About this app

A premium chess room with a physically based 3D Staunton set, richly textured 2D boards, adjustable computer levels, timed games, human invite rooms and a local chess-engine arena.

Requirements

WebGL2 for the 3D room, with a playable 2D fallback. Workers and WebAssembly for Stockfish and compatible imported engines. Online rooms and account saves require Hackemist sign-in. Imported browser UCI JavaScript and optional matching WASM run on the player's device; native executables and threaded distributions are unsupported.

Credits

Powered by Poly Haven assets, bundled locally. 2D Staunton renders: clarkerubber (MIT). Manrope, Instrument Serif and Noto Sans Symbols 2 (SIL OFL). Three.js (MIT), chess.js (BSD-2-Clause), Stockfish.js 19.0.1 / Stockfish 19 Lite (GPLv3). Complete notices and corresponding game source are bundled.

Release notes

Version 2.0.1: rotate directly from any part of the 3D board, including square controls. Spread or pinch two fingers to zoom; visible − / fit / + buttons and keyboard + / − / 0 provide alternatives. Drags and multi-touch gestures cannot become accidental moves. Camera orientation and zoom survive resizing, and zoom joins personal preferences. The renderer releases its GPU resources when leaving the game. Includes the rebuilt responsive room, sculpted PBR Staunton set, 16 finishes and three realistic 2D collections from version 2.0. Five computer levels, local/online human play, Blitz/Rapid/Classical clocks and device-run UCI engine matches retained. Startup prepares shaders asynchronously, static scenes stop requesting frames, unchanged clock labels avoid DOM rewrites, and Balanced detail adapts shadow resolution on software graphics.

3D Staunton board during local human play — A real local two-player opening with sculpted Staunton pieces and physical surface lighting.

Carrara finish and desktop Appearance collection — Carrara is selected from the 16 available board finishes.

Textured 2D board on a phone — The same legal position with rendered wood pieces in the phone board layout.

Classical timed-game setup on a phone — Human game settings with Classical selected. Starting a new game applies the chosen clock.

Finish library in the narrow phone layout — Appearance uses a dedicated screen and a contained scroll region at 320 pixels wide.

Move journal on a portrait tablet — The move journal shows the four opening plies played in this recording.

Local engine match setup on desktop — Engine Arena configuration with two built-in engine choices and local browser UCI import controls. The match is not running in this capture.

A real checkmate result on a tablet — A real local Fool's Mate, completed by legal moves in the recording, shown in the result dialog on a tablet.

Actual desktop 2D application footage: a local human opening, Carrara finish, Classical clock setup, Appearance and Moves tools, Engine Arena configuration, and a new local game ending in a genuine four-ply checkmate. The gallery separately shows the 3D room and phone/tablet layouts. The clip does not demonstrate live engine-vs-engine play, online peers or cloud saves.
