Frequently asked questions
How do you play LineBy?
Each puzzle is a famous quote scrambled into tiles. Drag any letter and drop it onto another to swap the two — a tile locks to blue the instant it lands in its correct cell. Restore the whole quote in as few moves as you can, then try to go lower.
How much does LineBy cost?
LineBy is free to download — a new puzzle every day, free forever. One optional in-app purchase, the Full Library unlock ($0.99, one-time), opens all 315 puzzles, the daily archive, and the custom puzzle builder — not a subscription. No ads, no tracking, ever — see how we keep our games fair.
Is LineBy the same as NYT's Letter Boxed or Letterboxd?
No. LineBy by 0n1 Studios — formerly called Letterbox — is a tile-swap quote puzzle for iPhone: a famous quote is scrambled into tiles, and you swap letters to restore it. The New York Times' Letter Boxed is a different game about linking letters around a square, and Letterboxd is a film review social network. Similar names, very different things.
How many puzzles are in LineBy?
315 hand-built puzzles: 106 historic quotes, 73 movie quotes, and 136 song titles, across four difficulty tiers — Easy, Medium, Hard, and Expert.
Does LineBy work offline?
Yes. The entire library works with no signal. iCloud quietly keeps your progress in sync across your devices when you are online.
Can I make my own puzzles?
Yes. Turn any phrase into a puzzle, set its difficulty, and sign it. Each custom puzzle gets a short code — share it and a friend can enter that code to fetch and play your puzzle.
What devices does LineBy run on?
LineBy is available for iPhone on the App Store. An Android version is coming soon.
