Welcome to Game of Kings Online Chess, where you can play chess online with other Scratchers, or watch an ongoing game! At start you might have to wait 45 seconds until a seat is available. You have 45 seconds to make your move, otherwise another player might take over (check player names). Scratcher level is required to play online ( https://en.scratch-wiki.info/wiki/Scratcher - due to cloud variables). After program start you are placed onto a player slot if available, otherwise you can watch the ongoing game in the meantime. Click the "Join" button to take a slot. Once you got a playing slot and it's your turn (your name will show a visual marker), click the piece to move, then click the field to move to. You have 45 seconds for each move, otherwise the slot can be obtained by someone else. As a spectator, you can watch the ongoing game. Either human vs. human, or human vs. the GoK engine, or GoK engine vs. the GoK engine. GoK steps in if there is no other player around. FAQs: - "Why invalid move?" Quite likely it puts you in check. Please go sure you know the chess rules. - "Castling doesn't work!" It does, see castling rules. - "I found a bug!" Please describe in detail: board setup, user input, what happened. - "Opponent pawn captured my pawn which had already passed it!" That's called 'en-passant'. - "How to castle?" Move the king two squares; none of the passed squares must be in check, and neither king nor rook must have been moved before. - "How to play en-passant?" Move your pawn diagonally by one square, behind the opponent pawn which just moved two squares.
