Caps Lock

Every word has been knocked to lowercase — your job is to put the capitals back exactly where they belong.

How to play

You get a run of five sentences with all capitalization stripped out. Tap each word that should start with a capital — the first word of a sentence, names, places, days, brands — then check your answer.

• Tap a word to capitalize it; tap again to undo
• Leave ordinary words lowercase — over-capitalizing costs you
• Hit Check to score the sentence, then move to the next one
• Earn a Perfect when every capital is right and nothing is over-capped

Controls

• Desktop: click a word to toggle its capital, or focus it and press Enter/Space; click Check and Next
• Phone & tablet: tap words and buttons directly

Game modes

• Daily: a seeded set everyone shares that day, with a global ranking
• Practice: a fresh random set every round to drill the rules

Tips & strategy

• Always cap the first word, but watch for mid-sentence proper nouns that hide in plain sight
• Common nouns like seasons, school subjects and directions usually stay lowercase — a frequent trap
• Speed adds a small bonus, so commit once you spot every name
