What is Quantum Chess?
In this chess variant, you split pieces between two squares, merge them, and plan around captures that resolve uncertain positions. Entangled pieces have linked outcomes, and winning means capturing the king in every possible outcome rather than achieving checkmate. You can play online or share a device for local matches.
For you if...
- +you enjoy adapting chess strategies to probability and uncertainty
- +you want to explore quantum concepts through board game rules
Not for you if...
- −you want traditional chess without probability affecting captures

Does Quantum Chess use AI-generated content?
Yes. The developers disclose AI-generated content on the game's Steam page:
Handmade most of the art in game, before the current gen AI wave. That said, AI is an incredibly powerful tool for rapid prototyping and iteration. AI was used to help concept art for achievements and store capsules, and generic UI. Code agents, not image gen tools, were instructed to write svg code to produce a specific image composition, which was then refined by hand. AI was also used to help with the design and text in the "Learn" section, but again it was refined by hand.
The statement mentions: ArtText & translationsCodeStore page & marketing
Self-reported by the developer under Steam rules: it covers AI content that ships in the game, not tools used to make it. Steam page checked on Oct 28, 2026. How to filter AI games on Steam
