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.
