You make a good point, Aspria, but I fear the Internet has long since put paid to the integrity of prize puzzles. There's one guy - a former poster here I think - who publishes his solution to the Listener on Facebook every week. You can get answers to Saturday broadsheet prize puzzles the morning the puzzles are published. My initial reaction when some papers (Guardian, FT) used the coronavirus as a convenient excuse to cancel the prize for the Saturday puzzle was one of annoyance, but is there really any point in continuing with prizes, now we can all get the answers online?
As regards the Listener, Ginge made an excellent point last week, when he wrote
There still seems to be some "kudos" in achieving "all correct" status with "Listener" and I'd genuinely be interested in seeing the annual statistics once those "awarded" could "hand over heart" aver "all my own work" for what in the "bigger" scheme of things amounts to ...
I'm not keen on an answers thread, and I'm unlikely to have much to do with it. But I think prize puzzles are somewhat outdated these days, and although I know some solvers treat the Listener statistics as holy writ, it's time to accept that most people here treat these crosswords as a bit of fun without caring about prizes. Crosswords like this are a minority interest, and even though I'd rather not see answers given away, I'll grit my teeth and accept that if it attracts new solvers.
