Turn every light off.

Made for a few minutes a day.

  1. One puzzle a day

    Everyone gets the same board, gentle on Monday and tougher by Sunday. Par is the fewest moves it can take, so a perfect day is always possible.

    The day’s puzzle in Unlit: a five-by-five board with nine lights on, four moves in, par 7.

  2. Streaks and stats

    Solve each day to grow your streak. Stats show how often you hit par, your moves over par and your last 14 days.

    Unlit’s Statistics screen: 12 puzzles solved, a 7-day streak, a 58% Perfect rate and a chart of moves over par.

  3. Practice

    Finished today’s puzzle? Play practice boards for as long as you like. They never touch your streak or your stats.

    A practice board in Unlit, labelled: Doesn’t count toward your streak.
