Mestre da Gramática

The Portuguese Language Tower has its seven rooms locked — Word Classes, Spelling, Accentuation, Punctuation, Agreement, the Crase rule, and Verbs — each one guarded by a puzzle that only someone who truly masters the language can solve. Without the right keys, not a single sentence in the tower makes sense. You've been recruited as the new linguistics apprentice to open room after room, phase after phase, proving you have mastered every rule of the Portuguese language. Every phase cleared without mistakes leaves the tower a little brighter — and you a little closer to becoming the Grammar Master.

Grammar Master is organized into 7 themed categories: Word Classes, Spelling, Accentuation, Punctuation, Agreement, the Crase rule (correct, required, and forbidden uses) and Verbs. Each category is split into progressive phases of multiple-choice questions. Answer correctly to advance through the phase — a wrong answer breaks your streak but doesn't end the game. Completing a phase with zero mistakes earns the "Perfect Phase" bonus. Correct answers add up to XP, which raises your overall level, and the game has its own achievement system, like "Spelling Master" (15 correct spelling answers), "Comma King" (10 correct punctuation answers) and "No Mistakes" (3 perfect phases).

The biggest challenge lies in rules with exceptions inside exceptions — like the crase rule before place names, or the difference between the Portuguese "mal" and "mau" (both roughly "bad/badly," but grammatically different), which changes depending on whether the word sits near a verb or a noun. Spelling and Accentuation require memorizing cases that break from the general rule. Keeping a phase perfect (with no mistakes at all) gets harder in the Agreement and Punctuation categories, where longer sentences hide details that are easy to miss on a quick read.
