PenguinChess

PenguinChess is a free, no-registration-required chess training platform designed to help players of all levels improve their game.

🎯 OPENINGS Train your opening repertoire with interactive drills. Choose from multiple openings (Danish Gambit, Vienna Gambit, Scotch, Caro-Kann, Sicilian Dragon and more), select your difficulty level (Main, General, Expert), and get instant feedback on every move. The app prioritizes lines you struggle with most, so you always train where it matters.

?? TACTICS Solve over 50,000 puzzles sourced from the Lichess open database. Filter by theme (fork, pin, skewer, discovered attack, mate in 1/2/3...) and difficulty rating. Challenge yourself with Streak mode — how many puzzles can you solve in a row? A competitive mode with a live Elo rating tracks your tactical progress over time.

? ENDGAMES Learn essential endgame techniques (Queen + King, Rook + King, Bishop + Knight mate...) through guided theoretical training. Then test your skills in Practical mode against Stockfish at adjustable strength (800 to 2000 Elo).

🔍 ANALYSIS Analyze any position with Stockfish 16. Navigate through move history, draw arrows, visualize the evaluation bar, and explore variations freely in sandbox mode.

📊 PROGRESS TRACKING Create a free account to save your stats across devices: opening mastery (exponential moving average), tactical Elo rating with progression graph, endgame win/draw/loss records, and personal streak records.
