Back to the Mushroom Kingdom. Classic pixel-art side-scrolling platforming — collect coins, leap over pipes, reach the flag. Keyboard and touch supported.
Mushroom Arcade is a fan-made, pixel-art side-scrolling platformer in the style of the classic Mushroom Kingdom games. You run right, collect coins, hop over pipes and gaps, and reach the flag at the end of each level. It is an unofficial homage built by a hobbyist and published through ChatGPT Sites on 5 September 2026 — none of the characters or level design here are affiliated with or endorsed by Nintendo.
The whole thing runs in the browser with no download. It supports both keyboard and touch, so it plays the same on a laptop and on a phone held sideways.
How to play Super Mario · Mushroom Kingdom
- On desktop use the arrow keys or WASD to move and space (or the up key) to jump. Hold the run key to clear wider gaps.
- On touch devices the on-screen left/right and jump buttons appear at the bottom of the screen.
- Coins add to your score; reaching the flagpole finishes the level. Falling into a pit costs a life.
- Use the fullscreen button above the game for a bigger play area — it helps on smaller screens.
Controls: Keyboard and touch are both supported.
Click Fullscreen above the game for the largest play area. If the game does not load, use Open in new tab to play it directly from our copy.
Why it's worth your time
On a laptop it runs at full frame rate in any current browser; on a phone, hold the device sideways so the touch buttons do not cover the level. There is no save system — each visit starts from the first level, which is in keeping with the arcade games it imitates.
It is one of the newest games in this collection and one of the clearest examples of what a single prompt-driven build session can produce: a complete, playable platformer with working physics, tile collision, coins and a level end state, hosted on a plain static page.
The Play button runs our own copy of the author's page, so it keeps working if that address stops responding. It is a fan remake, and everything it borrows belongs to Nintendo; if the author or the rights holder wants it gone, the contact in the footer gets it removed the same day.
How it was made and where it lives
Published through ChatGPT Sites (chatgpt.site) — the same hosting pipeline GPT-6 Astra uses to ship playable games straight from a prompt. The author publishes as jumaomaomaoju. Original: https://mushroom-arcade-0905.jumaomaomaoju.chatgpt.site/. The Play button above runs our own unmodified copy, so the game keeps working here if that page goes down — which on free hosting usually has nothing to do with the author. Nothing about the game itself is changed, and the original stays linked from every page.
ChatGPT Sites is the hosting side of the workflow OpenAI describes for building games with GPT-6 Astra: the model writes the game, then publishes it to a public address in one step. That is why so many of the newest single-file browser games are appearing on chatgpt.site domains.
