Chessperiment (chessperiment.app) is a web platform dedicated to creating highly customizable chess variants. Unlike conventional chess websites, Chessperiment allows users to design their own unique games — with full control over boards, pieces, rules, and interactions.
Key Features
Everything you need to redefine chess
Custom Boards
Create boards in any shape and size that match your vision.
Advanced Piece Editor
Design pieces with unique movements and abilities.
Visual Scripting
Use drag-and-drop for triggers, effects, and variables — similar to Scratch — to create complex game mechanics without programming.
User-Created Variants
Experiment and play your own chess variants or try out the creations of others.
Our Mission
Chessperiment exists to push the boundaries of creativity in chess. We want to give everyone, from beginners to advanced players, the ability to invent, share, and play entirely new chess experiences.
Chessperiment is developed by a solo developer who is active on Reddit and GitHub. Launched just a few weeks ago, the platform has already attracted over 100 users exploring the endless possibilities of customizable chess.
