Can I get a great blessing, or a curse?

No. This site does not assign fortunes at all. What comes out is one line recommending the next toy to try.

Shaking my device does nothing.

If pressing Shake gets no response, or you declined the permission, tap the cylinder directly instead. Three taps count as one shake, and the screen says so when it happens.

Is my device's motion data sent anywhere?

No. Shake detection happens entirely inside the browser and nothing is transmitted. Permission is requested only when you press Shake; if you never press it, no motion is read at all.

Collecting

koron

Shake the phone, or tap the cylinder, until a stick comes out.

How to play

Press Shake to use the phone's own movement. Where that is not available, three taps on the cylinder count as one shake. Four to six shakes and a stick drops out.

Notes on the feel

There is no good or bad fortune here. Instead of a verdict, the stick carries one line suggesting what to play next. The few seconds where the cylinder tips and the sticks rattle inside — that wait is the part that works.

What is this, really?

You tip a hexagonal cylinder, shake it, the sticks inside rattle, and exactly one comes out of a small hole at the end. It is the cylinder people use to draw an *omikuji* at a Japanese shrine or temple. The Association of Shinto Shrines explains on its official site that during the Edo period this kind of divination came to take the form seen today — one that reads a person's own guidance and fortune — and gives as one example of the ranking daikichi, the best, down through kichi, chukichi, shokichi and suekichi to kyo, the worst (the Japanese wording is quoted in full under Sources). It also says that while there is a custom of tying the slip to a rack in the shrine grounds before leaving, there is no objection at all to taking it home.

The good part is not the verdict. It is the few seconds before it: the cylinder tipping, the sticks knocking together, nothing decided yet. For that moment you would be happy with any number at all. This toy exists for those few seconds of being kept waiting.

How it is done where it comes from

A real cylinder will not release a stick if you hold it upright and shake. Tip it a little, keep the end with the hole lower than the rest, and shake along that axis. It is a matter of angle rather than force.

Here, pressing Shake uses your device's own movement. Where that is not available, three taps on the cylinder count as one shake. Four to six shakes brings a stick out, and the number needed changes each time. There are no fortunes, good or bad. In place of a verdict, the stick that comes out carries a single line suggesting what to play next — which is closer to the point anyway, since as the Association of Shinto Shrines puts it, an omikuji is read as guidance for what comes after, not as a prediction to be scored.
