Lazy Chess is a free, non-profit game created for casual players and enthusiasts alike, where players, at worst, make the second best move available to them. On average, there are more than 30 legal chess moves available to a player in a turn, creating vigintillions of possibilities throughout a game. Lazy Chess compresses that by having you choose only two in a given turn selected by Stockfish, the most robust chess engine in the world. The catch? You won’t know which move is the best! Learn and have fun while you compete against a highly skilled AI or online friends and random opponents. Unlock new themes and settings that can change how many options you choose from or the difficulty of the AI. Hone your chess skills while you move up in the leaderboards and play unique scenarios of famous board states provided from some of the world's most active grandmasters. Lazy Chess is open source and available on GitHub. It was developed by Cinq-Mars Media, an educational non-profit with projects and games featured at E3, PAX and festivals worldwide.

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!
