I wish there was a more internationally friendly version of NYT Games, they're so fun and I play them daily but a lot US cultural knowledge is required at times
Cryptic Crosswords are almost impenetrable from the US as they're so deep in UK specific words, spellings, and trivia.
That's the game! The 'inside rules' for a cryptic are what makes it cryptic. Without them you just have a word puzzle.
I've looked in the past and didn't have much luck.
