売り場を読む ── 地方スーパー経営

地方のスーパーが一軒閉まると、車のない年配の人は買い物に行けなくなります。北関東の国道沿いにある、そういう小さな居抜きのスーパーを任されました。

発注、値引きシール、パートさんのシフトと悩み、月末に一気に出ていくお金。Football Manager の管理画面のように数字と人を見ながら、ひと季節・90営業日を回します。売り場は3Dで、客の流れや棚の減り方がそのまま見えます。

何かが起きたら、原因ログで「なぜ」を一つずつさかのぼれます。同じ手を打っても、天気や暦で結果は揺れます。

最低賃金は毎年上がり、折込チラシが届く家は年々減り、パートさんは年末に扶養の壁で抜けます。全部、店の数字に入っています。それでも店を開け続けられるか。

• 無料版：開店の準備から90営業日の閉店まで。最後に通信簿が出ます。
• 新しく始めるたびに店の番号が変わり、同じ番号で遊び直せます。
• ブラウザで遊べます（Chrome・Safari の最新版、パソコン向け）。セーブはこのブラウザの中に残ります。ファイルにも書き出せます。
• 遊び方の記録（名前のない記録）は、最初に聞いて「送ってよい」の時だけ送ります。送らなくても全部遊べます。

生成AIについて：このゲームの文章（出来事、人の言葉、画面の説明、英語の文）は、生成AI（Anthropic の Claude）で書き、作者が選んで直しています。絵と3Dの形は CC0 の素材とプログラムで組み立てたもので、画像や音を作るAIは使っていません。

Reading the Floor — A Japanese Supermarket Manager

When a supermarket closes in rural Japan, older people without a car lose the place they buy food. You've been handed one of those stores: a small supermarket on a highway in rural northern Kanto, still fitted out the way the last owner left it.

Ordering, markdown stickers, part-timers' shifts and worries, and the bills that all land at month end. Run one season, 90 business days, from screens full of numbers and people, a bit like Football Manager. The sales floor is in 3D, so you can watch shoppers move and shelves empty.

When something happens, the Cause Log lets you walk back through why, one step at a time. The same move can turn out differently with the weather and the calendar.

The minimum wage goes up every year, fewer households get the flyer, and part-timers cut their hours in December to stay under their earnings limit. All of it is in the numbers. Can you keep the doors open anyway?

• Free edition: from opening prep to the close of business day 90, then your report card.
• Each new game gets its own store number, and you can play the same store again from that number.
• Plays in the browser (latest Chrome or Safari, on a computer). Saves stay in this browser, and you can also save to a file.
• A play record with no name on it is sent only if you say yes when asked at the start. Saying no changes nothing about what you can play.

About generative AI: The game's text (events, what people say, the screens' explanations, the English) was written with generative AI (Anthropic's Claude), then chosen and edited by its maker. The pictures and 3D shapes are built from CC0 assets and by code. No AI that makes images or sound was used.
