The game you are playing
RoChess! is rated chess. Opening recognition, puzzles, and Game Review only make sense under ordinary chess laws. This page is the movement reference for that game. It is not a second ruleset invented for Roblox.
Both sides start with the usual army. White moves first. A move is legal only when your own king is not left in check.
How each piece moves
| Piece | Move | Capture |
|---|---|---|
| Pawn | One square forward, or two from its starting square, if the path is empty | One square diagonally forward |
| Knight | An L shape: two squares one way and one square perpendicular | The piece on the arrival square. Knights jump |
| Bishop | Any distance on one diagonal | The first enemy piece on that diagonal |
| Rook | Any distance on a rank or file | The first enemy piece on that line |
| Queen | Any distance on a rank, file, or diagonal | Same as a rook or bishop |
| King | One square in any direction | An adjacent enemy piece, if the square is safe |
You cannot pass through your own pieces. Except for the knight, you cannot jump.
Special moves
Castling. If the interface offers it, select the king and then the highlighted square toward the rook. It is legal only when the king and that rook have not moved, the squares between them are empty, the king is not in check, and the king does not cross or land on an attacked square. Kingside and queenside are separate choices.
En passant. If an enemy pawn moves two squares and lands beside your pawn, you may capture it as if it had moved one square. The option exists only on the immediate next move. If you play something else, it is gone.
Promotion. A pawn that reaches the last rank is replaced. Queen is the usual choice. The other pieces are legal too. Choose from the prompt the game shows. Do not assume the pawn stays a pawn.
How games end
Check is an attack on the king. You must answer it by moving the king, capturing the checker, or blocking. Checkmate is check with no legal answer. That is the normal win.
A game can also end by resignation, by an agreed draw, or when a player's clock runs out under the selected time control. Stalemate is a draw: the side to move is not in check and has no legal move. Other standard draw cases include insufficient material, threefold repetition, and the fifty-move rule when the game enforces them. This wiki has not seen a separate RoChess! draw menu that replaces those laws.
Capturing more pieces does not by itself end the game. You still have to mate, or the opponent has to resign or flag.
Using the highlights
Published control notes for the current interface say you tap or click a piece and then a highlighted square. An unhighlighted square does nothing useful. When you are in check, only moves that escape check are offered. Castling, en passant, and promotion use that same select-and-place flow when they are legal.
Practice each special move once against an easy bot before you rely on it in a rated game.
