Hi, I'm hakairyuousinn (my X account).

I made Soft Serve Challenge (ソフトクリームチャレンジ), a game about piling soft serve as high as you can on a cone.Play Soft Serve Challenge for free.
It runs right in your browser, on a phone or PC.

Soft Serve Challenge cover: a cone piled high with soft serve, standing on a wooden counter
The cover art. The tagline says “Swirl it higher.”

How to play

  1. Press the screen and cream starts coming out of the machine above.
  2. Keep pressing and move your finger, or mouse on PC, to move the cone. Make circles to build up the swirl.
  3. When you think it's about to fall, let go. That's your finished cone.

Height is measured from the rim of the cone to the top of the cream. The rim is 5 cm across.
You get a title based on height: “Kids' Size,” “Regular,” “Large”… The highest is “To the Sky” at 100 cm.

If it collapses or spills outside the cone, it doesn't count as a record.

You can also use the keyboard on PC. Hold Space and move with WASD.
You can save your finished soft serve as an image or post it on X.

Stay still and it falls in 3 seconds

If you keep dispensing without moving your finger, the cream grows into a thin column and soon snaps.

Three Soft Serve Challenge screenshots: a thin column bending over, a collapse at 6.0 cm and a Large result at 16.9 cm
From left: dispensing without moving until it bends, “Collapsed…” at 6.0 cm, and a 16.9 cm “Large” made by circling

When I tested it with an automated AI player, all five attempts without movement fell over after about 3.3 seconds.

Circling and gradually making the circles smaller gets it to about 20–24 cm without collapsing. Faster circles got it to 34 cm.
When I took the screenshots for this entry, slow circles got me 16.9 cm. A Large.

At first, it didn't look like soft serve

AI built the game. The first version was ready after lunch, and it took about three hours from there to release.
In the first version, the cream had a flat, plank-like cross-section. It didn't look like soft serve. It also collapsed too soon even when I was circling properly, so I made several fixes.

At first the nozzle moved. I changed that so the machine stays still and you move the cone.
After a few goes, 50 cm was already reachable, so I added more titles up to “To the Sky” at 100 cm. Can anyone actually reach 100 cm…?
