Play Chess with ChatGPT (OpenAI, GPT 3.5 or GPT 4) or GeminiPro (Google). There are two modes: (A) The standard mode, both you and the AI would follow the standard chess rule, so no illegal move! You can choose between: 1. The native ChatGPT4 API (weakest chess player); 2. Prompt improved GPT4 API (e.g. better chess player); 3. Enhanced backend chess calculation API call with GPT4 (i.e. strongest chess player). (B) The No-Rule chess mode.  In this mode, we strictly follow the instruction provided by ChatGPT AI to make the move. Enjoy a chaotic and hilarious chess game. Don't be surprise if AI makes illegal moves, captures its own piece, generates random pieces, and suicides. :) You can choose different LLM AI: 1. GPT 3.5 (OpenAI); 2. GPT 4 (OpenAI); 3. Gemini Pro from Google. A minimalist design, just start to play, that simple. Also, the ChatGPT will talk to you during the play! Come and see if you can beat the ChatGPT in chess!

About

Beyond Chess D20

Features
Read full description

Beyond Chess is a strategy game that takes the core of chess and adds one missing ingredient: uncertainty. Choose how you want to play: CLASSIC MODE Pure chess. Deterministic captures. No randomness. STATISTICAL MODE Captures are resolved by probability. Each piece has a fixed chance to capture other pieces, sometimes you win, sometimes you bounce back. No victory is guaranteed. RPG DICE MODE (D20) Every capture attempt rolls a d20: • 1: Critical fail — your piece self-destructs • 2–5: Capture fails — your piece stays in its original square • 6–19: Normal capture • 20: Wololo conversion — the target piece turns to your color while your piece stays in place ONLINE PvP Play online matches in public or private rooms, choose a nickname and jump in. (Online play requires an internet connection.) If you enjoy chess, tabletop RNG, and tactical risk management, Beyond Chess is built for you.
