About Fuji Flip
Fuji Flip is a memory (pairs) card game for people learning languages. You flip two cards at a time to find matching pairs, and every card shows a picture and a word and speaks the word aloud, so you pick up vocabulary while you play; holding the right mouse button shows the translation. The store page lists more than eight Japanese decks, including hiragana, katakana and dakuten, and more than five decks each in Spanish and French (animals, fantasy, clothes, fruit and vegetables, numbers and more), with new decks promised in free updates. You can play alone with no timer, with two players taking turns on one computer, or against the computer on easy, medium or hard, fully offline. The developer says they learned French by playing and listening rather than drilling grammar, and made the game to learn hiragana the same way. On the store page the developer writes that the code is written by Claude, which they direct and play-test change by change; the card art starts in PixelLab and is edited by hand, the voices and sounds are made with ElevenLabs and checked by ear, and the translated text is also written with Claude. Nothing is generated during play. A free demo has been on Steam for Windows and Linux since 29 Oct 2026; the full game is planned for 30 Nov 2026, with the interface in English, French and Latin American Spanish.

How it was built
Partially verifiedThe developer's store description says: “The code is written by Claude, which I direct and play-test change by change. I've spent many hours guiding, checking and editing all of it to make a game I believe in and am proud of.” The Steam AI disclosure adds that the code and the translated text are written with Claude, an AI assistant, under the developer's direction. No model or app is named.
- DeveloperThe demo's own Steam AI disclosure repeats that the code and the translated text are written with Claude under the developer's direction. — Steam
Per the developer, Claude writes the code and the translated text, and the developer directs and play-tests each change. The card art starts in PixelLab, an AI pixel-art tool, and is edited by hand; the card voices and sound effects are made with ElevenLabs and checked by ear. All content is made in advance and the game runs fully offline. The Steam requirements list a Vulkan 1.0 graphics card; the engine is not stated.

“The code is written by Claude, which I direct and play-test change by change.”Verification notes: The AI claim rests on two developer-written texts on the game's Steam page (read on 4 Nov 2026): the “How Fuji Flip is made” section of the store description, which says the code is written by Claude, and the AI disclosure, which says the code and translated text are written with Claude; the demo's page carries the same disclosure. The developer calls Claude an AI assistant and names no app, so the tool is recorded as Claude. Decks, modes and the developer's reasons come from the store description. Planned release date, platforms (Windows and Linux) and languages (English, French and Latin American Spanish, all with full audio) from the Steam store API, and the demo's release date from the demo app (5476670). The store page showed no user reviews on 4 Nov 2026. No website is listed; team size and location are not stated.
