Chess: brass against steel, with whoever you want

About Chess

It is real chess with the official rules on the 8×8 board — only the pieces came out of Dália’s scrapyard: the pawn is a bolt with a hex nut, the rook is a stack of tires or drum sections, the knight is a bent monkey wrench, the bishop is a blowtorch nozzle, the queen wears a flame crown and the king a gear-wheel crown. You play the brass pieces against the steel ones. Against the machine there are four villains at four strengths: the Tamer plays any old way, the Driver looks a little ahead, the Jailer thinks four moves deep and the Executive six. With a friend it is one link: whoever opens it joins as your opponent and the match stays on the site — each of you plays whenever you can, with an on-screen notice when the other moved. Every chess rule is in: castling both ways, en passant, promotion with your choice of piece, check marked on the board, checkmate, stalemate and draws by repetition, 50 moves or insufficient material. No lives, no points: you win, lose or draw.

One of Selminha's ideas

“Chess is the most played board game in the world, and I wanted ours: pieces Dália welded from whatever was lying around the shop, the villains across the table and a link to call whoever you want — no sign-up, no app.”

How to play Chess

1. Tap your piece, then the destination square. Possible squares light up green; a piece you can capture gets a red ring. Tap the same piece again to let go. On a computer, click or use the arrow keys/WASD plus J or Enter; on a gamepad, the D-pad plus A or X.
2. Pick your character (Dália, Bruto Vale or Kiko Faísca). Against the machine, then pick your opponent — 1 Tamer (very easy), 2 Driver (easy), 3 Jailer (medium), 4 Executive (hard). You play the brass pieces and move first.
3. Playing with someone: tap PLAY WITH SOMEONE, type your name, then copy and send the link. Whoever opens it picks one of the two remaining characters, types a name and joins with the steel pieces. The match is saved: close it and come back any time through the same link. To continue on another device, use the personal link in the pause menu.
4. During a match with someone, the game tells you when the other player joined or moved (with the move notation); you can offer a draw, resign and, if your opponent goes more than two days without moving, end the match for absence. Rooms with no moves for 7 days expire. A full room can be watched — the game shows how many spectators there are.
5. When a pawn reaches the last rank, the promotion choice pops up: queen, rook, bishop or knight. A king in check gets a red square, and only moves that get the king out of check are allowed.
6. End of the match: checkmate wins. Draws: stalemate (the side to move is not in check and has no legal move), the same position three times, 50 moves with no capture or pawn move, or not enough material to checkmate. P or Esc pause; M toggles sound.

The pieces and how they move

Pawn (bolt)

Moves one square forward (two on its first move) and captures diagonally. On the last rank it becomes a queen, rook, bishop or knight — your pick.

Rook (tires or drums)

Moves in a straight line, across or up and down, as far as you like.

Knight (monkey wrench)

Moves in an L — two squares one way and one the other — and is the only piece that jumps over others.

Bishop (blowtorch)

Moves diagonally, as far as you like, always on the same color of square.

Queen (flame crown)

Moves like a rook and a bishop combined: straight or diagonal, as far as you like.

King (gear crown)

Moves one square in any direction and can never stay in check. Once a game, it castles with a rook.

Special rules

Castling

King and rook that have never moved, nothing between them, the king not in check and not passing through an attacked square: the king moves two squares and the rook hops to its side.

En passant

A pawn that just advanced two squares can be captured on the very next move by an enemy pawn beside it, as if it had moved only one.

Check and checkmate

An attacked king is in check (its square turns red); only moves that get the king out of check are allowed. No way out means checkmate — game over.

Draws

Stalemate (no move and no check), the same position three times, 50 moves with no capture or pawn move, insufficient material, or a draw by agreement.

Controls on phone and computer

Computer

Tap or click the piece and the square · arrows or WASD move the cursor, J or Enter select · P or Esc pause · M sound · F full screen · gamepad supported: D-pad moves the cursor, A or X select, Start pauses, Back toggles sound.

Touch

Phone upright and in full screen. Tap the piece and the square; resign and draw buttons below the board; the promotion choice shows over the board. Invite with COPY: paste the link wherever you like (WhatsApp, text…).

Against the machine and by invite

Four villains

Tamer (very easy), Driver (easy), Jailer (medium), Executive (hard): the machine looks 1, 2, 4 and 6 moves ahead.

Invite

One link per match. Whoever opens it joins as your opponent; the room lives on the site and each of you plays when you can. A personal link (in the pause menu) carries your seat to another device. Up to 10 open games per device — past that, the game lists yours and you close one with a tap.

Notices

Joined, moved (with the move notation), offered a draw, resigned — on screen, with sound and vibration; with the tab in the background the title blinks and, if you allow it, a notification goes out.

Watching

Room full? You can watch. Everyone sees how many spectators there are.

Rematch

Match over? You both stay at the table, with the result on screen and the question "Another game with NAME?". Both say yes and a new one starts in the same room, as many times as you like — anyone watching keeps watching.

No points

You win, lose or draw. The scoreboard shows the pieces each side captured and the material advantage.

There is no ranking in this game: between invited friends it would make no sense.
