Chess
Checkmate your opponent’s king β here, against a bot you can dial from gentle beginner up to genuinely uncomfortable, or against a friend on the same screen.
How to Play Chess
Chess is played on an 8Γ8 board with sixteen pieces a side, each moving its own way: rooks in straight lines, bishops on diagonals, the queen doing both, knights in an L-shaped hop, pawns forward and capturing diagonally. White moves first, and the goal is checkmate β attacking the king so that no legal move saves it. Every rule is in: castling, en passant, promotion to the piece of your choice, and all the ways a game can end in a draw β stalemate, threefold repetition, the fifty-move rule and insufficient material. Add a clock if you want one: 3, 5, 10 or 15 minutes, with 0, 2 or 5 seconds added per move.
Play Chess Against the Computer
Pick one of ten bot levels, from “just learning” to “maximum”, and play as White, Black or a random color. The two lowest levels play the way real beginners do β they overlook recaptures and leave pieces hanging β so a first win comes early, and each level above resists a little harder. From level 3 up, the computer resigns a hopeless position instead of making you play it out. If the bot is still too strong, hand yourself odds: either side can start without a queen, a rook, or both rooks. On levels 1 to 5 you can take back up to three moves a game.
Play Chess With a Friend
Choose Two Players and the game runs on one device: one of you takes White, the other Black, and you pass the phone or share the screen. Flip the board when it helps, set a clock for a proper blitz game, and use up to three take-backs if you are playing to learn rather than to win. This is chess for two people in the same room; there is no online matchmaking here.
A Brief History of Chess
Chess begins with chaturanga in 6th-century India, travels into Persia and the Arab world, and reaches Europe from there. The rules we play today β the fast, long-range queen and bishop β emerged in Europe at the end of the 15th century and were universal by the end of the 19th. Wilhelm Steinitz claimed the first recognized world title in 1886, and in 1997 Deep Blue beat the reigning champion Garry Kasparov in a match β the first computer to do so.
Benefits of Playing Chess
A bot you can configure is the most efficient way to improve, because you set the resistance exactly where learning happens: strong enough to punish your mistakes, weak enough that you sometimes win. And every game is reviewable β step back through the move list to the moment it went wrong, and the lesson is usually one move you can name. Download the game as a PGN file and you can open it in any chess program; captured pieces collect beside the board with the material balance, and an unfinished game stays saved in your browser until you start a new one.
Tips and Principles for Winning at Chess
In the opening, get your pieces out and your king safe instead of chasing early captures: develop knights and bishops toward the center, castle, connect your rooks β a piece in the middle attacks more squares. Before every move, ask what your opponent’s last move threatened β most losses below master level are missed threats, not bad plans. Trade when you are ahead in material, avoid it when you are behind. And in the endgame, when the queens are gone, bring your king to the center: it stops being a target and becomes one of your strongest pieces.

Chess vs. Go: Two Ways to Win a Board
Chess is a game of material and a single target: pieces have fixed values and everything ends when one king cannot escape. Go keeps the capture mechanic but changes the goal β stones are identical, none of them move once played, and you win by surrounding more of the board. The calculation skill carries over completely, which is why chess players get hooked fast. We compared the two in detail in Chess vs Go; if you would rather just try it, start with Atari Go, a capture-only version you can play against a bot within minutes, and then learn the rules of Go.
