Uncover hidden words by lamplight. Lamplit is an acrostic puzzle game: a modern take on the Victorian tradition of weaving secret messages into clever clues. Solve each clue, and watch the first letters of your answers reveal a hidden spine word, glowing to life one letter at a time. A DAILY PUZZLE, EVERY DAY, FREE Monday to Friday brings a single acrostic. Weekends bring the double acrostic, where the first and last letters of your answers spell two hidden words. Holidays bring puzzles of their own. RACE THE CLOCK, OR KEEP THE VIGIL Every daily ranks on Daily Solve Time, and the timer only runs while you're solving, so stepping away never costs you. Keep your streak alive and it goes on The Long Vigil, alongside everyone else who solved today's puzzle. A STARTER LIBRARY, NOT A DEMO Twenty puzzles from day one, free forever, to play at your own pace. TWO CLUE STYLES Modern clues are clean and direct. Classic clues are lyrical and cryptic, in the Victorian parlour tradition. Earn Classic Mode by playing: it's a reward, not a paywall. ON IPHONE, IPAD AND IPHONE DUO On iPad and the unfolded iPhone Duo, the spine word runs down its own column beside your clues, so you watch the hidden word appear as you type. Play in portrait or landscape, in Split View or a Stage Manager window. Your progress, streak, hints and shields sync through iCloud, so every device shares one streak.
