3D Chess Free Online – Play the Computer, a Friend or a Daily Puzzle
A real 3D chess board in your browser. Pick one of five computer levels, play a friend on the same phone, or solve a short puzzle every day. No download, no account, no cost.
What you can do here
- Play the computer on 5 levels. Level 1 is gentle and makes mistakes. Level 5 thinks deep and does not forgive a loose piece.
- Play a friend on one device. With Auto-flip on, the board turns to whoever has to move.
- Solve puzzles. Every puzzle is a "mate in 1": one move wins the game. A new daily puzzle shows up each day.
- Get help when you are stuck. The Hint button shows a good move. The coach box tells you how the piece you picked moves.
- See who is ahead. The thin bar on the left grows white when White is better and dark when Black is better.
- Turn, zoom and tilt the board any way you like, and switch between a wood, marble or neon board.

Chess rules in 2 minutes
♙ Pawn
Moves one square forward. From its first square it may move two. It captures one square diagonally forward. When it reaches the last row, it turns into a Queen, Rook, Bishop or Knight.
♘ Knight
Jumps in an "L": two squares one way, then one square to the side. It is the only piece that can jump over others.
♗ Bishop
Moves any distance diagonally. Each bishop stays on one colour for the whole game.
♖ Rook
Moves any distance straight: up, down, left or right.
♕ Queen
The strongest piece. She moves like a rook and a bishop together.
♔ King
Moves one square in any direction. He must never stay in check. If he is in check and cannot escape, that is checkmate and the game is over.
Three special moves
- Castling: the king moves two squares toward a rook, and the rook jumps over him. Only if neither has moved, no pieces are between them, and the king is not in check or passing through check. In this game, tap the king and you will see the castling square as a green dot.
- En passant: if a pawn moves two squares and lands next to your pawn, you can take it as if it had moved one square. Only right away, on the next move.
- Promotion: a pawn on the last row becomes a new piece. A window pops up so you can choose.
A game is a draw when the side to move has no legal move but is not in check (stalemate), when the same position appears three times, when neither side has enough pieces left to mate, or after 50 moves each without a capture or pawn move.
About the daily puzzles
Each puzzle is a real position from a game. One move gives checkmate, and only one. Look at every check first: checks are the moves the king must answer. If your move does not mate, the board resets and you can try again. The daily puzzle changes every day at midnight, so it is a nice 2-minute habit with your morning coffee.
7 tips to win more games
- Control the centre. Start with a pawn to e4 or d4. Pieces in the middle reach more squares.
- Bring out knights and bishops early. Do not move the same piece again and again in the opening.
- Castle in the first 10 moves. A king in the middle is easy to attack.
- Before every move, ask: what does my opponent threaten? Most games between beginners are lost by a piece that was simply left hanging.
- Look at checks, captures and threats – in that order – when you search for your own move.
- Count the value. Pawn 1, knight 3, bishop 3, rook 5, queen 9. Do not swap a rook for a knight unless you win something else.
- Do not rush the queen out. She gets chased around and you lose time.
Is chess good for your brain?
Chess asks you to hold a plan in your head, picture moves that have not happened yet and remember patterns you have seen before. That is why many schools use it. Studies with school children have linked regular chess lessons to better concentration and maths results. Research on older adults suggests that mentally active hobbies like chess, reading or puzzles go along with sharper thinking in old age.
Be fair about it, though: chess is a training for the mind, not a medicine. The real benefits are simple ones – 15 calm minutes away from endless scrolling, practice in patience, and learning to live with a loss and try again.
What this game cannot do
- It is not an online game. Two players must share one device.
- The computer is a practice partner, not a top engine like the ones used by grandmasters. Its "who is better" bar is a quick guess, not a deep analysis.
- There is no chess clock and no rating.
- Your stats live in your browser only. A different phone or a cleared browser starts at zero.
- On very old phones, levels 4 and 5 can take a few seconds to answer.
