Every puzzle comes from the Lichess open puzzle database — millions of real positions taken from actual games, each rated by difficulty and tagged by theme (fork, pin, skewer, sacrifice, checkmate, and more). Solve as many as you like; there is no daily cap and puzzles never repeat in a session.
They’re pulled live from Lichess’s open, community-verified puzzle database, which draws positions from real games played on the site.
No. Puzzles load on demand with no cap, and you can filter by theme to focus on a specific tactic you’re working on.
Yes. When you analyze a game on the Analyze page, any tactical positions found in it are made available here as puzzles from that game.
