Fischer Random Chess — also known as Chess960. Same rules, 960 starting positions and no memorized openings. Play now against the AI.
About the game
Chess960 — also known as Fischer Random Chess — is a chess variant in which the eight pieces on the back rank (rooks, knights, bishops, queen and king) start shuffled. The order is randomized, but it's the same for both players, and everything else — pawns, piece movement, check, checkmate and draws — is identical to standard chess.
The name comes from the 960 possible starting positions. Since you never know which one will appear, it's impossible to memorize opening lines: the game forces you to think for yourself from the very first move. That was exactly the intention of world champion Bobby Fischer, who introduced the variant in 1996.
On BoardGame Battles you play Chess960 for free, right in your browser or in the app, with no account needed. Just open chess and switch on Chess960 in the toggle at the top of the board.
See the difference
In classic chess the back rank is always the same. In Chess960 it's randomized. Compare a standard setup with an example Chess960 position — notice that only the order of the back-rank pieces changes; the pawns and everything else stay the same:
Fun fact: the classic setup isn't excluded from the 960 — it's position number 518 in the official Chess960 numbering. In other words, standard chess is just one of the nine hundred and sixty possibilities.
How it works
If you already know chess, you already know Chess960 — there's only one difference. The starting position of the back rank is randomized following two rules that keep the game fair and playable:
Black mirrors White's setup. Beyond that: White moves first, pawns advance and capture as always, there's promotion, there's en passant, and the goal is still checkmate.
Side by side
| Aspect | Classic chess | Chess960 |
|---|---|---|
| Starting position | Always the same | Randomized among 960 |
| Opening theory | Decades of theory to memorize | None — you think from move 1 |
| Piece movement | Standard | Identical |
| Castling | King moves 2 squares | King taps its own rook; ends on the g/c file |
| Check, mate and draw | Standard | Identical |
| Who starts ahead | Whoever studied more openings | Everyone on equal footing |
Special move
Castling is the part that confuses beginners most, because in Chess960 the king and rooks start on variable files. The rule, however, is simple and leads to the same final result as standard chess:
Because the king sometimes moves only one square — or doesn't move at all — on BoardGame Battles you castle by tapping the king and then your own rook. It's the worldwide Chess960 convention (the same as on Chess.com and Lichess): there's never any ambiguity about which castling you want.
Why play
In top-level classic chess, the first 10 to 20 moves have often already been studied and memorized at home. Chess960 erases that edge: with 960 possible positions, there's no opening theory to memorize. Everyone — from beginner to master — is on equal footing from move 1.
That rewards the purest side of chess: understanding the position, coordinating your pieces and calculating. Many players say Chess960 made them see the board better, because it forces you to reason instead of repeating memorized lines.
Strategy
History
Chess960 was created by Bobby Fischer, the legendary American world champion, and unveiled publicly in Buenos Aires in 1996. Fischer was troubled by how much elite chess relied on memorized openings and proposed shuffling the back rank to hand creativity back to the board.
Over time the variant earned official tournaments and became a fixture on Chess.com and Lichess. In 2019, FIDE ran the first official Fischer Random World Championship, won by Wesley So; the 2022 edition went to Hikaru Nakamura. Big names like Magnus Carlsen are declared fans of the variant.

Frequently asked questions
What is Chess960?
It's a chess variant where the 8 back-rank pieces start shuffled — the same order for both players. There are 960 possible starting positions and every other rule is the same as standard chess.
Is Chess960 the same as Fischer Random?
Yes. Chess960, Fischer Random Chess and Chess 960 are the same game, created by world champion Bobby Fischer in 1996.
How does castling work in Chess960?
You castle by tapping the king and then your own rook. The king always ends on the g file (kingside) or c file (queenside), with the rook beside it — just like standard chess.
How many starting positions does Chess960 have?
Exactly 960. The positions follow two rules: bishops on opposite-colored squares and the king always between the two rooks, so castling stays possible.
Is Chess960 harder than normal chess?
It's not harder, it's different. With no openings to memorize, everyone starts on equal footing — from beginner to master.
Is standard chess one of the 960 positions?
Yes. The classic setup is position number 518 in Chess960 numbering — one of the 960.
Can I play Chess960 for free?
Yes. On BoardGame Battles it's free, against the AI on three levels, in your browser or app, no sign-up. Switch on Chess960 at the top of the chess screen.
What's the difference from normal chess?
Only the starting position of the back rank, which is randomized. Everything else is the same. The effect is killing memorized opening theory.
