your score. Miss the rule and you get one more look before the answer shows; either way you still forge the fix, because the correction is the lesson. After ten sentences, a ledger shows how you did on each rule.

Standard English Conventions, the grammar questions on the SAT Reading and Writing section. The Mendery focuses on five rules that account for most of those questions: subject-verb agreement, pronouns, verb form, modifiers, and possessives. You practice naming the rule and then applying it, which is the same work the test asks for.
You get one more attempt, worth fewer points. After that the game shows the piece that fits and a short note on why it works, and a wrong pick comes with its own explanation of why it does not. A miss still teaches the rule. When a set ends, you can start a fresh round from the ledger screen.
