How we picked these
Every entry in Detour is hand-sorted rather than scraped: filed under one category, given one to three moods, and placed in a time band for how quickly it pays off. The practical facts — cost, sign-up, sound, device and whether it is safe at a desk — are recorded per site and shown on every card, so you can rule things out before you click.
Rabbit hole: questions
How many sites are in the rabbit hole list?
222 sites, each hand-sorted by category, mood and how long it takes to pay off. 1 of them is an AltF original that run right here.
Which of these sites are free with no sign-up?
187 of the 222 are free and need no account. None of them are paid.
Do these sites work on a phone, and are they safe for work?
127 of 222 work on a phone; the rest are desktop only. 221 are safe for work and 206 work with the sound off.
