Crack Open a Fortune Cookie

As many as you like. The first cookie you open on this device is your cookie of the day, so it shows the same line if you come back later. "Open another" deals the next cookie in that day's order, and no line repeats until all 110 have come up. At midnight (your device's time) the order reshuffles.

No. It doesn't predict anything. It's a small line of encouragement for your day, and the lucky color and lucky thing are picked at random for fun. For big decisions about health, money or exams, please lean on real information, not a cookie.

Not China, despite the takeout association. A similar cookie was baked in Kyoto, Japan, in the 1800s, and an 1878 book shows bakers making them. In the US, Makoto Hagiwara is said to have served them at San Francisco's Japanese Tea Garden in the early 1900s, while David Jung of Los Angeles claimed he invented them in 1918. A mock "Court of Historical Review" in San Francisco sided with San Francisco in 1983. After Japanese Americans were forced into internment camps during World War II, Chinese American bakeries took over the trade.

Around 3 billion a year, most of them in the United States. The biggest maker, Wonton Food in New York, turns out more than 4.5 million a day. In 2005, 110 Powerball players won second prize at once after playing the "lucky numbers" printed on fortune cookie slips (per Wikipedia's "Fortune cookie" article).

Omikuji are paper fortunes drawn at Japanese shrines and temples, graded from great blessing down to curse, with readings for wishes, love and travel. These cookies have no bad-luck grade. Every line is meant to make today a little lighter, and instead of a grade you get a lucky color and a lucky thing.

Yes. The wallpaper card is 1080×1920 (9:16) and keeps the cookie in the lower part, so your lock-screen clock and notifications do not cover it. The post card is 1080×1350 (4:5), a common portrait size for feed posts. Images are made right on your phone and never uploaded.

Yes. The shared link only carries the cookie's number, so your friend sees your exact cookie (line, color and thing) and can tap "Crack my own" right below it.

Your name is only drawn on the card and never saved (it is gone when you reload). The only thing kept on your device is a random number that keeps your cookie of the day the same. All 110 lines, 20 lucky colors and 48 lucky things were written by us.
