Hashtag or Not
Ten made-up phrases per round. For each one, decide whether X would turn the whole thing into a single clickable hashtag. The explanation after each answer shows where the tag would stop.
Ten made-up phrases. For each one, decide whether X would link the whole thing as a single hashtag.
The rules this game uses
On X, a hashtag starts with # and continues as long as the characters are letters, numbers or underscores. It stops at the first character that isn't one of those: a space, a hyphen, an apostrophe, a period, an ampersand, an emoji or most other punctuation.
Two more rules catch people out:
- At least one letter. #2026 and #50_50 don't link. #2026goals and #3D_printing do.
- Letters from any alphabet count. #über, #Москва and #東京 are all fine.
When the game says "no", it often means part of the phrase would still link. #rock&roll links as #rock and leaves "&roll" as plain text. The question is whether the whole phrase becomes one hashtag, and there the answer is no.
A few edge cases follow twitter-text, the open-source library Twitter published for parsing posts. For example, a tag that runs straight into another # (as in #no#spaces) is not linked at all.
