Chess Royale – A Complete HTML5 Chess Game for the Browser

Chess Royale brings the classic strategy game to any website as a fast, ready-to-play HTML5 experience. Built with HTML5, CSS3 and vanilla JavaScript, it needs no backend or database, so you can publish it on a game portal, learning site, portfolio or kids’ website with minimal setup.

Play Against a Smart AI Opponent

Challenge a computer opponent powered by a minimax engine with alpha-beta pruning. Choose from three difficulty levels – Rookie, Challenger and Master – and set time controls to suit your style, including no time limit or 10- and 15-minute games. You can play as White or Black, flip the board, and track your progress with a local Elo-style rating that saves between sessions.

Full Chess Rules, Polished Presentation

The game supports the complete rule set, including check, checkmate, castling, en passant, pawn promotion, stalemate and draws. Moves are shown with smooth animations, legal-move highlights and optional board coordinates, while sound effects and separate music tracks for the menu, gameplay, victory and defeat add atmosphere without distracting from the board.

Helpful Features for Every Player

• Three hints per game to help you find a strong move
• Undo a move, including the AI reply, to try a different plan
• Draw offers that the AI evaluates and accepts or declines
• Promotion, game-over, settings and confirmation modals
• Animated loading screen, main menu and player cards with timers

Responsive, Lightweight and Easy to Customise

Chess Royale is fully responsive and touch-friendly, so it plays comfortably on phones, tablets and desktops. The code is organised into separate modules for the game, AI, music and app flow, and the included documentation explains setup and customisation. Swap piece images and icons, adjust colours through CSS variables, tune AI strength, and rebrand the title and logo to match your own site.

Whether you want to add a timeless, skill-based game to your platform, teach chess in an interactive way, or showcase a polished coding project, Chess Royale delivers a complete, engaging chess experience that visitors can open and play straight away.
