Shake de Cafe au Lait: How to Split the Cup and Fill the Book

A mixed cup and a dare you can actually play

I made an ascetic game where all you do is shake. Using a straw is allowed too.

su10, the maker behind 100億ダーツ, framed the whole joke on November 4, 2026: shake cafe au lait and somehow get coffee and milk back. The official page puts the same dare in one line: shake the cafe au lait and split it into coffee and milk. Can you?

The playable build is the cup itself. You are not managing a cafe, a timer, or a customer line. The drink starts mixed, the screen counts how many times you shake it, and the only victory banner that matters is Perfect separation!

Shake the cup, sip it, or surrender

Tap or drag to shake. Every shake adds to the on-screen count, which can climb into units of ten thousand. Sip is the other legal move: the straw is a real button, not a joke in the blurb. Give up opens a white-flag check that asks if you truly quit, and you can still choose to keep shaking.

When the cup finally splits, the banner reads Perfect separation! From there you share the result or shake again, and a separate control puts the cup back to ordinary mixed cafe au lait. Sharing offers an image, a video built from a single shake, or plain text.

• Shake

  Tap or drag the cup. The counter records the shakes.

• Sip

  Use the straw as the alternate way to work on the drink.

• Give up

  The white-flag prompt lets you quit or go back to shaking.

• After the clear

  Share, shake again, or return the cup to its normal mixed state.

Eight slots, a ninth complete screen, and a gold cup

The ending book opens at 0/8. Slot No. 1 is Perfect separation! Other fragments you can read include The orthodox way, Black, no sugar, and Spilled water does not return to the tray. The same shelf holds All things are in flux, the line that genius is 1 percent inspiration and 99 percent perspiration with Edison named right after it, and, near Kenko, both the river that never keeps the same water and the remark that even a master once had a reputation for clumsiness. Caesar, Newton, and People go astray so long as they strive sit in that same string collection.

A completion screen separately congratulates you on all nine endings, shows your total shakes, and invites you to brag while an image prepares. Beside the counter, a gold cup can read GET!, including when the tally is shown in units of ten thousand. Nothing on the page sets up a high-score race. The boasts are how many times you shook and how much of the eight-slot book you filled. Settings can erase every in-game save, with a warning that the wipe cannot be undone. Which devices are supported is not spelled out. Next to score-attack casual web games, this one is closer to a proverb machine: the satisfaction is the absurd labor, the straw loophole, and the literary punchlines that greet a drink you were never meant to unmix.
