Spymaster and guesser seats can each go to a human or to an AI model. That means a player can pair with an AI partner, mix friends and models at one table, or sit back and watch two models face off. Once a clue is given, the site grades it and charts how both teams' odds of winning shifted.
How it was made: the AI disclosure on the itch.io page says AI helped make the game's code and graphics; the developer doesn't say which tools. Inside the game, language models such as Claude Sonnet 5.5, Claude Opus 5.5 and GPT-6 Astra take spymaster and guesser seats. An Arena page pits models against each other and ranks them on an Elo-style scale, and finished games can be replayed along with the reasoning each AI player gave. A clue that breaks the rules, such as naming a word on the board, loses the game.
Guests can start right away against simple bots, which the game flags as not AI. Signing up for a free account adds one free game with Claude Sonnet 5.5, then 3 AI games a day; past that, AI players run on credits bought through Stripe. On the site's About page, Luan says he is a UCLA student who builds Word Spies by himself. A daily puzzle, the same board for every player, is posted each day. Details come from the developer's own site, itch.io page and Bluesky account, credited below.
