About ひとり玉
A free shogi-themed puzzle game for the browser. You have one piece, the king (玉), and your goal is to capture all the shogi pieces on the board with it. You click or tap the square you want the king to move to, or pick it with the arrow keys and confirm with Space, Enter or Z. The developer describes it as a move-by-move game of reading ahead with little luck involved; a play takes a few minutes and you can start again straight away. The game page says it plays in PC and smartphone browsers and is made for portrait screens. The credits in the ReadMe say the art, sound and program were made using generative AI (Claude Code), with the pictures and sounds drawn and synthesised by the program rather than taken from image or audio files. The game page gives the development period as four days.
How it was built
Partially verifiedThe ReadMe credits list the art, sound and program as made using generative AI (Claude Code), and say the pictures and sounds are drawn and synthesised by the program rather than taken from image or audio files. The game page lists HTML5 / JavaScript and Claude Code (generative AI) as its production tools. Neither page describes how the developer worked with Claude Code.

An HTML5 / JavaScript browser game. Per the ReadMe, the art, sound and program were made using Claude Code, and the art and sound are generated by the program, so the game ships no image or audio files. The game page gives a development period of four days. No devlog describes the process.

Verification notes: AI use from the developer's own credits in the ReadMe on Freem! (“絵・音・プログラム 生成AI（Claude Code）を使って作成しました。”) and the production-tools line on the game page; no other source was found, and the Relia creator page links no website or social account. The credit does not give a share of AI-written code, so none is recorded. Registered on Freem! on 14 Oct 2026 (version 1.00); Freem! files it under table games and Go / shogi games. The game page gives four days of development. Whether Relia is one person is not stated, so team size is not recorded. The ReadMe says the game saves only the best score and the sound setting on the device and does not communicate externally during play, so no AI runs while you play. The game was not run, so the puzzle rules are described only as far as the page explains them. Freem! shows no reviews yet.
