CyberLite Chess 1.0

Start Here — Your First Game

The easiest way to begin

Choose New Game → Play CyberLite AI.
Select Move First, choose Easy, and use No Timer.
Drag one of your pieces, or tap it once. Legal destination squares light up.
Drop the piece on a highlighted square, or tap that square. CyberLite Chess will not allow an illegal move.
Keep playing. There is no need to memorize everything before your first game.

Good first goal: Move a center pawn, bring out a knight, bring out a bishop, and protect your king. Winning can come later—the first victory is simply feeling comfortable with the board.

How Every Piece Moves

Most pieces cannot jump over another piece. The knight is the one exception. You capture an opponent’s piece by moving onto its square.

KingMoves one square in any direction. Keep it safe—it may never move into check.

QueenMoves any number of open squares forward, backward, sideways, or diagonally.

RookMoves any number of open squares forward, backward, or sideways.

BishopMoves any number of open squares diagonally and always stays on the same square color.

KnightMoves in an L shape: two squares in one direction and then one sideways. It can jump over pieces.

PawnMoves forward one square, or two squares from its starting position if clear. It captures one square diagonally forward and never moves backward.

Which direction do pawns move?

Your pawns move away from your side of the board toward your opponent. Flip Board changes only your view; it does not change the real direction of play.

How to Castle in This Game

The one thing to remember: Move the king two squares toward the rook. Do not move the rook yourself—CyberLite Chess moves it automatically.

Desktop

Select or drag your king.
Move the king two squares toward the rook. The legal castling destination will light up when castling is available.
Release the king, or click the highlighted destination square. The rook moves automatically beside the king.

Phone or tablet

Tap your king.
Tap the highlighted castling destination two squares toward the rook.
The game moves both the king and rook into their castled positions.

The four castling moves

Black kingsideKing: e8 → g8

Black queensideKing: e8 → c8

Why is the castling square not highlighted?

Castling is legal only when the king and chosen rook have never moved, every square between them is empty, the king is not currently in check, and the king does not cross or land on a square attacked by an opponent. A rook may be under attack and castling can still be legal.

Easy memory rule: You cannot castle out of check, through check, or into check.

Check, Checkmate, Draws and Special Moves

Check and checkmate

Check means the king is under attack. You must immediately move the king, block the attack, or capture the attacking piece. Checkmate means there is no legal escape, so the game is over. The king is never actually captured.

Stalemate and other draws

Stalemate happens when a player is not in check but has no legal move. The game is a draw. CyberLite Chess also recognizes official draw conditions such as repetition, insufficient material, and the fifty-move rule.

Castling

Castling protects the king and activates a rook. Open Help → How to Castle in This Game for exact desktop and phone instructions, destination squares, and a checklist for when castling is legal.

Pawn promotion

When a pawn reaches the far end of the board, choose a queen, rook, bishop, or knight. A queen is common, but another piece can sometimes be smarter.

En passant

If an opposing pawn moves two squares from its starting position and lands beside your pawn, your pawn may capture it as though it moved only one square. This special capture is available only on the very next move.

Online Rooms, Invitations, Returning and Chat

Host a private game

Choose New Game → Online Private Room.
Select an available room, enter a four-digit PIN, choose your position and game appearance, then create the room.
Send the invitation with Text Invitation, Email Invitation, Copy Invitation, or your device’s sharing tools.
Your guest opens the link and joins using the same room and PIN.

Privacy and chat

The room is private to the players who have its invitation details. Chat stays with that room and opens directly below the board when you touch Messages.

Leave, close, and resume

A guest uses Leave Room. The host uses Close Room when the room should be released for everyone. Merely closing the browser does not instantly destroy the room; use Resume Online Room after an accidental close or connection interruption. A room with no player activity expires automatically after 30 minutes.

Move Timer, Pause, Time Loss and Rematches

The optional clock gives each player a fresh amount of time for every move. Choose No Timer or a per-move limit from one second through 60 minutes.

The active player’s clock counts down while that player is thinking.
The final ten seconds receive a visible and spoken warning when sound is on.
Reaching zero ends the game as a loss on time.
Offline timer changes and pause/resume actions happen immediately.
During an online game, timer changes, pause, and resume require both players to agree.
Online timing is synchronized with the room and safely restored after reconnecting.
A rematch keeps the agreed setup unless the players choose something different.

New player suggestion: Start with No Timer. Add a generous timer later when you want a little excitement—not pressure.

Themes, Music, Sound, Alerts and Comfortable Play

Make the board yours

Open Settings → Appearance and Colors to choose a ready-made 2D theme, create custom 2D board and piece colors, or use one of the premium 3D themes. In online play, the host saves the shared appearance so both players see the intended room design. It is restored after reconnecting and preserved for rematches.

Music, sound and alerts

Open Settings → Music and Volume for the eight-track instrumental playlist, Previous, Next, On/Off, and dependable volume controls. The selected track, volume, and music setting are saved only in this browser, so each online player controls their own music independently. Sound can announce important game moments, including the timer’s last ten seconds. Guest Arrival Alerts can notify a waiting host when the invited player arrives, subject to the browser’s permission.

Desktop and phone controls

On a desktop, drag pieces with the mouse or click a piece and then its destination. On a phone, drag with a finger or tap the piece and destination. The layout automatically rearranges so the board, chat, menus, and controls remain usable.

Easy Beginner Tips — Play With Confidence

Look at the whole board before moving. Ask, “Is one of my pieces under attack?”
Use the center. Center pawns and pieces have more room to move.
Bring out knights and bishops early. Try not to move the same piece again and again without a reason.
Castle when it is safe. This usually protects your king and activates a rook.
Do not rush the queen. A queen brought out too early can be chased around.
Before every move, check for captures, checks, and threats—for both players.
Losing a game is learning a game. Even experienced players miss moves. Enjoy the puzzle and play again.

Most important rule: Have fun. CyberLite Chess is here to make the game welcoming, not intimidating.
