SL CHESS SYSTEM by NIKOTIN

Chess SL is a fully playable chess game built for Second Life by NikotiN. You can play Solo against yourself, challenge another player in Multiplayer mode, or play against the AI with three difficulty levels: Rookie (easy), Smart (medium), and Genius (master). Everything runs directly on an interactive board rezzed in-world. All moves, rules, promotions, castling, and en passant are handled automatically.

Every new player starts at 1200 ELO. After each multiplayer game, ratings are adjusted using the standard ELO formula with a K-factor of 32:

Expected = 1 / (1 + 10^((opponent - you) / 400))
New ELO = Old ELO + 32 * (result - expected)

Where result is 1 for a win, 0 for a loss, and 0.5 for a draw. Beating a higher-rated player earns you more points, while losing to a lower-rated player costs more.

Only Multiplayer games between two human players are ranked. Solo games (playing against yourself) do not affect your ELO or appear on the leaderboard.

A game can end in several ways:
• Checkmate — a player's king is trapped with no legal escape.
• Timeout — a player runs out of time on the chess clock.
• Draw by agreement — both players agree to end the game as a draw via the controller.
• Stalemate — a player has no legal moves but is not in check.
• Insufficient material — neither side has enough pieces to deliver checkmate (e.g. King vs King).

Click the Reset button on the controller to open the game options:
• Draw — proposes a draw to your opponent. They can accept or decline. If declined, you must wait 2 minutes before offering again.
• Resign — forfeits the game immediately. Your opponent wins and ELO is updated accordingly.

Streaks track consecutive wins or losses. A streak of 3W means 3 wins in a row. A streak of 2L means 2 losses in a row. A draw resets the streak to zero. Your best streak ever is also recorded in your profile.

Yes! Use the search bar at the top of the page. Enter the player's exact full avatar name (e.g. "Niko Rowley") or paste their Second Life UUID for a direct match. Names must be exact — partial matches are not supported.
