Step 0 — Create an account (about 1 minute)

Open play-game-yard.com/upload/ and register. No email address is required — just two fields:

Label on screen	Meaning
ハンドル	Handle (username)Letters and numbers.
パスワード	Password

The form — 4 sections, top to bottom

Section heading (Japanese)	What it is / what to do
① ゲームの zip を選ぶ	Choose your game zip.Pick a card first: 「ブラウザで遊べる」= browser-playable (index.html at the zip root) / 「ダウンロード配布」= downloadable / 「外部ストアへのリンク」= link to an external store (Steam, itch.io). Then drop your zip. The title is auto-filled from the file name. Upload the zip first — the malware scan runs while you fill in the rest.
② 作品の紹介	About your game.Two choices: 「自分で書く」= write it yourself, or 「シドラスタジオにお任せ」= leave the copy to us (we write your description; you can replace it later). If you pick the second, you only choose a genre — nothing to write.
③ 画像とこまかい設定	Images and details — all optional.You can skip this section entirely and still publish.
④ 確認して投稿	Review and submit.Tick the consent checkbox (rights stay yours; the license is non-exclusive and you can take the game down yourself at any time), then press 「投稿する」= Submit.

What happens after you submit

Your zip goes through an 8-step malware scan (usually a few minutes). If it passes, the game goes live immediately and you get the URL. The scan record — engine version, scan date, SHA-256 — is published on your game's page, so players can verify what they download. If the scan flags something for review, we check it by hand before publishing.
