Every puzzle on ChessScreenshot is free, with no account and no sign up — the daily run and the unlimited Practice pool are both drawn from the same large, curated library of chess puzzles.

Positions come from the official Lichess open puzzle database, filtered for clear, well-rated tactics, so every puzzle has one correct idea rather than an ambiguous 'best move.'

The chess puzzle of the day is one fixed sequence, shared by everyone who plays that day, with 3 lives and a timer that starts on your first move. Get a puzzle right and the opponent's reply plays automatically; get it wrong and you lose a life but can try the same puzzle again — the solution is never revealed while your run is live.

Difficulty rises as the run goes on, and because everyone gets the same ordered set of chess tactics puzzles that day, your result is directly comparable to a friend's.

Once your daily run ends — or any time you want extra reps — Practice mode serves unlimited chess puzzles from the same curated pool, with no timer pressure and no effect on your daily result.

It's the fastest way to see more tactics: no waiting for tomorrow, no limit on how many you solve in a sitting.

Tactics puzzles train pattern recognition: forks, pins, skewers, discovered attacks, and back-rank ideas that recur constantly in real games. The more patterns you've seen and solved, the faster you spot them at the board — including when your opponent is setting one up against you.

Regular tactics practice also sharpens calculation — reading out a forcing sequence accurately before playing it — which is often the single biggest jump in strength for improving players, more than opening memorization or general strategy.
